Calculated motor specs/recommendations

[BrianG]

Sounds good to me, if geared a tad too high. Unless this is specifically for high speed runs, a truck running at 47mph is a bit hard to control. I would gear for 40mph max, but that's just me. And since you're running a Neu motor, you could actually move up to 6s on that same motor for a little extra speed. Of course, the Quark may not run 6s, but I'm just thinking of future upgrades.

Depending on your upgrade timeline, you may want to wait until the MMM comes out. It will include a motor based off the Neu design and be a 6s capable controller out of the box for ~$300.
