Hello,
I am in the middle of a project similar to the draganflyer, and am looking to replace my practically useless pg-03s with a heading lock gyro. Unfortunatly, I have no channels to spare. would somebody point me in the right direction to a heading lock gyro (weight is not a major concern) that does not require a seperate gain channel to opperate. This craft is NOT mechanically perfect so i know that a gyro will not work at optimum, but it is pretty close.
Cheers,

A Futaba 240 gyro is a heading lock gyro with mechanical adjustment. It is the same size and weight as the 401 so it should be light enough to work on your project.

Futaba GY240 is perfect for choosing .A JR 410T is also the same to GY240 :single gain mechanically adjectment lightweight
