You can actually buy adapters for your servos to convert the old 3 pin (Futaba G) to the more modern setup (Futaba J, JR, Spektrum, Hitec, etc). http://www3.towerhobbies.com/cgi-bin...?&I=LXH449&P=0 However, at nearly $8, they're not a bargain, as you can buy new standard servos for $10. http://www3.towerhobbies.com/cgi-bin...?&I=LXUK84&P=7. So if you keep your current setup but upgrade, you'll need to drop $200 for a new radio, then hope the engine doesn't give you any problem. If it's worn out or abused, plan on spending another $60 for a new one of those. This bargain deal is adding up fast. If I were you, I'd give serious consideration to reselling the plane, then opting for a more user friendly RTF foam electric like the $180 Hobbyzone Cub LP http://www.horizonhobby.com/Products...ProdID=HBZ7300 or if you can swing it, the more feature rich Eflite Apprentice (comes with a full range, 4 channel 2.4 radio that you can bind to other models as you get more experience) http://www.horizonhobby.com/Products...ProdID=EFL2725 They come with everything you need, you don't need to mess with fuel, ignitors, starters, field boxes, etc. Very user friendly if you don't have any experience with R/C flying. Glow power for smaller models is dying, so you may want to consider starting off with e-power. I'll probably get flamed really bad for saying that, but it's the future of the hobby, like it or not.
