I modified my Gryostick because I already had a good 35" diameter rotor. The weight however was 32 oz which is double what the original plan called for. I built it heavy and used an OS .15 LA. Initially, I kept crashing the model when I hand launched it. I removed the poly head and replaced it with Aerospace composite fiberglass hub plate. I never crashed it since then during launch.

I added more left tilt to solve my trim problem. My Gyrostick is very difficult to control. I can barely mange to fly it and eventually crash it.

I got my hands on set of Gyrostick laser cut parts. I am building a new one exactly like the plan calls for, but with a rudder control for ROG.

Do you think the heavy weight (double in my case) causes the model to be difficult to control?

Thanks
