I'm going a different way here,,after all it is a very diverse hobby...I started at a local school yard with a GWS pico stick...if the park flyer was "sweet" than a .40 glow trainer maybe be bigger than you want ...I fly 1/2A (.049) planes at my club field,,most dont recommend them for training ...I dont go with the simulator crowd either..you can find FMS and do a free download of a sim and use your keyboard buttons to fly it...you should have asked the guy that was flying what it was ,,he may have been glad to let you try his or helped you with your questions anyway...it can be costly to start,,check with your local club they probably have a club trainer so you wont need to show up with one.....clubs are like any other groups,,you may run up on a group of snobs (it happens) or meet some new best friends (it happens too) maybe run up on a "knowitall" that can't fly (look for repairs)....some people like to teach and others dont, so ask at the field if they have someone designated as the trainer,,but not while their flying..I have seen people carry on conversations while flying and others absolutely cannot answer yes or no questions, it just depends on the person..read more threads,,read,,read,,read....check the parkflyer forums too.....Rog
