If they have a 300Kv., that would be ideal, but they have a big gap in their Kv's to choose from.

I was also thinking about a truggy center diff, but the Revo diffs are too high of a ratio to be used with one, you would need hybrid diffs.

Q1: What diffs were you using to blow the bearings? And how would an inrunner/trans setup be any different in that respect?

Q2: Simply, what do you think of the motor in question? Think it will be suitable?

If this did work, then the handling on the truck would be in short, sick. I would be able to keep up with truggies no problem, as I can keep up to most of them even with the high CG as it is now.
Q1. I was using the RCM v2 Hybrid Diffs. Difference = Direct Drive. No Slipper. Diff Torture Chamber!

Q2. Scorpion Motors are well built, but they have little or no fan. This makes it harder for them to shed their heat, especially in a rolling application. Flyboys mount them behind the biggest fan possible, so it works well.

Any Motor makes heat especially when pushed. If your mount and frame are aluminum, you might have enough mass to shed heat.

This is why I went with AXI. They do sell a fan that mounts to it's rotating endbell. It moves alot of air too.

I've been tempted to go with Mike's Slipperential. Put that together with regular straight cut gears in the diffs. An Outrunner geared properly would work very well.

For gearing, think outside the box somewhat. Go by the gearing calculator and even then, the outrunner has the torque to pull higher gearing than it suggests.
