Ok guys working on my aerobatic sight now that I can fit the bird in the hanger with one installed. So, having never flown a contest or been judged from the the ground heres a question. Ive talked to a bunch of people and read a lot preparing. Being a non round wing airplane Ive heard the upline may be flown not exactly vertical with the airplanes level line or, the aircraft longeron flight level may not be vertical level and the plane should be judged by the chord line of the wing. Is this just theory? Will the airplane present vertical when the chord line is flown vertical? So, should I build my sight set to the chord line of the wing, and then make adjustments with ground critiquing? And...... for bonus points, what am I building the sight out of
