if you order the ball bearing set and install upon assembly just replace the stock bearings with the ball bearings, its a very simple process. also a motor is a must the stock 540 just doesnt cut it...i first upgraded to a venom 21t and quickly realized this as well wasnt cutting it i recomend the reedy quad 18t by associated. any more questions on your tt-01 just ask.
