RE: Balancing low-wing plane
Just a little something for 2 cents ... I only balance my planes for the maiden flight also its usually set slightly nose heavy, after that all balancing is done by flight trimming. I will get the plane into inverted flight and KE to see where the best compromose is. What I will do is to then move the RX batt pack about or to add some weight if necessary. This is still the best way to set your CG, again each of us like the plane in a certain manner. I remember when I first flew my F90, I had something like 8 oz on the nose, once I got used to the plane all that weight was removed. I guess the best way of setting a CG is still to fly her and not just taking measurements.
