I finally got time to assemble my flybarless 450 trad heli, I swear sometimes Hobbyking is slower then monkey spit rolling uphill. And I bought the Assembled APM2 with out GPS back in June, it arrived July 10th.
I hooked up everything per the wiki and the discussion here. Installed the correct firmware for Trad Heli. and calibrated my radio. I pulled the main rotor, tail blades and started testing and all I got was throttle with no servo movement. I checked my Throttle Pitch curve 50 50 50, So I adjusted to 0 25 50 75 100 on both throttle and pitch. Still nothing from the servos. I pulled the APM and added JP1 hooked it all back up and still nothing. I charged up the little 1 cell battery that I use for radio setup, applied 4.2v to the servo rail on the APM with jumper 1 removed and there i got servo movement. I don't have a working multimeter at home so I was unable to check voltages.
I am using a 80 amp Turnigy Super Brain for my ESC, Overkill I know but it has so many options that even the options have options. It is governed with data logging and a hefty BEC BEC: 5V/4A (Switching BEC, supports above 4 digital servos). That provided exactly 5.0 volts. I performed the mechanical setup with out the APM installed and all 4 servos are good and move properly without the APM installed.
I have the blades set for 0* pitch at 50% swash throw and perfectly level.
I am using 3 x Digital Solar Servo D220 for my swash, and 1 Digital Solar Servo D221 for the tail rotor.
Is there a separate step for digital servos? Is my APM defective?
