Four Star 40 CG Needed!!
Somehow i have managed to leave my instruction manual laying around carelessly for the last time. Thank god my model is built Ive been waiting to put the motor and hardware from my trainer in it for awhile. Now i cant find the manual. Does anyone know the CG for the Sig 4*40. Ive searched and can only find specifically 2 3/4 from the leading edge and balanced inverted for the 4*60. Am i safe to assume this is the same for my 40 size with a OS 46AX. I Have also stumbled a few posts regarding the CG on the 4* Series being to far forward..Is this a concern or not. I guess you get the point. I need to balance the plane. Any help would be greatly appreciated. Thanks

Balance on the spar is correct. Couldn't find it in the Manual but it is on the plans. Better go for the forward part of the spar to be safe. Good luck
