I used the Protek 2300mah Lipo Receiver Battery(flat pack) with 7955 Hitec Servo's unregulated. The Radio I use is the Sanwa M11x. The 6T doesn't need much for upgrades, IMO I'd buy Aluminum Servo Horns, boil the Suspension arms, buy a High Downforce Wing and start racing. The truck uses 0 offset wheels.
