RE: What Do You Think
You've heard this before...it depends on how you want to fly. That plane with the Magnum 70 four stroke flies well for sport flying; a friend at my field flies that combo. It does fly a little heavy and does not have unlimited vertical, but is fine for everyday sport flying. If you want more lively performance, a larger engine on that airframe will do so, but might also produce a higher wing loading and faster landings. My friend's already lands fast with the 70. Just my 2 cents. Jon
