traxxas villan build

[20psinow]

well guys i gutted the boat and down to a bare hull.. just pick up some stuff at the hobby store and gonna start this weekend converting to direct drive and 3/16th prop (aquacraft 40x53) and moding the stock motor mount and useing the stock drive line.. its not ment to be fast just a fun weekend thing and give me some thing to do the rest of the winter .. the 20 turn, speed controler is going back in and going to run 14.4volts to one motor hehe ill probly somke something buy the time im done but just gives me reason to go BL and lipo.. i post pics latter on..

You will definitely smoke and pretty quick! The beauty of twins is to reduce the work load by half to each motor AND they were geared 2:1... I have been there - I got about 18 seconds of 40mph from one of those Titan motors direct drive in a 26" mono on 4S.

I would get one of the Aquacraft or Proboat motors/escs and use that - you should be able to pick up a combo for under $100 with the right timing.

Unless you are not looking for speeds over 20 mph - then you may be ok

Traxxas once converted this hull to brushless using two of their very own Velenion brushless motor/esc systems. I think the boat reached mid fourties mph. The artcle was in a past issue of Radio Control Boat Modeler.

anything around 20 mph will do just fine.. i ran it last summer on 7.2vol with is geard 2-1 and it ran for 25min.. thinking if i just run 7.2 on the direct drive it should be ok.. proboat motor and esc would be nice but i have no money right now so im useing what i have laying around. were you on lipo and what boat were you useing? O and last summer it ran maybe maybe 6mph with the stock prop... very slow but would get up out of the water nice...

see BL is the last thing i want to so right now due to the cash flow but latter on maybe, what i would really like to do would be go and get a mhz hull and make a scale boat with scale drives on it my dream.. but for now just got to work with what i have

[Jesse J]

you can always ducktape some estes rocket motors on there...

Steve sells an upgrade kit for the Villan, It uses two 447 props.

I think thats been out of stock for years.

what about upgrading to a johnson drill motor. i did in my villian and they worked pretty good!

[bwells]

Don't bother with the 447 upgrade, maybe 2- 3 mph for 70 bucks once sharpened and balanced on your own and I think that is why he discontinued it. I added the coiling coils as well but the biggest improvement was with 4s. Mine is stock except the props, cooling coils and lipos but have not GPS'd it yet. Totally unsinkable and unflippable (no swimming involved) and my guess is 30 MPH

Don't forget about these:

http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=6678&Product_Name=KD36-74-09XL_1900kv_Brushless_Inrunner

You can add a watercooling plate to the esc. Search for it, there are a few threads on it.

ok i need help.. if i do the inrunner with the esc will i be pushing 80amp? or is that what the motor can handle? i dont know how to read the kv's and i dont know what how to find out what amps im going to need... i stupied when it come to electric stuff but making things work im golden

[20psinow]

striped boat hull so far going to wash it all up to night and start this weekend.. need to find out more info on going to lipo and that inrunner but that may be the next step..

The hull doesn't look that bad!! I'd cut it about a half inch below the top of the cockpit area, or wherever the hatch mounts. Cleanliness will play a big part here in how good the boat looks (mark the cutline first and do many light passes with an exacto knife. Sand the edges smooth after you cut so you don't cut yourself on the edges).


Kv= RPM per volt. If you are running 12 cels, or 14.2 volts, you will get about 25,000 rpm unloaded.

This motor is also very torquey because of it's size (about 2 'standard' 540 motors placed end to end) and will be able to turn a large prop that will push the boat to speeds very quickly.

Electric motors only draw what is needed. That motor spinning at full tilt with no load will not draw but a few amps; 2.6 to be exact. It's a good estimate that a 540 xl motor will draw about 80 amps peak on a sport setup, so the 100 amp esc gives a small amount of overhead for fast accelerations and insures that the ESC is not being run at it's peak current for long periods of time.

The motor and esc on your current batteries can give you a nice, stable running sport setup with speeds in the mid 30s. If you want a more reliable setup or don't want to have to watercool the esc yourself, i'd use this:

Your batteries should be fine for now, but you will want to switch to LiPo's eventually.

However, the first order of business is getting you a hardware setup... How much do you have to spend exactly?

[20psinow]

well right now i have a hull, stock hardware, some unknow brand hardware, the metal prop, and stupied little thing hear and there but id say buy the time all sad and done 150ish at the most right now. would like to keep it in the 20ish range but the amps, volts, load blablabla i dont know what im looking for.. would like to stick with the ni-cd's and run 14.4 volts but the rest i just dont understand how to pick out..

[j.m.]

You can use a carbon Graupner 40mm prop on this driveshaft:

According to FE calc that will get you to 40mph, but IDK about that. Low amps though, says 36 amps constant. Very low for a boat of your size (I.E. Efficient).

Try to keep the shaft at an angle as close to parallel with the hull bottom as possible and use this connector:

I'll draw a pic and attach it in a bit...

Then do something inexpensive for a rudder and I think you can easily meet your budget and keep you current batteries. :D
