So if I input all the dimensions into the calculator for my Phoenix Models Sbach 342 .120 size, I get a CG of 6.62" to 5.29" from the leading edge of the wing, yet the manual states the CG to be 4.53" (115mm). Then in some threads related to this plane, some people state that the plane feels tail heavy with the instructions CG of 115mm.

What to do. Follow the instructions or go with the calculator?????
