Get your nearly ⅓ scale (4.7m), almost ready to fly, ASW20 remote control glider he http://youtu.be/rfpRPIxkDDA

Notice the electric launch (FESL*), electric gear, spoilers, etc. Laughable is the dolly rig required to launch with the electric motor* due to this models huge size and weight.

If I had $1500 to spend, this would be good fun.
