Another Brushless REVO conversion

[Serum]

Looks great Shark!

Nice motorholder; looking at the edges, is it lasercutted?

You might need to support the motor to keep it from flexing.

Kyosho batteryholder enable you to hold 7 cells per holder.

Hey Very Nice!!!

Love that motor mount. I was thinking about doing something like that but never got around to it. Do you by any chance have the drawings or a CAD file for a that motor mount? Id love to make one for myself.

The motor mount came from a fellow rc monster poster, his URL is www.eaglesviewaerial.com/products.html and he does fantastic CNC machining in metal and carbon fiber.

When I first got his mount I installed it as is, with none of the stock REVO motor mounts. There was a ton of chassis flex, so I decide I needed to also use the stock nitro motor mount brackets and reinforcement brace. I had to mill the nitro mount flat so I could bolt the brushless mount on top of it. Then I added the extra Traxxas reinforcement plate and bolted everything together. After all of that there was no flex at all, but I agree that a motor brace (rear or mid) would really bulletproof the mounting. I think I can machine a small "U" shaped bracket that can fit under the motor, which I can bolt to the mount. This should provide good mid/rear mount support for the motor.

His name is b0gh0s. I was going to have him custom make a motor mount for me for my Revo, but he got too busy. His current mount wouldn't work with the XL motors because they were too long and rear wires would hit the suspension arms due to the mounting height of the motor.

It Lives....

Last night, I mounted the motor and ESC. I moved the battery trays lower, hooked up the brakes and put the tires on. If weather and daylight permit, I will give it a run today. Also, I will try to find my scale and see how heavy it is.

Completed chassis


Wheels on


Which one is fastest?

Shark, glad you liked the mount.

Sorry I haven't been around much, primary job has been killing me.

I'm not following on the chassis flex issue and I'd like to better understand what flex you are seeing there. It is probably something easy to fix with the right cross bracing.

I have a few updates to the kit I've made including a mount that moves the ESC up over the rear shocks where fans can get some air (close to the cooling holes in the nitro bodies on the Traxxas lids). When I get a few run off you and the others that have bought get free upgrades (just pay for shipping).

Can you shoot pics and maybe point out where the flex it coming into play?

I've had ZERO issues with the setup flexing on mine but I might not be pushing my machine as hard as you guys do, I just beat around the ramps at the skateboard park near my house and in the front yard.

It's been awhile but I seem to remember that your mount bolts directly to the Revo chassis without using the stock Revo nitro mount. In that configuration I was seeing some flex in the chassis. The Motor kinda hangs out there on two thin pieces of aluminum, and without the nitro mount to tie the motor/mount to the main chassis/diff I was seeing some flex in the chassis (between the motor and the main chassis). I modified the nitro mount so I could use it with your mount and no more flex. Your mount is still going strong and I have a more powerful motor on order. Yeah the tray over the shocks would be great, I am currently running my ESC over the front shocks, but I would prefer it in the rear. The only issue is the Novak ESC with its built in fan is kinda tall.
