Heli DDFP Tail Rotor Setup

Hi All,

Looking for some step by step help setting up a helicopter with DDFP tail rotor. Using a DJI Alpha 60A ESC and im not sure where the pwm ranges should be and just a good general parameter check before trying to fly.

I presume the min and max should be 1000 - 2000pwm but im not sure where the trim value should be.

When you arm and engage the motor interlock ( throttle hold) the tail rotor spins up immediately to the 1500pwm range ( i presume that is ). Main rotor is also spooling up on soft start value set in esc. Would this immediate ramp up force the heli to want to spin around on the ground before taking off.

Also the esc doesnt have an adjustable soft start value that i can match with the Castle Creation ICE main rotor esc. Is there a way in ardupilot to add a longer soft start to match the main rotor?

Thanks everyone for the help. Really Appreciated. Cheers
