First, find a local club and an instrucotr to get you up. It will likely allow you to keep all those planes in one piece, for awhile at least.

Here's a link to the AMA's website. They have a club locater page where you can plug in your Zip code and get a list of local clubs. http://www.modelaircraft.org/templat...677786D06500E8

I'd advize that you start with the Megatech trainer. It's possibly the worst of the planes you bought (do a search for Megatech here), so it won't hurt so much IF it crashes. Save the Kyosho Corsair and the Giles until you've flown at least a couple of other planes, AND learned to fly them well.

Good luck, have fun, and welcome to RCU!
