I am currently finishing up on my Hangar 9 Edge 540, and i just bought a Futaba 9CHP radio............. I am going to use the 9001 servos on the aileron's and throttle but dont know what i should use for the elevator and the rudder. I was thinking about using the Hitec 645's? I know that you want at least 100 oz of torque and its at like 107 at 4.8 but the speed is at like 24? will that be too slow for 3D?? I am mostly going to be hovering, etc. Plus should i use 2 servos each on the elevator and rudder?? And heres the next question, would a Brisson 3.2 be more than enough power to hover all day, and still launch er up like a rocket?? I look forward to your guys' comments............ Thanks a ton everyone is always so helpful!
