I have installed the Grumman legs on my KR2-S. I kept them the original length and thickness but trimmed them down in width. Minor deflection as the plane sets now. Fuselage, tail, controls and motor mount (weighs 198 lbs). I have also used the fiberglass leg for the front gear. With me in the aircraft (250) gross so far at 448 lbs the gear deflect about 5/8". I expect a total of 1" deflection as engine, wings, fit out and fuel are added and dispersed across the 3 legs. -------------- next part --------------
I can send more detail and measurements if your interested.
