Credence. Let me ask you this. If you just wing it with your setup, and in HH mode the servo ends up off center to hold a hover at say 15 degree's left, do you think you are helping your servo and setup or would it be better for it to be set to zero to hold in a hover? Take the time to do the mechanical trim and your servo will be happier, you will get better peformance and your servo will last longer.


Ace I've set up a buncha helicopters, from no gyro to avcs. Everyone I set up, once you get the tail stable in rate mode you can fly it around without the tail kicking around w/o revo mix. You probably can't punch or chop the throttle but I dont try it.

After that set it to HH mode and forget it. You dont have to worry about heading hold mode failing in flight. Either the gyro or the servo is going to go or its not. In either case it will be over before you have time to pucker your butt cheeks.

Throttle to rudder mixing or REVO is all the same thing. An attempt at mechanical or electronic mixing to automatically ofset torque by giving more or less tail rotor pitch when the power setting is changed.

As to your sim dilema, if you have wind turned on, a rotor system is more efficent with wind blowing over it then not. If you catch a gust or turn into the wind the heli will gain lift and go up, if you turn down wind, or compensate for a gust then the wind slows down or stops, the heli wants to drop until you get the power back on.
