Bug e-fun

I have an orange glider, Bug e-fun or something, around 600mm wingspan.
I have receiver, servos (rec from the flea, 1x metal servo from butterfly and 2x 5g servo which was aborted from Orange), new motors (1806 or something) and 6A esc (turnigy), both from Hobbyking.
Let's modify it so I can test how much thrust I can get from the 1806 motor/esc and GWS 5" prop combo.

Bug-e fun has low dihedral.
It didn't flip over and remain right side up when I last flew it.
It ought to be enough, but maybe it isn't.
Maybe the introduction of a 5" prop will make things too interesting.

I must have rudder, so let's settle for full-house and have ailerons and rudder control.
