I think you just spelled out the exact problem I have. I roll too far to turn left then I over react and roll too far to the right. I end up oscillating back and forth and eventually making a hard or crash landing. I don't think I have stability problem.

I am building a ECDC gyro and it’s almost complete. It will have rudder control and rotor tilt for lateral control. It will not be a full DC because I will us only the elevator for pitch control.
