Through in my GTB with 10.5 in my TC3 today, and was playing around on the street. Man, what a rocket! This is my first brushless set up. What an upgrade from the Novak Cyclone and 27t motor! The run time was rediculous with the brushless! I was getting bored out there! Hahaha. Now I need to find a 4.5 brushless and a 7cell NiMH and then let the games begin!
