hi gordon.....
as long as it is moving forward through the gas (air)...and there are no
circulating currents in the structure....then it should climb slightly with
no control inputs....control inputs should react the same as far as pitch,
roll and yaw are concerned......however...the glider will rotate around the
center of mass.....not necessarily the CG....and as soon as the glider lost
forward momentum....it would just hang there.
thanks for the thought provoking queation...beats motorcycles..
