10s 36v motor am I crazy ?

[xCoolHandLukex]

Bought a brand new 36v dewalt about a month ago. Was installing some lights on a dozer today forgot my drill on the track and crunch I'm out $300. But sliver lining the motor is undamaged. So I was thinking I have started collecting parts for an 8x8 project. Was going to run dual 14v dewalts but what about a 36v motor on 10s ? It's going to be heavy but that's what I'm going for. I searched but couldn't find much on setups like this in anything but on road RC. Anyone try this before ?

never seen it done. but heavy, 8 wheel drive, and 10s makes for some serious pulling power. finding an esc that can handle that power might be difficult

What is the C rating for the Battery?
What is the max amp rating for the motor?

I can get up to a 100c off the shelf there is a local battery shop that will build me a 250c custom. From what I can find the stalk rating of the motor is around 300 amps

ESC is doable

A boat ESC was my thinking too. Since weight is no issue the required water cooling should be just another "cool" feature on the truck!

Build it. Video it. Be a legend.

What kind of drivetrain do you expect to use and be able to handle the power???

100c = 100 Amp

So 36 v x 100 = 3600 watt peak power!

3600 watt/746 = 4.82 H.P That is a lot of power

----------------------------------------------------

36 v x 250 = 9000 watt peak power!!

9000 watt/746 = 12.06 H.P .....Not needed at all

----------------------------------------------------

I am thinking a 50C battery should be enough. Then two its peak power will be 2.4 H.P

Operating voltage 12 - 63 V
Max. continuous current (for full throttle) 400 A

Your not crazy, its ingenious.

I run the 250 amp version on 12 cell (5000mah 65c thunder powers) in my Losi 5ive...never even gets warm.

Haven't got as far as axles yet so far I have
36v motor
The square tube for frame rails
4 x 7954 servos
6 channel controller
8 x 2.2 pitbulls on axial rims
I've 4 different sets of 8 shocks see what fits best after I build the rails and decide on axles.
I like the idea of the marine ESC and using a radiator to cool it just for cool points. This thing is going to be geared low because of weight so I don't think heat will be a big problem.
I really need to find a body before I go much further.

This rig is gonna be AWESOME!!!

100c would equal 100a only if the battery has a capacity of 1ah. I would guess in a rig this size 10ah might be more realistic. A 10ah 100c battery would be able to produce 1000a.

Not knowing the ESC, does it have/do you need:

-Instant reverse?
-Drag brake?
-Is it brushed, brushless or both?
-Is your motor brushed or brushless?
-Is the ESC programmable, if so, how?
