I'd say don't buy an RTF with the forward thinking you're already doing. Best plane would probably be a Slow Stick, cheap, easy to build, and very fun to fly. Get on Ebay and buy a GWS 2002 field peak charger for $25, it will charge any nicad or nimh battery that any of the park flyers use. If you really think you'll be into this hobby go for the Hitec Flash 4 or 5 computer radios. About $170-$200 but you'll get servos and a receiver you can use with the SS. You can get the GWS pack with a 4 channel Dream Starter basic radio with servos and receiver for around $120.
