I have purchased some equipment and planes from a fellow and one of the items was a GP Spacewalker 79" NIB. Also there was an extra used wing for the plane. The used wing is 79", as per the specs on the box for this plane. But the wing (new in box) after assembling, was 82". The ailerons are 1 1/2" longer as well. Both wings fit perfectly onto the fuselage. Just wondering if the 82" wing is an upgrade from the original spec advertised. Anyone know what's up?
