I built my second Gyroshtick exactly like the plan suggested. I used the recommended engine and kept it light. It primary controls are the rotor tilt system with no controls in the rudder or elevator. I still have the same stability problem as my last heavy Gyroshtick. It is handful to fly.

I am in a process of adding rudder control. I am planning to use less rotor tilt control and use a lot more rudder for lateral control. The rotor tilt control will be used to trim the model.

Would adding more rudder control help my stability problem?
