RE: How does a Gyro work on Rudder Application?
My two cents is that if you do not now fly coordinated, that is rudder with ailerons ALL the time, you are in trouble with twins and particularly the P-38. In an engine out, then is NOT the time to learn to fly with the rudder. The gyro is invisible with coordinated flight. Loops are much more straight. If you set it low, as you propose, then it will be of no use in an emergency.
Rolls are really not affected, as I have two gyros on both of my P-38's, except that they stop NOW!.
Please do not misunderstand, I am not trying to beat or cut you down, but I want others to avoid the mistakes I made and enjoy twins.
Are gyros a necessity, no, but good insurance.
Good Luck,
Twinman
