I had to add popcycle sticks under the trailing edge of the main wing. the incidence of the rear horizontal stab is not correct when the fuse was made at the factory. No it flys really great. My only issue is battery access. will have to make some sort of hatch under the battery to change it out, at present i am taking the wing off. That is getting old real quick. Not much of an aerobattic airplane just your basics. MY has unlimited climb due to the electric motor and battery i chose.
