I have both, and G3 is all I use. For Heli's, I find G3 as close to RL as any. Reflex was supposed to be #1 for heli's, but G3, TO ME, is as close as it gets. Planes in G3 can be tough, but what are you going to learn if it's easy. I was disappointed at first in the planes at first, but now that I can FLY, I really think it has helped. AeroFly was fun, G3 is a learning tool.
