I tried to maiden my turbine glider yesterday. It's a 3.5M Reichard MDM Fox with a Wren 44 placed above and aft of the CG. It's a bit nose heavy, but I favor a forward CG until I sort it out. Upon accelerating for takeoff, the model would nose down and drag it's nose in the grass. Naturally, I could and did not takeoff. In my view, the turbine's incidence is wrong, (presently it's level with the airplane's centerline) but should I direct the thrust upward or downward to correct the nose down attitude?
