Im using the JR 9000T 320 oz. of torque and had was having problems with the aluminum servo arm bending every time I raced. At first, I thought it was t-boned by another car on the track so I installed the plastic side guards to protect the arm. I raced it and once again, the arm was twisted. It turns out the the servo saver was too tight and the torque of the servo was bending the arm if I landed a jump crooked on the front wheels. I'm impressed that a years worth of beating that servo and it hasn't stripped out the gears. You really do get what you pay for.
