I finally finished my nitro to brushless conversion of an HPI Super Nitro. I was looking from something larger than a normal 10th scale to tame a MM 7700. First things first, I had to make a mount that I could attach the motor to that would mesh with pinion. I started out with some very stiff plastic, but ended up using it as a template. With some aluminum angle I fashioned up a mount that allowed the motor to sit low in the rear and mesh with the pinion.

After ruining a lot of angle I got it right and in went the Mamba. Ran it on eight cells first and it moved but not to my liking so I went with a 6.6V 2S1P A123 lipo. Did a lot better but I ended up killing the A123 by over amping it. It was rated @ 66A but the Mamba can pull upwards of 100A.

After a little more research, I picked up a Medusa 36/60 3100Kv motor and a couple of zippy lipos, cut yet another motor mount and rear brace and finally after a few months of dedicated work, it finally runs and well.

Here is a video of it on a stand

That's pretty cool
Do you have a front one way?

But why did you go from nitro to electric??

Big House

yeah the front is a one way and I have never been into the whole nitro thing. It is messy and you can test or run everywhere. I ran it today and it is a sticky rubber drifter. The new Medusa is amazingly torque. When I give it throttle the back end drops. Still have a some work to go be it runs for now. Will need foams to get the speed out of it.

What tyres are you using on it now?
Foams are almost impossible to find in that size
