RE: Gee Bee
The Page 1/5 scale will slow down to nearly a walk (if built and powered as recommended) and likes landing better if there is a headwind which helps keep it from nosing over. Other than the nose over tendency it is a truly nice flyer, very stable and it goes where you point it. It flys quite a bit like an extra, cap, edge, etc.
I have the 1/4 scale under constuction and look forward to similar performance.
If you build one I would suggest some LIGHT reinforcement in the rudder/fin area to strengthen it a bit against a nose over.
ie some carbon fiber strips or 1/64th ply to strengten it a bit in the vertical.
