39" Mono, Castle 1717 build.

[Make-a-Wake]

Hey guys, thought i'd start a thread on my 39.5" mono, seems to be a few of these larger mono's being built for the 1717. It is somewhat of a DF41 knockoff and is well made in my opinion. Its gonna be powered by a Castle 1717 on 6s, with a T180 ESC. Hoping for somewhere in the low 50's.............

Some pics of equipment and progress. Thanks for lookin'!:thumbup1:

[blackcat26]

That's gonna be a sweet boat wake!

[Rumdog]

I had that hull in orange. Runs really nice! I used a Neu 2215 on 9s2p. FAST!

[Make-a-Wake]

Thanks Black and Rum...................great to know the hull has potential!

Got a little done today:biggrin:

[rearwheelin]

That looks like the hull I want to set the record with ! ............:laugh:
Very nice stuff, have fun building !
PS: I highly recomend doing something diffrent with the motor mount ! A crash will pop that mount loose or even rouph water.....:beerchug:

[JackBlack26]

Wow, that's going to be awesome!! Don't forget the video:thumbup:

[DISAR]

Very nice choice of materials (hull-motor-esc......) I use same layout too.

the support for the brass tube can be much smaller

I am wondering what propeller this combination can handle, especially the esc

[Make-a-Wake]

Thanks guys! Yes, i shoot more vid than a "B" movie studio, so i will surely throw some up by this weekend!

I have used my home-made mounts on 6 different boats and they have never failed..........i have a 1527 mounted on one in my 45" Avatar Dumas...............maybe i'm lucky, but i go with what works. I made epoxy flow holes in the hull mounts and they are quite long themselves.

I'm thinking of using either an x445......x447.........or x645, gonna start on the smaller end though.

[forescott]

x450 is on the smaller side but a safe option, and should net mid-50's for speed.

[JMSCARD]

I had that hull in orange. Runs really nice! I used a Neu 2215 on 9s2p. FAST!

I had the same hull too... sold it to b.mcdaniel... very nice clone... as rumdog said...

I ran mine on both a Lehner 2250 and a 2280.... both ripped.... I actually used a x445 with great results, ... of course I was spinning it at 38,000 rpm... I propped to a x450 for 8s..

[Make-a-Wake]

Any pics from those of you that have had this hull up and running? Sure would like to see 'em!

[JMSCARD]

Pics for ya.... this hull handles no question...

[Make-a-Wake]

NICE! Are you running 2p? I was thinking this hull could handle the weight of 2p myself.

[JMSCARD]

NICE! Are you running 2p? I was thinking this hull could handle the weight of 2p myself.

oh yeah it can handle 2p... and thats what I was doing... it could definately handle 6s2p... I was running 10s2p

[forescott]

here's mine......

[Make-a-Wake]

Thanks Scott...............nice! I see we have the same stinger and rudder except yours has two pickups. Do you still have it.........any vid.............top speed...........?

[forescott]

Yup! I'm getting low 50's from the leopard 5692(1340kv) on 6s and an X452.

CQ_IRxJjusQ

Heres another vid from youtube of a guy with a similar setup....

v-dnfyAlQwQ&NR=1

[Rumdog]

I sold mine to keithbradley. He posted up some vids a while back. I touched 70 mph with that boat. She was bad ass!

[forescott]

Rums build inspired mine. Still saving my pennies for a swordfish 240 so I can prop up!

[Rumdog]

Which esc are you running now?

[forescott]

Turnigy 180 w/rx pack. I know, I know :ThumbsDown01:

[Make-a-Wake]

Nice vid Scott..................i remember seeing that one before with the sound bouncing off the hillsides......sounds mean!

2 questions:

Do you think since mine is a 1580kv and a bit smaller motor that i should use an x445........447...?

Is my ESC adequate based on the smaller props i mentioned? Im not going for huge all out speed or SAW runs, just fun/friendly racing, so i was thinking a bit smaller prop, keep things cool and amp draw down a bit.

[forescott]

The 1717 has plenty of power to spin a big prop. However @ 35000 unloaded rpms a big prop is not a good idea. I think your in the ballpark starting with the 45mm prop. Thats probably barely enough diameter to get this big heavy hull on plane, but I know guys have used them with luck. Its a good starting point. I'm thinkin' that you'll end up with a cool reliable setup and a prop in the 47-48mm range. Ideally I think that motor will run better on 5s, with the 452. I'm looking forward to seeing it run!

[forescott]

I cant say enough good things about the t-180. It has a huge 360 amp burst rate, and I've been really happy with mine. Every esc has its limitations, but I think the t-180 might be slightly under rated.

[Make-a-Wake]

I own several T180's and have been very pleased with them as well. I run one with a Neu 1527 1y in my 45" Dumas and have had zero issues with it. I have heard the same thing about the conservative rating, that they are more like a 200 amper. In fact, I ran across this from G-freak(dont know much about them) "ACTUAL FACTORY SPECS ARE 180A CONTINUOUS AND 360A PEAK BUT WE RATE THEM REALISTICALLY, BASED ON OUR EXTENSIVE TESTING, AT 200A CONT."

Thanks, i'll throw an x445 on first................got a 447 as well

boy did mine get on plane with a x445... even weighed down with 10s2p.... was a absolute rocket, and no question with the small prop she carved.... handles very much like the smaller df's only BIGGER :)

I know I didn't think the x445 was enough diameter at first... but I spun her with some real rpms... mine (now brads) has a ball bearing strut too..!

[Make-a-Wake]

Got some more done, Looks like Darth Vader's rig............. :spy:

Kick ass, thank you!

[Make-a-Wake]

She's ready to go...........6s 2p. Got four 5000 40c 3s batts from the Hobbyking USA warehouse. 67 hours to my door from hitting the "place order" button.............16 bucks for shipping. I may use the USA warehouse as much as i can based on whats in stock there.

Two of the batts fit right up underneath the edge of the deck.......COG is at 30%.......

Gonna take her out in the next day or two.:banana:

[koontek]

can't wait to see the video! i bought 2 of those motors during the sale so this will inspire me to do something with it!

[Make-a-Wake]

Ran great. nice and cool!! x447 up next

D63jW7VT9JM

[blackcat26]

Nice! What are you propped with 445?

[forescott]

Pretty impressive if that is a 445.

[Make-a-Wake]

Thanks cat and scott.....................yep x445, i have learned the hard way to start out where i feel comfortable............seems to be working fine, but it can handle a tad more. I am not one to max out my systems cuz im not racing and lean towards cooler, more trouble free running. I think an x447/x448 may be the sweet spot.

[blackcat26]

I think a 447 no problem. After that work's slap a 645 on there and see what happens!

[Make-a-Wake]

I think a 447 no problem. After that work's slap a 645 on there and see what happens!

I have a brand new sharpened and balanced 645 i got for free from finedesign(long story):bounce:

[blackcat26]

Can't wait to see it in action. Those motors are proving to be a real power house! Check out the video section a member has a 23lb twin cat running those on 6s and it's killer!

[forescott]

I think that motor will handle waay more prop than you think. But you are doing the right thing by taking it slow. Props testing can get expensive if you start out too small though. I run a 648 and 452 in my 40 w/leopard 5692 and it doesn't even break a sweat! Lookin good!!

Yep, thats my good Buddy Bill and His "Goldfinger"...................i called it an oil tanker cuz of its weight:bounce:............ , he really has it going well........he's just gotta get the nose down a tad.

So.............im thinking i throw the x447 on for my next outing and go from there! Thanks guys for looking!!:thumbup:

[Brushless55]

Looks good man!
I'm very tempted to try one of these motors in my Baja 5B!

[Make-a-Wake]

Todays vid.................quite pleased, temps still insanely low...............guess a 645 is next, should get me to 60! EDIT: this run is with an x447 up from a 445 in the previous vid. 53.5 mph gps'd

S1azvpBRH1c

[Brushless55]

sounds good

[DISAR]

do you have any offset on the shaft to the right or it is centre?

it runs very well, seems like it can handle more speed

[Alfa Spirit]

Very nice boat, what about torque effect? I' building a 39" MHZ with the same motor. I will try 2 rudders and Speedmaster stinger. Too much torque for a 39" mono? Thanks

[Rumdog]

no way Alpha. I ran that hull with a Neu 2215 on 9s and a x457 with no torque roll issues. She's a biggin!

[Make-a-Wake]

No offset.................

What do you alll think of trying an x645...........went well with the 445 and 447............seems like a 645 would be next in line.......

I'm concerned about the T180 ESC. Thoughts?

[blackcat26]

If your motor and speed control are low temp'd I would step up and try the 645. Do a few passes and bring her in and check everything. A 447 actually has less total pitch than a 642 does. If it was me I would try the 645. If that looks good I would prolly skip the 646 and try a 648.

[Make-a-Wake]

I have a 642 and was thinking that would actually be a slighter step up from the 447.........but the dia. is pretty small..................so 645 i guess............

[blackcat26]

I always refer to the prop section on this site and look at the numbers to make my prop decisions. Now put the 645 on there and kick it!

[rearwheelin]

Awsome ! $90 Speed controll running max volts in a 39" mono. I am 110% sold on the 180's !

[Make-a-Wake]

Thanks rearwheelin'................. I own several T180's and they are darn near bulletproof. It has been mentioned that they have tested at more like 200 amps constant. The BEC's have always worked..............

I threw my 645 on but the prop hub is smaller than the 447 hub so it looks goofy with the big drivedog...........no smooth transition.......and the hub is shorter too. Gonna order an x450 and probably use it as my final choice as it 'may' hit 60mph, i'm more than pleased with the solid, cool running setup and im not "racing" anyways.

I have modified aeromarine drive dogs with a dremel to fit smaller prop hubs, there drive dogs are 3/8 o.d. and strong.

[Make-a-Wake]

Ok.........finally threw the x645 on. Still got a bit of tweaking to do...........there's a bit left in it i think.

Vid edited down to save time, think i got the top gps pass here.


T2tb2z2REDM

[Brushless55]

is this the biggest prop yet for this setup?

[Make-a-Wake]

Yep. so far..................i think a may try an x450-452 for more diameter though.

[forescott]

I have an x-452 from my osprey build if your interedsted.

[Make-a-Wake]

Hmmmm.............Sharpened, balanced...etc...............how much? Thanks!

[forescott]

Sharpened and balanced by me. I'm no "eggneg" But I do have a nice balancer and a good set of files. I've already run this prop a few times in my 40" osprey. It runs real smooth. I'd only ask $15/shipped. LMK!

[Make-a-Wake]

Well..............the x450 is the "cheese" for this hull........... :thumbup1:

Missed 60 by a HAIR..................59.4. A little windy so i should get my big 6-0 on glass!!

I'm pumped........this 1717 is a PIG!!!

[rearwheelin]

Nice !

[Make-a-Wake]

Thanks Rearwheelin'! Had a couple of other forum members there btw to "witness" it since no vid................temps on motor 92*, ESC 101* and batts 85*, ambient air temp 68*

This motor continues to amaze.......................heck, it may take an x452 :bounce:

[rearwheelin]

Perfect setup ! What was temps before you started......Its so hot here where i live in the summer that I am allmost screwed before I even get on the lake....lol...I pre cool with ice water using a weed sprayer now :bounce:

[Make-a-Wake]

Do you mean air temp?...................68* if so..............

[rearwheelin]

Air temp is usually close to ambiant temp depending on how long its been sittting out side in the shade...lol, I was just curiouse to how many degrees everything went up....Its in the 100's alot durring the summer here and from some of my setups that have worked for others in cooler climates don't last too long here when its hot out...lol....I think yours would fly here, I would still pre cool with ice water though...........

[Make-a-Wake]

Are you in Bakersfield, or near there???

[rearwheelin]

I go to Bakersfield to run.....I am about 30 miles wesr with no water to run on.........There are only 2-3 pond I can use in Bako..

That's really good news. I suppose it is with the T-180? Very good!

[gerardobrandao]

Yes, with the T180 Disar.

gerardo...............did the boat ever come back up?????


I´m doing 62-63mph with an X452 prop, detongued, and cupped...


When the boat drowned i waited 2 minutes to check if the boat would come up, or not...
After a while a sympathic gentleman asked me if i would like to use is real boat in order to find the boat.....
I searched 10 minutes long and didn´t find anything!
Altough is son, checked some red from the bottom, so i dived in to 13 feet water and found the canopy....:ThumbsDown01:


After a while, the son again...told me...check that out,the canopy was 50 feets away from the hull :eek::eek:
Dived again and retrieved it..The only damaged thing was the turnigy bec....:smile:
here goes a pic...checkout the canopy completely broken..:thumbup1:

[chummer]

Had a couple of other forum members there btw to "witness" it since no vid................temps on motor 92*, ESC 101* and batts 85*, ambient air temp 68*

This motor continues to amaze.......................heck, it may take an x452 :bounce:

Any idea how many amps you are pulling? How long were the run times with the X450?

[Make-a-Wake]

Thanks guys. Chummer, i have gone back to an x447 as the x450 thermalled the ESC as water temps rose here..............it was maxxing it out. I was able to get away with it in the 38* water............now into the 50*'s i have settled on the 447 as my summer prop. Ran today in fact, ol Vader is just a treat to run................never a problem, and runs smooth as silk on the last 3 inches of the pad:thumbup1:

Threw a GPS in it today just for kicks and got 55.6 in small chop with th 447.......................plenty since im not racing for pinks or trophys, gathers quite a large audience at the lake as well.

Runtime today was 5 minutes easy..............mostly WOT..........loooooong straights and sweet carving turns. Cells were 3.85 when done, so i had another 1 to 1 1/2 minutes left. Not sure about amp draw, im thinking its in the 130-140 range. This hull is the biggest bargain i have found yet in a mid sized mono.:thumbup:

[Brushless55]

Awesome, thanks for the update! :rockon2:
I have a X645 I may try on my Thundertiger OBL with this same motor :thumbup1:

[chummer]

Man,,,that is sweet. A 5 min.+ run time @ 55mph with at 39" mono on 6S with a Turnigy 180. Very nice setup. :buttrock:

I have a HK Vanquish hull on the way, not sure what I will power it with yet. I was thinking about the Leopard 5692 on 8S although I already have a Hydra Ice 240 and I am waiting on a 1717 that is in transit.

Hmmm,,,,,So many options,,,,so little money.lol.:olleyes:

[Jacked1]

I was wondering if that was a Promise Hobby hull? It looks awesome :thumbup1: and I think it would be prefect for my inline motor idea.

I don't know what you have up your sleeve but if you are looking for a hull that size then you might want to consider this one.

http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=15235

It will cost around $50 to ship it but it also comes with hardware.

Here's one......................click on products, brushless motors etc................

http://www.kershawdesigns.com/

[Brushless01]

Wow nice build man thinking of building one of these with the exact same setup got a few questions though what rudder and turn fins did you use and also how far from the transom is your motor mounted and what prop would you reccomend as the best all rounder ?
Thanks

[Make-a-Wake]

Hey Brushless, I ran that setup for quite some time but have actually gone to a Neu 1527 1y on 6s2p. I live in the southern US and it stays over 100* for weeks on end in the summer. Water surface temps get quite high in "non flowing" lakes and I was always fighting my temps. Unfortunatley i set this boat up in winter and would have had to prop down quite a bit to run it in thie summer heat without the ESC thermaling which it did a couple times. I run a a T180 and wanted to stay with it so I simply pulled the 1527 from my 45" Dumas "scale"skiboat and threw it in. This may sound lame but it also fits the whole "Vader" thing being a long black motor and looks nice in it. I can now run an x450 all the way thru 10,000 mah with zero issues and it is still over 50 mph, granted not 59, but its plenty fast and i'm not racing anyone really. I am starting to tone things down a hair in my setups to allow year round running.

The 1717 on 6s is a sweet setup for sure and i obviously could have thrown an x445 on it but this is just the way i went. In your climate i would imagine you could run the 1717 year round with an x448 or so and have a super boat! Now i have a 1717 for some other project if i need it too.

I used this rudder and these fins:
