Direct Drive to Diff E Revo Build

[sikeston34m]

I thought I would show you the difference in the Outrunner used in the E maxx 40mph setup (direct drive to transmission) and the AXI 4130/20 that is going in the Revo. Big Difference!

It's the only one that I see with a 515kv rating.

I believe so. I will check it and get back to you. It is not here at the house.

That motor has alot of use on it. It started in a twin rotor helicopter, then it proceeded to run my truck, now it is running the head of my Taig CNC. :)

I love outrunners.

Here's a few pics of the progress. Still in it's rough form. I plan to line the lower part of the battery tray with the "loop" side of some velcro. This will cover up the counter sunk screw heads and help protect those precious Lipo's.

Made some more progress tonight. I took it all back apart and used blue loctite on everything. Now all I have to do is figure out how I'm going to mount the receiver and the Quark Esc.

I have a Servo Tester. Little box with a dial on it that will control an ESC also. It duplicates the PWM that normally comes from the receiver.

Anyway, I couldn't resist hooking it up to 6S A123's and seeing the tires swell. They really do swell too. LOL These tires are REALLY out of balance.
I think this one is going to get the Phaltline tires with the Blast wheels that I've been saving. I originally bought these for my E maxx, got the aluminum wheel hub adapter kit along with them. Are the Revo and E maxx hubs the same? Will they work?

It's a good torque monster, I think the high gearing just might work without cogging issues.

Does anyone have suggestions on mounting the esc and the receiver? Perhaps some mounts that extent over the shock in the front and rear. I would like to keep these in the center of the truck. This will save battery compartment room for some high voltage setups.

Just make a little plate on to mount the ESC on top of the motor. Receiver can go on top of the ESC, or on top of the steerings servo (or opposite the steering servo).

Looks good - I look forward to seeing a vid.

Excellant Idea BP!!!!

I can use 4 PCB standoff's just tall enough to give me good clearance directly over the motor. Then I can mount an aluminum plate on that. The plate can be up to 2" wide and 6" long! I'll put them both there!

What would really be nice is to find a heat sink of the right size. Use it for a plate. Turn it upside down and let the motor fan blow on it. On the top side, attach the ESC to it with some thermal compound.

During my test run, I let it run at full throttle for about 5 minutes. The Motor was cool as a cucumber.

Hmmmm..........the possibilities.

PS..........let me get it perfected and I'll get some vids. This should be good.

Here's a few pics. The Motor only stick up about 1/2" out of the frame. I think there is enough head room there.

Dang man, that looks soo bad ass. That thing would be SO quiet... but then again, it's kinda nice to have gear noise as well! THere would still be diff noise, and tire noise as well...
