I'm a G2 Baby!
I've learned a lot of plane flying with G2 and ALL (well 99%) of heli flying on RealFlight G2. I've never had a heli lesson and just yesterday my buddy made a comment about how fast I was coming along (FF, fig. 8's, stall turns, nose in hovering).
I think it's a great tool to learn new manuevers. I can flip, roll, & loop a heli in the sim. I think I'm just about ready to try it on my Hawk.
The sim is a great confidence builder too; I think that's half the battle.
