@Snow, I love the RevTech motors, I have run a bunch of different motors from Viper, Reedy, LRP, etc... But I must say the best all around motor that I have used was the Schuur Speed 17.5. It is stupid fast, runs cool, and has more torque than most of the other motors that I have tried. Now I am by no means a pro this is just my humble opinion... Hope this helps...
