Thanks for the advice. This is my first truck and had no idea. I ordered the Hitec Aggressor FM Radio System with HFS-03MM and 1 HS-325HB Servo and Hitec HS-645MG Servo last night. Too bad it is not in time to keep my truck from taking off out of control to hit a fence post and destroy the front left wheel assembly. Live and learn I guess. Thanks again also for the fail safe advice. If any one is wondering about that go to http://www.ofna.com/failsafe-micro.html and read about it.
