If you do run it, junk the AA holder and get the 7.2v pack. The AA's ran down in about 15-20 of running and then it was just painfully slow. Just changing that battery made it a whole lot more fun to drive. But it's still not enough zip so we're looking into the Trinity Mass Termination motor. For $25 it's a quick upgrade that works with the stock Rx/ESC. We'll let you know how it works out.
