I just tried my SC on C.O.G. Machine and with the balance arms under the wing [because it is a high wing, on a low wing you test upside down and with wheel retracted if they do]
Any way the SC balances in standard mode with no alterations any where from 1.5 to 2.5 inches back from the leading edge.
I am supprised at that as other planes I have tested have a exact spot , not anywhere between 2 points as with my SC
If a fit a 3 cell lipo [dulsaky 1320] which just fits in the battery box, the C.O.G. stays the same, the battery is lighter but is in the same position as the stock battery.
