I guess I forgot to post some of the facts, The motor is a Neu 1515 2200kv and the bats are the new Max Amps 4s 4000 Mah. I'm not running any fans right now on the Quark, it would probably make a difference though. The battery trays were one of the hardest parts to figure out, because the pinion is so close, but they actually work very well. I've been in some wrecks and no movement what so ever. The velcro makes all the difference.

I'm happy with the speeds so far too. Even if I gear down a tooth it seems like it will still be very good.
