Hi Jean-Philippe,
sorry, a little mistake. CG was by 45mm from the middle of the wing tube, not 40mm. Maiden flight was with CG 50mm, but i think this was a little too nose heavy.
Flap position are like the manual, works great. Start with pos 1. Landing with pos.2, you think someone will hold your plane when you get full flaps
regards
Jörg
