I have this plane and the instructions say 42mm aft of where the leading edge meets the fuselage. This equates to about 1/10th of the chord instead of the usual 1/3 chord. It cant possibly be right because every other plane I have flown over the last 30 years is 1/3 chord.
It looks like it should balance on or near the wing tube which would be 123mm aft of the leading edge. 42mm just doesnt make sense.
Can anyone shed light on this please.
