I can't believe that I'm going to say this, (at least not in a Dadratted ARF Forum), but, I've even stick built (yeah, it was years ago) some models that ended up with an out-of-square situation. (I really hate to admit this next statement ) Mainer Jim is correct. As long as the wing and stab and fin are in correct relationship to each other, (both in square and with the incidence in plane) the fuselage is kinda=sorta just along for the ride. That Cessna will in all probability fly pretty well. Do you have any idea of what the finished weight will be? I would be a little cautious of that, but there again, I have even less experience with those $$##@@ electric planes than I do with the $$##@@** ARF types.
