notice that i put Best in bold above, i didn't say it may be optimal for servo life but that is the best setup for tail performance. i don't fly for life expectancy, i fly for performance, the ability to hold the tail regardless of what i do or the attitude of the heli and that can only be accomplished with a near max gain (with the 401, the 601/611 or the JRs are different). if a much lower gain works for You then by all means use that. i guess for my flying style i should replace my 401s with the JRs but $$$ is a determining factor there. also your Futaba radio may work differently (but i doubt it) the piro rate is determined by the ATV (end point) of the rudder channel. this is a rate Demand gyro, rate of pirouette is determined by the demand (your stick input).
