matador_24:: ... because I remember I read in a forum that "each time you reverse the gyro in the gyro, you have to reverse the gyro channel".
Maybe for a specific type of gyro but not for the 401.
Still not the same thing (s) ...
Reversing the rudder channel (ch4 for Futaba), reversing gyro channel (ch5 for Futaba), and reversing the gyro response (at the gyro) are three different things.
You already know what the first and last does ...
Reversing the gyro channel (gyro gain) might only reverse which side of the "servo" command is HH or Rate mode... which might affect which switch position equates to Rate or HH mode. Never tried it before ... seems to have always worked fine without having to reverse the mode/gain channel
