atomic 58 inch catamaran motor question

[4343]

hi, can I put a leopard 5692 1000kv inrunner with jacket in this cat?

[4343]

anyone??

[lenny]

Hi.:tiphat:
It runs pretty good with the V700 1100kv Marine Outrunner and a sk 120a esc on 6s,
So it should work great with that motor or a lower kv one.
You may want to beef up the hull some because of the added torque of that motor,
And added weight of the cells to.
What cell where you thinking of running in it ?

[4343]

hi, will the stalk motor mount fit a leopard 5682 in there? or will I have to get another motor mount?

[4343]

down the road will it go good on 8-10s?

[4343]

I was thinking of an inrunner because I like to have a water jacket. does not look like good cooling on a outrunner? would a tacon bigfoot 60 be ok?

[lenny]

On the motor mount,
I think you will need something better.
Plus the bolt spacing is wider I think,
And the ID of the motor can is a lot bigger to.
Hear a link to some pictures of a members on hear.

I am not sure if he up graded his yet.
He also just did a kos 56" mono to FE but has not got it wet yet.

[4343]

hi, I think you wont even fit a 56mm motor mount in the arc because of the wider rails on these 56mm motor mounts?? wont fit across, will hit the ply woood?

[lenny]

No,
You may just need a custom mount made.
If the rails are a odd ball size,
No real big deal to have one made to order on hear if need be.
Do you know what the rails ID is ?

[4343]

no I dont. I tried to ask the fellow that you sent me the pics that has the boat but no reply.

[4343]

lenny, can you find out from the guy who has the arc, the id between the ply rails?

[4343]

Lenny, I found from atomik for id of rails, the guy said" I went out and measured that for you and I came up with 75.85mm" should I be able to fit a offshore 56mm $18 motor mount in there, if mount is only 67mm across?

[iridebikes247]

Can't comment on the motor mount but 1000kv is high. I would run something to the tune of 700-750kv on 12s. The boat will really move and you'll have decent temps.

[forescott]

Get a williams racing 3 inch rail mount. it doesnt have the sides like the stock mount.

[themichael]

I too am looking for a motor/esc combo for my new 58" cat (Atomik). Would really appreciate any help from anyone who knows which mount + motor would work in this hull. I like the idea of 10-12s on a 700-750kv. Not racing or anything - just looking for a reliable recreational setup. Thanks in advance!

[Brushless55]

for you guys looking to put big motor in this hull
http://www.offshoreelectrics.com/proddetail.php?prod=ose-80076
a simple 750ish kv on 8s with a gas size prop would make for a really good runner!

there is a guy on youtube who converted the gas version and used a 540kv on 10s with the stock gas prop and that sucker moved
way faster than the stock gas motor ever could

[cgd2175]

Hello, just got my ARC 58, is amazing.
Any tips for me? I just put some positive angle to the strut and cavitates alot.
38mph with the GPS
Thanks

I installed a Leopard 5692 - 1090KV last night with a water jacket. I used the existing side mounts from the motor mount. I bought a piece of aluminum from Lowes to make a new front plat for the motor to attach to. I will post pictures later. I had to buy a new coupler and replace the hose for the water to exit from the motor. The line in was the right size in length. Will run it on two 4S packs.

I also have a New Leopard 5692 - 730KV for sale.

[cgd2175]

Please send the pictures, sound very good what ESC are you planning to use?
What is the difference of using the same kv motor but with longer ones 5674, 5692, 5698 or 56110?
Here is my vid with the stock ARC http://www.youtube.com/watch?v=ffcq3VfA3nQ

[Finest Racing]

The one line is not connected for the water discharge. The original bolts that secured the side brackets cannot be used because they will prevent the motor to fit with the water jacket. Using the original side brackets will allow you to adjust the pitch. I had to make a front plate. It was not hard, took my time to make sure the holes were in the correct location. I bought new screws to secure the motor to the plate. Then solder the new bullets onto the ESC. On the second try I had the motor wires correct for rotation. Hopefully I will be at the lake on Thursday to find out how everything will work.

[lenny]

What make is that 200a esc ?
That motor will pull some high amps from it on 8s,
Also what prop will you be starting with ?

[Finest Racing]

The ESC is a no name. I have been using them for awhile without any problems. I think the current ESC will be enough for this setup. Hope to find out on Thursday.
I will try the stock prop and a prop that is the next size up that I am currently using. I will be watching the temps and be using the GPS to know if the props are working.

[cgd2175]

Waiting to hear how the setup works:thumbup:

[Finest Racing]

I am waiting to go. LOL Today was the day to go, I had to decorate the house for Christmas. Spoke to my friend about a date to go run. Looks Like December 1. He is off on Sundays and Thursdays. I am excited to see this thing run. Curious to know what MPH. Between myself, Damen and Ken we all have different predictions. Ken is thinking maybe 70mph. Damen said 60mph and I think I will see 65mph.

[lenny]

Hi,
You should post some video's of your in the video's pictures threads.

The difference is the motors can sizes and lengths will give more torque and should be more efficient,
Than the stock motor in that size of a hull.

So it should run better and faster and cooler to in the long run,
But only If the boat is setup right and running free and airs out good.

And if it is not setup right it well not be efficient,
It well run hot with low speeds and will have short run times to because of it.

I also have 4s for the new setup. I will do the same balance test as I did with the old setup. The way I did the setup on the old setup worked out very well, everything was very cool after a 4/5 minute run.

[lenny]

You will be running that 5692 1090kv motor on 4s ?
What is that no name esc rated at 4s, 6s, 8s, 12s. ?

[Finest Racing]

I will be running two 4s to equal 8s total.
I will need to check on the ESC rating.

[lenny]

If I where you,
I would not be worried about the speeds at this time.

But I would be worried about that 200a no name esc going up in smoke and everything else in the hull to, :flashfire:
especially If you push that setup and it is not trimmed out right yet.

Is this the no name esc you have in the boat now and you plan on running it on 8s ? :hide:
It is rated at 6s tops. :doh:

[Finest Racing]

That is all we need. All three of us standing there, one covering his mouth, one covering his ears and the last one covering his eyes. LOL I will do some research on a ESC. Any suggestions? I will now have an extra ESC for the other boats. I have to say, for $48 it has done very well.

[lenny]

For just to test now may be you can get the HV240a Damen has,
Most people use that 200a esc you have for 4s setups,
And 5s tops depending on the setups and boat.
So you where using that esc in that boat before on 6s with the stock motor ?
Or the stock 120a and than the 180a upgraded one ?

After the original 120a popped, I replaced it with the 200a. The 120a popped on the second time out. The 200a has about two hours of run time on it, without a glitch with the 6s setup. From day one, I have been using a 6s setup. I was using the stock motor but did replace the prop to the next size up.

[lenny]

They did not send you a upgraded 180a for the one 120a that popped under warranty ?

[Finest Racing]

Yes they did.

[Finest Racing]

Is the magic number 30,000 for this style boat? Speaking to someone and they are suggesting a 730kv with the 6s. I am thinking that would be to low in the RPM's. I calculated the numbers and 8s with a 1090kv came in just over 30,000.

[lenny]

No 730kv on 6s would be a tug boat,:lol:
Hears some numbers to look at.
The stock motor was the V700 1100kv and on 6s*1100kv=27720.RPM

6s*730kv=18396. 7s*730kv=21462. 8s*730kv=24528. 9s*730kv=27594. 10s*730kv=30660. 11s*730kv=33726.

12s*730kv=36500.

6s*1090kv=27468. 7s*1090kv=32046. 8s*1090kv=36624. 9s*1090kv=41202. 10s*1090KV=45780.

Sorry I was tired last night and did not remember to add full voltages to the numbers, :tiphat:
It is up to date now.:olleyes:

[Finest Racing]

12s*730kv=32412.

6s*1090kv=24198. 7s*1090kv=28231. 8s*1090kv=32264. 9s*1090kv=36297. 10s*1090KV=41420.

The same numbers I have on the tool box. I think I am going to stay with the 8s - 1090kv. From the stock setup to this will be over 10,000 rpm's. That is a huge difference. Thank you for the numbers.
Did not know if there was a magic number with this size boat. I think I will be very happy. I just need to charge the new batteries and go. I installed the last piece yesterday which was the water line. I may balance it today at the 30% position and mark the inside where the batteries need to go. The way I did it for the first time when I bought the boat worked out very well, either I was lucky or it was right on the money.

Not only will I reply, I will have video. I use a GoPro strapped to my hat and there is usually someone that will use a video camera.
My thought on this is that it will either run like a raped ape or be a dud. LOL
As Lenny posted with the rpm of the combo, I think I will have white knuckles.

I think Im going with the AquaStar T20 730KV from HobbyKing with the Castle Creations Hydra Ice 2 200HV ESC from OSE

I have heard some negative stories about this motor. I thought about buying this motor until I started asking around on the message boards. The one thing everyone said was that it will not last long, the second thing was that it did not compare to an equivalent sized motor. I would do some research first. I spent a little extra and went with the Leopard. Not that I am trying to sell you anything, I do have a new Leopard 5692 - 730kv. I went with a 1090kv for my battery size.
Good Luck

8 to 10s with props from 55 to 60mm

You may want to try looking into running one of these 800kv motors in it,
Not sure if fastVee or Ray has any up dates about them or if anybody has done any testing with them yet.

All completed. The new ESC is installed. One set back was that I had to use a receiver pack. Took me about an hour to figure this out. I thought I had a problem with the ESC. The only pack I had laying around was a 3,000. I thought I had a smaller one. I will look this week. As of now, I am looking at Thursday to go out and see what will happen.

[lenny]

What esc is that in the boat setup ?
http://www.offshoreelectrics.com/proddetail.php?prod=ker-seaking-130HV
If it is the SK130a HV with 180a burst you better keep it propped down,
Till you know what amps you are pulling with that motor.
Because that motor will pull some high amps though that setup if you over prop it.
And are you going to be testing this setup on 8s to 10s ?

[Finest Racing]

I will be running 8s. Tomorrow my equipment will arrive to measure everything. Then I will know where I am at.

Ok cool, :tiphat:

Just did not want to hear about any smoke with this test run. :beerchug:

[Finest Racing]

I went out today. It was low 60's here in south central NJ. Unlikely that we will see that again till spring. The Atomik had a glitch on the first pass. The water feed line came off going to the water jacket. The boat filled up with some water. Brought it in, fixed the line, topped off the batteries, watched Ken fly around with his Genesis.
Reset the GPS, secure everything and try it again. Off the work bench into the water the boat appeared to be on the money. I was using two 4s 6000, 25~50c Turnigy Nano Tech batteries. I know they are under in the C rating. Surprised after a 3 to 4 minute full burst straight away runs, the batteries were at 85 degrees, the motor was at 90 and the ESC was at 88 degrees.
With the GPS tuning off but recording the max speed before turning off due to low battery, I recorded a max speed of 59.3mph. I was a very smooth ride. Ken did the video and Damen did the still photos. When I receive them, I will post.
All in all, I am happy. No tweaking was done today. I just enjoyed it. I will now tweak it a little to see if I can hit the magic number that we think it can hit (70mph).
I did roll it, which landed right side up. I think after the first roll - the battery tray separated. The boat was leaning when accelerating from a stop. After moving it would level out. The problem was when I would release the throttle the boat get loose. The boat rolled two more times - always landing right side up. No other damage or problems to report.
I did use the data recorder. I will check that tomorrow.

[cgd2175]

59mph...nice!!!!

Ok hey you guys, It has been two weeks now. :lol:

So what the hell happen ? :popcorn2:

Do you need a flash light and a mirror to look for the data, pictures, video's that Damen & Ken have ? :moon:

If you rigged it to you tx and followed all the action in the foreground instead of trying to say in front of the cam.

I shoot all my vids like this now when I need to,
Just aim the tx like a gun at the boat or what ever you are running.
It takes a little time to learn but works pretty good,
I still need to learn how to follow and zoom and drive at the same time with out screwing up the run. :lol:

if it works fine testing bats and weights then im placing a lipo order to run 2 6s in parallel

I spoke to Damen, he is working on the pictures. I have not spoke to Ken yet. It has been crazy over here. It was my daughters birthday this week. I will be calling Ken tomorrow.
I will be checking the data tomorrow too.

I also use a GoPro using the head strap. Your head is always following your boat.

I could not go to test the new motor yet, I forgot that the shaft 6mm shaft coupler is on its way from OSE with other stuff but what amperage do you think is going to draw? Also want to put order on new 6s lipos to go parallel but Im not sure if Im going to need 65c of discharge.
The T600 1400kv motor is rated up to 8s with ...rated for 3250 watts
Planning to use the stock 54mm 3 blade prop, what C rate do you think I need running in parallel config?

I would use 40c turnigy,
Unless you have more money to through around.

Do you have a speed that you are trying to reach?

[cgd2175]

50mph...
Yours ran ok as I read with the 5692? near 60, very nice!

[Finest Racing]

The reason I ask is that the stock motor can hit 45mph. I had the stock the motor at 45mph without any tuning or adjustments.
With my new combo, I am going to bump up on the prop and fine tune it. I hope to hit 64-66 next time out. I am going to view the data tonight. This will tell me a lot.

[lenny]

Chris You should change all your connectors to basic 5.5 bullet,
That would be a very good upgrade for the whole setup.
My P1 KOS stock v500 2000kv runs pretty hot to some times,
Temps in the rang of 130f and up to 210f some times is normal on the these outrunners.
But with a little higher timing it help it run a little cooler for me,
Do you have a temp prob for checking temps ?

[cgd2175]

Yes everything goes cc 6.5 as I'm putting a CC 240 I want to try and standardize my escs, motors and batteries. The traxxas connector is temporary. In my test I'm going to take temps also and share.

[Finest Racing]

The Traxxas connectors gave up on me in the middle of the lake. One time the plastic got soft and reshaped itself. The next time the solder let loose and the wire came off the contact.

[ray schrauwen]

If I knew the weight of the hull empty I could get a better idea of what is possible for this large hull on 6S and 1400KV.

I ran the T600 1400kv motor on 5S2P old PolyRC cells, 10000 mah total. I ran it for 6 laps plus mill racing on a full course in a 29" Promise hobby cat. The hull could handle the power because it was 3.5lbs EMPTY!!

I was turning a D/T x450 2 blade and the motor had a Vantex Water cooled motor mount. Came back fairly hot but, once an out runner is in the air it cools off much faster than an inrunner since every thing is more exposed to air and the magnets are on the outside. I had the strut set level and even with the bottom of the sponsons. More tuning would have helped but, it was a quick idea before a race.

You won't be able to turn the stock prop on 6S for very long without something going stinky, that's a really big wheel to turn.

I ran a T180 esc on fairly stock Auto settings so there is probably a best program that I never got to.

If I had the hull I'd run the T600 880kv motor on 8s -10S starting with a 450 prop then see what is possible.

Lenny, I should have bought that used T600 1400kv motor when I had the chance.... oh well.

If anyone wants T600 880kv to test out let me know I have 2 kicking about.

I sold the 1400kv long ago and mounted a 880kv back into the 29" cat. Spun it up on 10S1P but, never ran it.

Maybe I'll charge the cells and take it out in the snow.

With 5S2P, x450 D/T T180 that 29" cat was hauling out at about 50-55mph....

This
http://www.youtube.com/watch?v=BkVJ345GkLY Shows when I ran it and you can see my orange cat pop out from time to time. The camera was on a 48" cat running 10-12S on a big lehner and Schulze 40-160 esc. I could keep up but, the rudder was too short to handle the corners effectively.

[Doby]

That was a fun heat!

[FastVee]

Hi,replying here to the pm.

I can only tell you what I think but:

the 880kv T600 motors I have used were ok but the~54" v-hull needed 2 of them and they were just ok, they were not running too hot but 1 is def not enough on it it needs 2 of this sized motors to work.

The 910kv motors that I have in it now are much more powerful and they run about the same temp as the 880kv but heat the esc and lipos more.

I use 57mm 2 bladed prop usually and it is perfect for the boat.


If you want to use 1 motor I would suggest lower kv, the 30k most suggest for fe is not needed to get the boat to go 50mph. (15k will get the boat to 30mph on 4s! (http://www.youtube.com/watch?feature=player_embedded&v=mixrGwxJ_K8))

The cat is lighter and easier for the motor so 1 motor could work in these 700+ sizes but I would try about 51mm prop first.

I am building same size cat atm and it will have 2 1250kv motors and I will aim to 60mph on 6s.

Something to think about...

I’m expecting this week 2 props to test, both 3bld CNC from OSE, one is 52mm and the other is 50mm. Also a 2bld CNC of 55mm.
I am used to gas boats and 70-75mm props, and now I’m trying to start and probably convert some of my gas boats to FE. The biggest prop that I have at this time are, Octura M445, X648, a Prather 230 and a GrimRacer 42 x 55 from my Nitro Shockwave.
I´m not sure if these smalls props can put in plane this Cat, I´m learning.
This Atomik ARC 58 is going to be my real entrance to testing, gathering and learning from all of you.

I worked 12 years in the PPC Panama Canal Com. when was US admin. You can see my Mag57 runing in the Panama Canal jejejejej!!
I am addict with the rc hobby, in one trip to FL I went and met Tony C. from warehousehobbies/bonzisport now... and a Magnum 57 was my first real gas boat, still running amazing!!!!
And now trying to make my ARC 58 more fun :smile:

[lenny]

I have a big cat hull that I need to put back together some day,
It had a blow over at 80 mph and the guy was selling just the hull with no hardware.
So I need to find hardware for it and still fix the hull up,
I picked up a brand new 26cc KOS P1 motor to try and run in it.
This is what I have so far for it,
You see it sitting next to a 37"Daytona in the one picture.

Hear are some links of it's first build before I got it,
Let me know if they work ok.

Ray,

Length: 53.5in/1360mm

You need a BIG motor or twins. Thats heavy but, normal for that size of boat. A big 56mm diameter TP Power motor on 10-12S would do the trick. 600- 800 kv and your big prop it came with.

[Bri6672]

Hey Guys,

I have the ARC 58 and am happy with the stock performance running 2) 6s 5800's in parallel. I'm getting nice 8min run times with the packs still sitting in the upper 3.7's.

So I'm posting cause the motor is running pretty hot so I want to change it out but want to keep running the same packs and ESC (v2 180amps)

I am wanting to run the leopard 5692 1090kv but don't need the 60 plus mph speeds finest racing is getting. I am wondering if anyone knows what that motor will do on 6s? It is 10 less kv than the stock motor and is an inrunner vs outrunner, it is obviously a larger motor so not sure if that makes up the difference in kv??? I just don't want to put that motor in and loose any performance, a nice bump would be nice but not necessary!

Any feedback would be great!

I am at this speed with a different prop. I did not run the current combo with the stock prop. We will run the stock prop when we go back out. I would like to know the difference in speed with prop sizes. Don't be fooled by this boat going 60mph on a lake. Remember the size of the boat and the size of the lake or where you are running. At 60mph, it was not bouncing all over and hard to control. It was a smooth ride. I was actually surprised to see how it was handling the water without any tweaking. I do have the hull marked at the 30% point. So far this has been working with all my boats. When the video is available, we will all see the smooth ride. Who ever came up with the 30% theory was brilliant. Even with the battery tray separated, the boat was still great at full speed. LOL When accelerating and decelerating she was all over. Your thought on using 12s - 1090 x 22.2= 24,198. My goal was to be near 30,000 to be efficient. With my combo - 1090 x 29.6=32,264.
I am not sure if this would be the way to go (24,198) I am not sure if this would cause the ESC, batteries and the motor to get hot. The stock set up with the 1,100kv motor and a 12s set up would be 24,420. The stock setup was also an out drive which will run a little cooler.
Good Luck.

[forescott]

Sounds good, but you won't be able to use the stock motor mount with that motor. Once you put a jacket on it it will be too wide for the mount. I would think the leopard would gain you a little speed being that it is probably more efficient than the stock outrunner, but you may be pushing the limits of that 180 amp esc. I did run a leopard 5692 1340kv on 6s with the t-180 esc with success. But that was in a 45-inch hull.

[forescott]

Ive been waiting for the motor or esc to quit in my ARC since I got it two years ago. I have the first version with the 120A esc. and I run a single 5800mah 25-50c 6s pack. Still running..........But the motor gets extremely hot. Last time I ran it I could smell it starting to burn. The out runner relies on lots of air to keep cool. Unfortunately the water cooled motor mount doesn't do much good, and the air flow through the hull is minimal at best. Eventually I will upgrade.

[Finest Racing]

I had to make a front mount for the motor. I reused the sides. I bought the aluminum flat stock at Lowes. Installing the screws are tedious. You will need patience. It is a very tight fit but will work. After I cut the aluminum, I drilled the four holes - one in each corner to secure it to the side mounts. Then drill the holes for the screws to secure the motor to the mount.

[forescott]

Yeah, it would have been nice if they left the rail spacing @ 5" like the gas versions. I have the 56" P-1 converted. It has 5" rails and there is tons of room.

Well on 6s the 1090 leopard should be fine with the 180amp ESC.... I have heard the stock set up is pulling 110-120 so even if it went up 10-20 amps it would still have headroom!

Does anyone have any real world expierence with the 1090 in this boat on just 6s??

[cgd2175]

the Leopard LBP5692 is rated at 5500w, 35v with max amps 160A.
I know that watts x voltage= ampers
My question is if I use this motor in 6S(22.2v) the amp draw will be 247.74Amps?
5500w/22.2=247.74 is this the way to calculate the theorical Amp draw???

The load and kv play a big role in this, change the prop and the amps are going to change....

[cgd2175]

so the 5692 1090kv in 6S will draw 250amps minimum?

[Bri6672]

so the 5692 1090kv in 6S will draw 250amps minimum?

No way.... More like 110-130!!!! The 1100kv setup is only pulling 115!!!! The inrunner vs outrunner and pole count play a large roll but kv, voltage and prop are he main detirmining factor for amp draw!!!!

[cgd2175]

to determine the amp is not what I thought in this application: watts x voltage= ampers
I have a lot to learn,
How can the amp be figured out? for example...to know what batteries C rate to buy or to know what esc to use?

[Bri6672]

It's all about the load! The prop, weight of boat etc... All play a role!

Hey Rob do you need some batteries for the flash light or may be a bigger mirror ? :bounce:




Ok hey you guys, It has been two weeks now. :lol:

So what the hell happen ? :popcorn2:

Do you need a flash light and a mirror to look for the data, pictures, video's that Damen & Ken have ? :moon:

[Finest Racing]

Spoke to Damen today, he said he would upload the pictures tomorrow. I knew I should have used my video camera. Ken did the video. I will call Ken tomorrow to see when he maybe uploading the video's.

[Finest Racing]

That was how I was going to do it. Where did you get the coupler and what size is it??

Depending where you buy the Leopard motor, will depend on the size of the shaft. Offshore has the motor with a 8mm shaft if I remember correctly and the motor I bought had a 6mm shaft. Both motors are legit/authentic motors. I bought the coupler at Offshore.

[Bri6672]

Ok so I am going with an HET 700 98 1170kv. It is basically a copy of the Neu 1527 but a Better kv for 6s. Going with a water jacket and a rear mount clamp to support the 4"s of motor. This should be a good bump in performance but allow me to stay at 6s and get good run times with the 11600 mah I am running.

Boats are kind of a side thing for me hobby wise, I normally play with big 20-30 lb EDF scale jets and I have been running some HET motors pretty hard in jets the past 2 years and have had great success so I decided to give them a shot in a boat. I am going to make a new front mounting plate for the motor mount (if I can't modify the stock one) I am going to attempt to use the existing motor shaft coupler and drill out the motor end for the 8mm shaft if that dosent work we will just fab a new one

All the stuff should show up end of this week and I will post picks of the build and the performance via video, hoping for the upper 40mph range maybe touch 50 but still have the convience of just 2 batteries per run and a good run time (7-8min)

[lenny]

I went out today. It was low 60's here in south central NJ. Unlikely that we will see that again till spring. The Atomik had a glitch on the first pass. The water feed line came off going to the water jacket. The boat filled up with some water. Brought it in, fixed the line, topped off the batteries, watched Ken fly around with his Genesis.
Reset the GPS, secure everything and try it again. Off the work bench into the water the boat appeared to be on the money. I was using two 4s 6000, 25~50c Turnigy Nano Tech batteries. I know they are under in the C rating. Surprised after a 3 to 4 minute full burst straight away runs, the batteries were at 85 degrees, the motor was at 90 and the ESC was at 88 degrees.
With the GPS tuning off but recording the max speed before turning off due to low battery, I recorded a max speed of 59.3mph. I was a very smooth ride. Ken did the video and Damen did the still photos. When I receive them, I will post.
All in all, I am happy. No tweaking was done today. I just enjoyed it. I will now tweak it a little to see if I can hit the magic number that we think it can hit (70mph).
I did roll it, which landed right side up. I think after the first roll - the battery tray separated. The boat was leaning when accelerating from a stop. After moving it would level out. The problem was when I would release the throttle the boat get loose. The boat rolled two more times - always landing right side up. No other damage or problems to report.
I did use the data recorder. I will check that tomorrow.


I spoke to Damen, he is working on the pictures. I have not spoke to Ken yet. It has been crazy over here. It was my daughters birthday this week. I will be calling Ken tomorrow.
I will be checking the data tomorrow too.

I also use a GoPro using the head strap. Your head is always following your boat.

[Bri6672]

110076Ok so motor and parts all showed up today, the water jacket for the Neu 1527 seems to be a good fit for the HET motor.I need to drill out the motor end of the drive adapter from the 6mm stock size to fit the 8mm motor shaft. The bolt pattern of this motor seems very close to the stock motor mount so I might just try modifying the stock mount before going thru the hassle of making a new one. I'm going to try to get an amp reading with the stock motor first then compare it to the new motor.

[Finest Racing]

Be careful when drilling through the motor mount. The mount has water jackets. Even though you may not be using the water jackets you will weaken the structure.

[Bri6672]

Yep, not my first rodeo. Most likely just bringing the pattern in a bit, atomik says its 28 and mine is 25 so not to far off...

[cgd2175]

One question, that motor is not too small?

[Bri6672]

One question, that motor is not too small?

40mm by 4" it's much larger than the stock motor and can handle way more power!! These motors are consistently pushed over 4000watts.

[Bri6672]

Maybe this will help:110078

[Bri6672]

Getting closer! We machines the mounting holes for the factory motor mount and drilled out the stock shaft coupler and everything seems to be going together well. Still need to do some alignment of the motor mount and tighten everything down, hope to have it in the water soon!

110161

[Finest Racing]

Looking good.

[lenny]

Looks like a nice fit. :tongue_smilie:
But change the water lines on the motor jacket so that the water come in at the bottom nipple,
And than fills the jacket up and over flows out the top nipple to the exit line.
It should help cool the motor a lot better that way with more water around the motor can,
I try to get the exit nipple on the very top of the motor when possible :tiphat:

Yeah I was kind of thinking that but was also thinking it would be easier to flush the system out if the exit is on the bottom ( I run in salt water) cooling is obviously more important so I will flip it around.

[lenny]

Just turn the hull upside down if you need to get the last drop out,
When flushing the setup out and hull.
Also spray some WD40 in the lines and blow it though to help keep down some corrosion.

110202
I'm preparing my ARC...

[Bri6672]

Ok so I was able to get out for a quick test run today!
So conditions were not ideal, pretty windy and some mild chop so it's hard to give a detailed comparison between my new motor and the stock but I will say its definitely an improvement in performance and the motor seems to be running pretty cool!

This motor is designed to produce some serious power and the 2500-3000 watt estimate that I am seeing is not even waking the motor up! I will bring my temp gun on the next outing but things seemed really cool!

Performance wise this is a nice step up from the stock motor, I am running same batteries, ESC and prop so it's just a straight motor swap.

At full throttle the boat would not stay in the water :) I would guess that 3/4 throttle with this motor is similar to full throttle with the stock motor. The conditions kept me from really seeing what it can do but if I was to shoot from the hip it's about 10mph faster. I have run the boat in similar conditions maybe a bit less wind and I was able to get some full throttle passes but with the new motor that was not possible. Every time I hit full throttle you could see the drive shaft and prop coming out of the water, it was very impressive;)

I will try to get out and run it glassy conditions and can give a better assessment but so far I'm really happy with this upgrade!

[Bri6672]

So I got another quick run in today, this time it was in good conditions. The het 1170 kv motor is a perfect fit for anyone that wants to stick with the stock ESC and 6s but looking for improved reliability and a nice step up in performance!

The motor only hits 110 degrees with the water jacket. I would guess its a good 10mph faster than stock.

With two batteries (6s 5800 in parallel) it helps keep the boat locked in pretty well and give you enough capacity for 7-8 min run times.

Next time I can get a buddy to tag along I will try to get some video.

[cgd2175]

Thank you for the info. With what prop you test with the stock one?

Yes all stock only changed the motor and the radio system...

4 more runs today and all is good! Motor is sitting at 80-90 degrees after 7 min runs. I have an eagle tree data logger and will run it next time to confirm the amps I'm pulling. Love this boat with this setup, lots of fun!

[Bri6672]

Wow this thread has gotten pretty quiet...

3 more runs on my ARC today and i used me gps data logger to track the performance top speed was 55mph in mild chop! I'm super happy with the setup, it's reliable and allows use of the stock setup other than motor! I was get some amp readings next run.

[forescott]

My arc the last couple of runs has been coming in waaay hot! Just under 200 degrees with about 6 minutes run time. Looking for ways to keep the temps down in the 150 range. I swapped the t-120 it came with for the t-180. Esc was 84, and single 6s 25-50c zippy was @103. Seems like the motor may be going out or maybe I need to free up the prop a bit by raising the strut? Thinner lube on the flex shaft? Maybe even an electric fan in front of the motor? I really don't want to replace all the electronics to something bigger. The boat is really light and runs a consistent 40 mph in its stock configuration. Any more ideas??

[lenny]

Any vid yet ?
What timing are you running with that setup,
Also can you post some pic of the inside setup to have a look ?

[ray schrauwen]

The bearings on the stock motor could be going. Replacing them may help bring temps down but, 6 minutes seems like a long run to me, but, thats just me.

[forescott]

Any vid yet ?

18 degrees I think. I bumped the timing up one setting from the esc default setting thinking that an outrunner typically likes higher timing. I will definetly drop the timing and see what happens. I consistently get 40 mph on GPS, so ill check the speed to see if the reduced timing has any effect. Good thinking!

[forescott]

6 minutes seems reasonable to me. Only running a single 6s, 5800mah pack. If the bearings are bad I'd more than likely just replace the motor.

[forescott]

Sorry Lenny, I've been trying to figure out how to film and drive at the same time. I have an old flip video camera I'm trying to mount to my transmitter. I've got a couple of runs on the big 56 inch p-1 as well, but having some handling issues and a pinched o-ring on the cooling can caused the hull to fill up with water on the first run. I'll get some vids posted soon.

[lenny]

Flip phone,
Maybe have the bottom of the flip phone flat against the bottom of the tx with some straps of velcro holding it there.

On v500 outrunner I moved the timing up when testing from 15% to 26.25 and it runs cooler,
With still good power and run time to.

Those outrunners do run a lot hotter normally than the inrunners do,
But I think they can handle it better.

Also check that you still have good water flow to the mount,
And at water pickups and nipples of mount to.
Their could be some debris slowing the flow of water to.

Really? I was always under the impression tha more timing meant more power and more heat. I'll have to do some testing for sure. And I have an idea for the flip camera. Will give it a shot early monday or tuesday.

[forescott]

I did a little reading on motor timing, and it seems that more timing equals more power but less efficiency, however motor pole count is the big factor. A motor with more poles will typically have higher timing. So I guess that makes sense that the 8 pole t-600 would require higher timing than a 4-pole in runner. I bumped my timing up to 22 degrees and swapped all the connectors from stock 4mm on the motor to some castle 6.5's that I had lying around. Also raised the strut just a bit to free up the prop. Tomorrow Ill run it again and compare the temps and top speed.

[lenny]

Yes the 6 pole outrunner are a different animal of motor for sure.
When I was testing and reading about them,
They called for a lot higher timing for most of them.
I know Ben at fightercat had said to put them at 15% timing or they will run hot,
Hear a link to some info on the stock venom motors from pasted boats.

Also raised the strut about 1/4 inch to free up the prop.

Good to hear about the temps.
Vid looks pretty good to for the first time on the tx,
The boat looks like it is riding nice to.
It will get better and easier the more you use it like a side arm gun,
Or like shooting from the hip.
Keep testing with more timing and see how it likes it,

Do you need a flash light and a mirror to look for the data, pictures, video's that Damen & Ken have ? :moon:


I went out today. It was low 60's here in south central NJ. Unlikely that we will see that again till spring. The Atomik had a glitch on the first pass. The water feed line came off going to the water jacket. The boat filled up with some water. Brought it in, fixed the line, topped off the batteries, watched Ken fly around with his Genesis.
Reset the GPS, secure everything and try it again. Off the work bench into the water the boat appeared to be on the money. I was using two 4s 6000, 25~50c Turnigy Nano Tech batteries. I know they are under in the C rating. Surprised after a 3 to 4 minute full burst straight away runs, the batteries were at 85 degrees, the motor was at 90 and the ESC was at 88 degrees.
With the GPS tuning off but recording the max speed before turning off due to low battery, I recorded a max speed of 59.3mph. I was a very smooth ride. Ken did the video and Damen did the still photos. When I receive them, I will post.
All in all, I am happy. No tweaking was done today. I just enjoyed it. I will now tweak it a little to see if I can hit the magic number that we think it can hit (70mph).
I did roll it, which landed right side up. I think after the first roll - the battery tray separated. The boat was leaning when accelerating from a stop. After moving it would level out. The problem was when I would release the throttle the boat get loose. The boat rolled two more times - always landing right side up. No other damage or problems to report.
I did use the data recorder. I will check that tomorrow.

I just picked up one of these, bare hull and wondering what would be a good motor, that would bolt into the stock motor mount? Plan on running 6s.

I was looking at this motor, seems comparable to the stock motor, or should I go with a different KV or different motor?

What speeds are you looking for with that hull ?

What speeds are you looking for with that hull ?

Around 45 would be good,

Was also looking at this motor too, just unsure of what KV to get

Also, what sized flex shaft does the boat have, I haven't picked up the hull yet, just want to get what I need beforehand

Thanks for the info in advance :thumbup1:

[forescott]

you want the 1100kv version of that turnigy out runner. Are you getting the ARR version of this hull with the stock hardware or just a bare hull. The stock flex cable is 1/4" with a 5mm prop shaft.

[birdy233]

I'm getting the ARR version. Would the fightercat motor be better than the Turnigy?

[forescott]

They are actually the same motor. You'll notice the fightercat description says t600. They just have his logo on them. Either one will work just fine.

[forescott]

Doesn't the arr version come with everything but the radio,motor, and esc?

[forescott]

Remember you'll need to pick up a motor coupler (6mm motor shaft to 1/4" flex cable). Even if the arr version comes with one it will be a 5mm to 1/4" coupler. For some reason the stock rtr outrunner comes with a 5mm motor shaft.

Not really. Thge motors at HK designated as T600's are larger than the motors FighterCat calls T600's. FC calls them T600's because they were originally designed for 600 sized heli's.

If you type in T600 at HK you will get the range of T600 motors in 880, 1100 and 1400KV.

What fighter cat calls a T600 are Suppo motors slightly smaller that the HK T600.

Below are pics of the HK versions. The chrome ones in second picture are the Suppo and same as FC and are less expensive than FC. The black case ones are HK's T600 line and can produce more power and are physically larger.

I have one each of the motors in Ray's pictures above...he's right, there is a fair difference in the size of the two.

[birdy233]

Thanks for the info guys! I ordered the Turnigy 1100 Kv motor and the proper adapter for the flex shaft. Running 6s, could I get mid forties?

And what can I do to add some better cooling, I was thinking of fabbing up a fan mount for the motor

[lenny]

Vents would be nice but you need to keep it top side up.
I had found some foam that would let air through it but not water,
But I never got around to modding it into a boat hatch to do some testing with it yet.
Try looking into a very good outrunner water cooled motor mount for it,
And added with a fan I think that will help a lot.
Talk to Herve in this thread and see if he has anything new up his sleeve.

Sorry for the mis- information, and thank you for the correction. :blush:

I got a new set of turnigy nano-tech 5000mah 35-70c 3s lipos to replace my single zippy 5800mah 25c 6s lipo in my ARC. So went from 145 available amps to 175. Also bumped up the timing from my last run from 22 degrees to the maximum 26.25. The boat ran slower from last time. Went from 43.7mph to 42.1mph, and motor temps increased from 130-165. Looks like The optimal timing for the stock setup may be 22 degrees. I don't think the higher c-rated lipos made any difference, but it is good that I have the batts down lower in the sponsons instead of on top of the tunnel. I'm loving this boat right now! Super fun to drive, and handles better than expected for such a scale looking hull.
