I think Landing on grass is something that comes with some practice for sure. A plane with the landing gear very close to the CG will be tough to take off from grass and really tough to land without nosing over. I have a Dynam P-51 that almost needs a pane of glass to take off on. For a new pilot I would recommend the FT Spitfire with a prop saver. Then once you've gotten the hang of landing on the belly, go for something more like the FT Mustang. Don't be discouraged! The guys I fly with all found grass landings to be something to work on but if you keep at it, it will get easier. Personally, my problem was trying to time the stopping of the plane with the landing of the plane. As a result, I would always come in too slow. Good Luck!
