Please help me understand how the rudder/gyro setup works. It is somewhat of a mystery to me.
I will summarize what I think is the right way to set things up. Please correct me where I am wrong or have made some bad assumptions. I have a Futaba 7CHP radio, a Futaba 401 gyro, and a Futaba digital servo.
THE RADIO
1) CH4 (rudder) should be set at 100% for Dual Rates and “0” exponential (this means no dual rates or exponential for the rudder). End Points should be set at 100% Left & Right because travel of the servo arm is adjusted using the limit trimmer on the gyro itself.
2) CH5 (gyro) End Points should be set at 100% because gain is adjusted in a separate gyro menu on the Radio.
3) The Gyro Menu is used to set the gyro mode (HH or N) and gain to an assigned switch. This is so you can have different gyro sensitivities in each flight mode, i.e. normal vs. idle-up. The lower the sensitivity the quicker the tail will respond to stick input.
THE GYRO
4) DS Mode switch to ON (because of digital servo being used).
5) Delay Trimmer to “0” (because of digital servo being used).
6) Limit Trimmer adjusted so the servo arm will have full movement but will not move enough to cause binding. This will control the speed of your pirouette.
