A head holding gyro is supposed to keep the tail locked straight in place. Which Im TOLD is very important for stunt flying. So theres no need to keep correcting tail drift, Cuz there is none.

Now this is what Im told. I have a new G90 HH gyro but Im still getting things setup and repaired so I cant say what it actually behaves like yet. I also only hover and slow FF right now, no stunt flying.
