losi24,

Those servos are too small for this application. My Hobbico CS-35 Mini Servos have 55oz-in torque. It's basically a 2/3 weight standard servo. Use an HS-81 as a minimum or preferably an HS-85.

RD55,

Yes, I had no doubt that your Phasor 30-3 was a good selection. We only disagreed on it's power source. Note that my Kokam 3.2AH pack can deliver 64amps and I only draw 25amps at full throttle. Nothing in the power system gets stressed.
