How about the Bixler which is the same airplane as the one mentioned above, the Bixler is sold by Hobby King, around $85 and it comes with the servos already installed, you will need at least two 2200 LIPOs, a speed control ( the sell a few for around $10 ) and your receiver or you can get a radio system for like $35.

I had one for 5 years and gave it to a friend he still has it.
Google this: Sky Surfer - aka Bixler mods.

One of the mods is to remove the 3 washers from the nose with hot water, now can use the 2200 LIPOs instead of tbe 1300, and CG is the same right over the spar.
