Hello all...just picked up an Aerobird Challenger. The LHS pros said I shouldn't have any problems with it at all. They do a pretty neat thing here. Whenever a customer comes in all googley-eyed about a nice shiny new red bi-plane or a speedy warbird they sit them in front of a simulator and after two or three crashes, recommend a trainer. It's hilarious...humbling too. I tried a 3ch similar to the cub and wrecked a few times....go figure!! So I'll be posting anupdate with news from my maiden flights...thanks a million.-Paul
