I am building my STA-M and finally reached the point where I was going to mount the engine to the firewall tonight. When taking measurements to line things up, I noticed the firewall is not square with the fuselage. In fact, it is skewed by 1/8 of an inch. Consequently, I can't line up the engine along the centerline. Is this a problem others have experienced with this plane? If so, is there any remedy you guys can recommend? If need be, I will call Great Planes and/or Tower Hobbies to demand they send me a replacement fuselage, tail feathers, and new fairings. [:@]
