My Extra was maidened yesterday. Estimated weight is ab. 6.5kg. ZDZ40 motor with 22x8 wooden prop.
Flies very stable like on rails. Stall test surprised me: Extra just drops the nose. Landings are long because of speed. Too sensitive on elevator (factory settings are bit too high). Overall - very nice model

Georgee, you asked about maiden flight of my glider: it flies smooth and gentle - just like glider should fly
