I have made a really good discovery with learning to fly!!!! its called the pucker factor!!@! If im on the simulator and just dont think I can do even moves the good flyers would be proud of..........but when hovering my chopper for real my butt starts puckering if I go any further that a hover lol perhaps to do with the cost of rebuilds and the fact its really a cutoff saw floating in front of you and I am aware of the dammage that can be done,,,,I would think a buddy box would be the way to go when going to the next stage??
