I have run the Rustler a few times since the motor uprade and the wheelie bar does get a good workout.....if I go WOT from a stop it wheelies, if I get a slower rolling start its not to bad, I have heard that you can use a Revo spur, I think I will try that, I will just have to get some mod1 pinions. I do like the 32 pitch gears though, I have noticed the Feigao 9L has been running cooler thean the stock VXL motor
