First you need to decide on what size airframe u would like to use. If you go with something like the kaos 40 or magpie 50 then your battery (lipo) would be less, charger needs less, and motor/esc. Or, go 60 or 90 size.... heck even full 2 meter but that is very expensive.

After re-reading your post, I would recommend the kaos 40 from tower hobbies or you might look into GCBM Models from pasadena area http://www.gcbmrc.com/arf_index.htm the harmony sport 40. E-flite just came out with some good otrunners or you could go hacker with a gearbox. Lots of options in motor selection and i would use an astro 109 charger to begin with.

Good Luck.
