Hi modelers, I have a dynaflite 1/4 scale super decathlon that i am trying to balance ( finding CG ), i have a brison 2.4 bolted on for power. A very light engine, what i did in order to find CG is i measure 3 3/8" from leading edge of wings according to manual and mark it, Then place a string between where each wing halves meet at the area marked, then suspend plane from the ceiling of shop and add weight to nose until the plane straightened out but then all that weight added to nose in order for tail to line up make the plane very heavy, I weighed it with one of those cheap spring scale from harbour freight and it is showing a weight of 22lbs, I know this is serious problem, any helpful advice from anyone will be nice, thanks,
