I have a G2 and also the copilot. Warlock is right in some ways about sim. If you dont have enough computor the sim is no good. It takes a pretty good computor to make it seem like flying RC. The copilot on the other hand will get you hovering. But you have to have somone set it up or you will never get it to fly. Everybody has there own oppinion. I will keep mine to myself. I have both and they both are a very big help. But all in all you will not learn to fly with out a crash or 2. So be prepared. The rappy is a cheap one to fix.
