I don't consider myself an expert in anything, but I do have some experience, and will share a couple of opinions. First off, $100 is a pretty tight budget to buy a Ready to Fly RC Plane with that would be considerd a descent flyer by most, but if you do some serious shopping around on some of the various auction sites, and also here in the RCU Market Place you might be able to come up with something. Actually a pretty good starter electric with descent quallity aircraft electronics and with a good flying abillity would be something from GWS like either the Pico Tiger Moth or even the Slow Stick. They don't handle much wind, but can be fun to fly in a gym or on a nice calm day!

Just a suggestion and something you might want to consider! $103.00 is also a pretty descent price for this package. I want to add that the radio is an additional $45, but good old used 4 channel radios are usually easy to find dirt cheap at about half that price!
