Is this a smart thing to do?
There are two very nice airplanes available if you want to stay with electrics. #1 Sig Rascal, ARF with motor and esc included. The other is a build it yourself Goldberg Mirage 550 which includes the motor but you still have to supply the esc. Both will get you up and flying so you can accumulate experience before you try the flying wing thing. Both will also require radios. Don't get anything less than a 4 channel FM and preferrably a 6 channel. If you just want to punch holes in the sky in the street in front of your house there is always the Slow Stick by GWS from Horizon Hobby. A little cheaper but still a good trainer. Be sure you find an instructor. It will be esier to learn to fly the actual bird and cheaper because you won't have to make so many repairs.
