I'm trying to get my first ArduPilot up and running on a TREX600. I've just flashed my APM2.5 board with Trad Heli 2.9.1 through the mission planner and I think I have everything setup right. Everything moves where it is meant to move.
My biggest problem right now is that I have to arm the helicopter via a laptop. With my throttle stick at zero (flying mode 1) in Normal flight mode, i can hold the rudder or aileron to either side all day long without it arming.
I have a feeling this is because my normal mode is set to -4 degrees pitch on the blades, with idle 1/2 getting full throw - but at the same time full motor power.
Is there any way I can arm a helicopter without my "throttle" at zero? If I switch to Idle 1 or 2 the motor is going to spool up to 75 or 85% which is, I believe, the opposite of what the Arm/Disarm is meant to be doing for me.
I have a Futaba T9CAP, with the pitch on CH3, and throttle on CH6. I've simply used the pitch curve for throttle, and the throttle curve for pitch so the channel assignments are correct.
Should I set a throttle hold mix to drop it to 0?
