Just bought a Apparition twin from the SS and need some help choosing motors. I did a search have found most folks running the Feiago 380xl's on these hulls and the ekos hulls, but I don't want to go that route. I do have a question though will a 540 36mm can fit? I know Bill O upgraded his EKOS to 540 cans by just modding the motor mounts, just curious if anyone has tried it with the apparition hulls. I know the ekos hull is a little bigger though. I will be replacing the 4mm bushings on the strut with some 3/16 aeromarine bushings and I will use .150 3/16 flex cables that I already have (the cw mg cable and the replacement ccw mg cable).

A) Leopard 2860 2730kv on 3s
B) Leopard 3650 2930kv on 3s
C) Ammo 3650 2300kv on 4s
C Ammo 3656 2600kv on 3s/4s
D) Ammo 2845 2700kv on 3s

Esc's would be twin seaking 120s.

Another question is should I run isolate each esc and battery or should I parallel the esc's and parallel the batteries on 3s and if I ran a 4s set up should I parallel the esc's and run 2 2s batts in series or parallel the esc's and run 2 4s batts paralleled?

Id definitely not run a 2 pole motor.Stick to a Leopard or other decent quality.I ran my EKOS on Feigao 380XL's 2612kv on 4s.Ran cool,but just lost a motor recently too.Im re-building using Arc motors from www.lightflightrc.com. My friend has an Apparation,and by looking at our 2 hulls,they seem to be the same in the sponsons as far as room goes.And Arc 540 motors have 25mm and 19mm bolt patterns too.You can also use more rpm than what you posted in the poll as far as the Leopards go.Or prop up.32,523 isnt much for a twin drive.

Me personally would use the ammo 2600's or the turnigy 36-56-04 2600kv. I ran both of those motors in my blackjack twin and the both yeilded exactly the same speed. (right under 70mph) run em on 4s (2 2s in series) and the speedys in parallel so each motor see's the same voltage. Same setup in my Miss Geico twin ran 66mph on x442's on 4s.

Twin 540s, 10XL, 6S, just over 70mph.


EDIT, oh theres more... I got excited and posted too soon... Mine is wired as Blackcats, 2-3S, seriesed to 6, the paralleled out to the EScs, BUT, if you run 4S or even 3S per motor, obviously theres enough room so run it to each seperately so youll get a longer run time. I actually just purchased two 4S 4000mah 40C packs that will just fit under the deck lip that Im going to run mine on. 70 is cool, but for the 1:30 sec saw runs, it will be alot more fun a little slower. My test runs will be this weekend on the new power provided the weather holds up.

So I looked at the arc motors and im really liking the 36-55s. I like the 2800kv but for 3s its going to get me in the 31k range and you say thats not enough for twins and 4s is over 40k so is 40k to much on twins or what kv rating should I get? The dual bolt pattern me likes a lot.

The leopard 2730 on 4s would yield around 39k, so better on 4s then 3s for this twin?

The arc 36-55 1850 on 5s or 6s is looking good, I'm looking for saw style runs on this. Run time isn't a issue, but temps are a concern. Looking a x442 & x447s, but will start with cf40s & cf45s, not sure how the 55mm will handle a x447. The 36-65 2080 on 5s is another choice. I'm so confused lol....

From several discussions w/ Mudl, 55 length cans arent going to do what you want them to. From his findings, the difference between that size can in a BJ26, compared to a HOTR hull is A LOT of mph. I was going to put 3655 size motors in mine and he talked me out of it.

My ekos runs 38,600 unloaded rpms on 380- xl motors(2612kv) I only run it a few minutes at a time but they don't get hot. I think you can get away with pretty high kv motors on a twin cat. The load split between two motors allows for more rpm than the typical single setup.

I ran the ammo 2845's in the ekos on 4s. It ran pretty good. The feigao 380-xl's are pretty impressive too. Could be another option!

We all know how mudl's twin projects go, so with that being said i will not go with the 55mm can's lol, I do want to try to go with the arc motors though, I have never owned one before and kinda interested on trying them and I think the dual motor mount range is cool. How do you feel about the 36-65 can? The 2080kv on 5s will put me around the 38k range. So we can see the page I am looking at, it was listed in above post but I will re-list http://www.lightflightrc.com/

sweet deal. Yea that's what I use. I do cut up small pieces of fg into the resin for small repairs though and to strengthen existing motor mounts. Based on your findings with the 36-55s will determine if I re-drill 25mm holes in the mounts though. If they work ok I will try those motors out, if not I will re-drill and slap on leopard 36-74 1900kv on 5s in the boat. That should rock! What esc you gonna run with those arc's and what kv rating you looking at?

If your boat came with 380's,the 36 55's will bolt up.19mm is 380bolt pattern and 540 is 25mm.I'm reusing ekos mounts and going to make rear motor supports.my motors are 2800kv on 4s and using seaking 120's.

I bought it in the swap shop, id imagine its the hk version so I'm sure its gonna have the 19mm bolt pattern which is y the 36-55s looked great for the price, bolt pattern and pole count. If mudl and tiq aren't sure they will work good that sucks. Waiting on your build to see what happens. What props you plan on running?

Should start the build Sunday or Monday.using 36mm venom,38x55mm tfl,and x442's.id like to use outrunners,but I'm afraid they will run hot.I don't think motor mount cooling does much.ill try the arcs,and you can make your decision.I would have gotten the same kv, but in a 380,but they are out of stock.I kinda like to be the underdog and still put the hurtin on bigger motors and voltage.

12-08-2010, 08:47 PM
Im only basing my comment on what was recommended, or not recommended, to me. I think Mudls advice is pretty darn powerful though seeing how is builds turn out. I wanted to copy his BJ26 twin build for my HOTR. His comment was it wouldnt be anything like the BJ and thats why he recommended a XL size can. BUT, it all depends on what your goals and expectations are..... 36-55s may be just what your looking for.

blackcat26
12-08-2010, 09:28 PM
I agree with Tique the xl's are a little better suited. The L cans will work but xl's better. I was just choosing from the parameters you listed. Anyway get off your butt and buy the 10xl's that are in the swap shop as we speak........

Thanks Baked.The 36x55's are already in the mail,so Ill use them.To get back to Diesels thread,I hope he buys the Feigao XL's.Id like to compare the two brands and two and four pole as well as length.Im sure both will do very well.Is Diesel still here?Havent heard from him.

I'm still here bud, just reading and been looking. I am leaning towards 540xl motors, but not feigaos (been down that road, want to move to next). I am leaning at leopard 36x74 1900kv motors with octura x442s with seaking 120's on 5s. The wife said the boat arrived today so once I get home I'll see what I have to work with. I wonder if the rpm will be too low though at around 35k, any thoughts on that?

By the way my goal here is low 60s and reliable.

PS. You not taking away, we both are building up the same hull and we can share our learnings, questions and findings on this thread.

Well I got the boat yesterday. Def needs some work. Still had the square drive portion of the flex stuck in the stingers. I removed those as well as the stuffing tube. 1 off the water tubes epoxy broke loose as well. I accomplised that yesterday, today at work (instead of working :spy:) I pulled the stingers out and removed the 4mm bushings and replaced them with some aeromarine 3/16 bushings. I was able to pull the outer bushing out with a easy out, then pounded the other bushings with a punch. I drilled out the stingers with a 1/4 bit and pressed the new bushings in. Not much room to drill in those things and you have to drill SUPER straight. You can see how big the new bushing is, the stock system came with 2 4mm bushings installed, i just installed 1 of the new bushings. I think it should be ok considering both old bushings are as long as one of my new ones. I will use the MG flexcables 1 cw, 1 ccw, thank you Proboat and HH!

I think chuck e cheese used the typhoon in his hotr cat and was running 50-60 if I recall correctly.

I'm no prop guru but I beleive de-toungued props has lees holeshot and more top end. But with twins you have twice the blade area so it doesn't make much matter. Adding cup and or pitch will redirect the thrust cone so you'll have more speed. Counter rotating props are limited in sizes so alot will be modified.

Just so all of us are on the same page this is the motor I have http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=9258. I planned on using in a BJ26, but I also have suppo outrunner coming that I can use instead. Since i have one and they are priced cheap they may be worth a try. Once I open the motor mount to except 25mm bolt patterns the sky is the limit. It maybe worth a $50 try for fun. I love that outrunner sound!

Diesel, you are killing us! Put some xl's on it or some Leopard 36mm and lets cook! I don't know about those outrunners castle sells because I didn't see any specs on em. If you want outrunners get Scorpion's. hk 3026 in 1400kv or 1600kv 0r 1900kv. They have proven power and Mudl has got 87mph out of his Genesis on em.

HAHAHAHA, I am. Im putting Leopard 540xl's in (3674 1900kv on 5s). We can't cook, it's too damn cold. Which is why all the questions. Nothing else to do but discuss options and what not can't actually run anything yet. I like picking you guys in brain, gotta ask questions if you wanna learn :popcorn2:

PS got the mount, thank you good sir!

Those 380 10xl's should bolt right in Ron. I'm pretty sure the HOTR comes with 19mm bolt pattern so it should go in no problem. Will be a lot better then the stocker. The Venom ekos guys are using them with no problems.

I ran the 380 9XL's in my EKOS on 4s.Ran very good.They used to be rated at 2612kv,but I think the kv ratings got changed.These motors dont have good high quality bearings for extended high rpm use,but Im sure Ron will do just fine with his 10XL's on 4s.

I'm waiting until after the holidays to get back into this project. I splurged on my old lady so I'm broke as a joke. I'll pull the motor mounts soon and re-drill them for 25mm motors. That's my next step. Sorry your hull came cracked, that blows!

Diesel, is that the Suppo? Are they the same as Himodel? Heres the Himodel from Mudl for the Genesis esc, but aslo has a 70A version

Could be the same intrusctions.. I didnt compare..

I'm pretty sure the some of the "Himodel" brand esc's are suppos. Not sure if all of them are though. The one you listed from ebay I believe is a Suppo sold by HOTR. Most of the artr we get from from China with the yellow wrap like that are suppo's. I know when I bought my Genesis from HK it had a suppo in looked like the one you pictured but it was the 125amp version.

SUPPO™ Speed Controller Programming Instructions
For Advance programmable Normal Boat ESC
70A/125A/200A ESC
Important Note: Some of these ESCs are Opto, without BEC to your Receiver,
you need extra power source for your receiver. You can use a UBEC, a voltage regulator,
or extra batteries as the power source for your receiver. If you hear the music tone repeat
again and again for more than 3 times, you may need to check your power source to the
receiver.
·Phrases 1 Enter programming Mode
1. Connect your motor and receiver to the speed controller, but do not connect the
battery yet.
2. Turn on your transmitter and move the throttle stick to the full throttle position (full
up). Please Note: Most Futaba transmitters have the throttle channel reversed by
default.
3. Connect your battery and the controller will initialize with a musical tone.
·Phrases 2 Programming
After 3 seconds, the motor will start beeping a sequence of tones – a musical tone followed
by one or more beeps. Each sequence represents a parameter that you can program and is
repeated 3 times. The parameters are:
♪—
Music Tone + 1
Beep
Options 1. Cell Type and No. of Cells
♪— —
Music Tone + 2
Beeps
Options 2. Throttle Setting
♪— — —
Music Tone + 3
Beeps
Options 3. Brake Setting
♪— — — —
Music Tone + 4
Beeps
Options 4. Direction and Cutoff Type
♪— — — — —
Music Tone + 5
Beeps
Options 5. Timing Mode
♪— — — — — -
Music Tone + 6
Beeps
Option 6. PWM setting
Step 1. Starting, Enter Sub-optins. When you hear the sequence for the parameter you wish to
program, move the throttle stick to the Center Position to Enter Sub-options.
The controller will then start beeping a Morse code sequence of short and long beeps
representing the possible options you may choose for the selected parameter. See table 2 for
a list of all programmable options. Each option sequence is repeated 3 times.
Step 2. Select and save, the select the option, move the throttle stick back to the

Well after a slow build finally done with this boat. The motor's I picked were 2 suppo 3126 1600kv outrunnes from ben. Props to start will be counter CF40's and CF45's on 5s/6s. Esc's are seaking/Turnigy marine 80HV's.

Lookin good D. I ran my twin HOTR at 730 am this am. Ive got a malfunction in the esc. I went from 6S to 4S, figuring it would run somewhere in the 40s. It went about 30. Then all the sudden it woke up and hauled the mail, then slowed again. I noticed when it was running slow it had a strange ride attitude. the starboard motor was shaking violently upon acceleration and not reving out. It was only turning about 3/4 power. I tried another motor on that side and its still doing it. So its the esc. :ThumbsDown01:

I wish the water was warm here. It's cold as hell outside.

Ron I am starting with CF40's if the temps are good I will try CF45's. Depending on how that testing goes I will either get some x442s run as is or get them cut to x440s and or s447's as is or cut to s445. All depends on the results. I think the x442's will end up being the winning ticket like you said Tiq.

Got this thing in the water today and she ran good. Had some chop and a good bit on wind, but she handled it well. Gps said 53.8 which isn't that fast for a twin, but I was using CF40 props and temps where good, 110F on the motors after a 2.5m run esc was barely warm so I didn't even bother shooting the temps on it. Batts where 6000mah 25-50c nano-techs. Next test wil be with CF45s (big jump), I will only do a few passes then check the temps. Other than that I really enjoy this boat. Not bad for $19.99 motors...

I finally got a few runs w/ mine this past weekend on 4S. We are starting a 4S twin division at our club so my plan is to run this set up for now. I need to get it handling a bit better, its got some strange characteristics, apparently SAW set ups w/ cog etc is much different than oval running :laugh: But Ill get her dialed better than she is.

Heres a vid of the first run I think it was....

Yea I had the same problem. I almost rolled it going slow, so I turned the steering gain down to, and then even with the steering gain turned to 75% I did roll it lol. I may have to take it down further to say 50% but she looked so good, and those twin outrunners sounded awesome. I do have a small leak somewhere though. I will need to check that, I think it is coming from the right side sponson pickup. I had to epoxy that one in and it maybe leaking from the base.

GREAT vid and you had some good water conditions as well. What motors again? Nice Paint!
