Most guys are all over with this one. A Savox 1258 or a Spektrum 6040 would suit the needs fine. Both spec at 167oz/0.08sec. Several run Hitec 7955 which is 333oz/0.15sec. I was running a Orion 1409 (200oz/0.10sec) and I never was short on power or speed. For the heck of it I recently put in a Protek 130ss (211oz/0.06sec) in my truck, and DAMN! Servo is incredibly quick and powerful. If I wanted to I could crank up the voltage to 7.4 volts with my Viper VTX8 and the specs at 7.4 volts are 260oz/0.05sec. Any servo that specs in the ballpark of any of the above would put a smile on your face.
