OK, these are a bit optimistic, because I assumed the engine added no
drag. It does show one engine is close to being good, but a 55-60 lbf
engine would be "ideal".

Have you math whizzes figured out how far the wing runner will have to run
before this dog whistle is going fast enough to have aileron control?

Wing runner? On an 11 meter motorglider? We don't need no stinking wing
runners! This is _Self_ launching! Put wing tip wheels on it and let it
roll! Actually, letting it slide on it's plastic pads would work fine,
since there is so little weight on the tip. The wing will come up when
it's ready. In crosswinds, put the downwind wing down, to help keep it
straight. The ultimate answer is a tailwheel with just enough steering
ability to keep it straight, since it doesn't need to taxi.
