Well, not to break up all ya'lls totally mind numbing discussion of cg placement and wing loading but I have a question. [&:] I have just finished my second scratch built plane and test flew it last weekend. upon take-off it went up and no amount of elevator could bring it back down. A guy at the field helped me get it down by several knife edges and stalls at idle. when I got it down he said I should shim the trailing edge of the wing up, or the nose of the engine down. Here's the question, which is better? wing angle of attack adjustment or engine angle of attack adjustment? BTW it's a OS 91 FX on a 60 size high wing model with a flat bottom wing
