Distortion

In maneuver drawing in F3A field, apparent improvements are observed after correcting any torsional strain in the wing construction and assembly distortion of the parts promptly. Though a model airplane I'm flying had been constructed by some old friend and been brought to me for free of charge, Yoshioka Pegasus ST gives me much opportunity to study how to adjust and correct bad habitual reaction caused by the upper reasons and supplies me much know-hows that are indispensable to go into F3A field in future. For example, the connecting portion of the main wing R/L had much effects to eliminate a bad habit to go rolling motion when knife-edge maneuver. Very slight mal-connection causes bad habit at main wing connection in the center. So, much care must be taken when central connective construction method with a carbon pipe was invited in relatively bigger airplanes. I just remembered the Akiba's saying,"Main wing should be one-piece construction and it should be fixed tightly on the fuselage at 4 points. This is a very important theory to obtain a better F3A competition model. The more accurate fixation in the air plane is the better.
