First real almost full flight with the Extreme. Propped it down to a 11X7 instead of that 13X4W prop just to relive some stress it generates and it still had great power. Actually even played a bit with it seeing how balance it was inverted and very little elevator required to stay level so maybe a little playing with the cg . Rolls no problem and and it seems to keep a straight line, loops are easy and heck I even did one knife edge. But there was a little snap and then a slight vibration so I brought it down quick before anything left me and it all came home in one piece. Slight little crack in the motor mount and I think I have the cure for that.
