RE: stable, easy to fly profile
Yeh I know,
We actually did have a new flyer in our club two years ago that wanted to learn to fly and we put his OS 40 LA on an OMP FF540P and toned down the rates and off we went. Piece of cake and he liked this approach much better than the 40 trainer we also had. The FF540P was way more stable, much less wing loading, and no bad snapping tendencies. There was virtually nothing he could do to upset the plane.
