the full length
I just just mine the same shape as the KR legs the fit the Kr mounting
brackets.
They seem very solid and still. Are you still happy with them or had
to modify???

The Grumman legs are the same material as the Diehl legs, 3M Scotchply,
as I recall. They are slightly thicker (1/8" or so) then the Diehl
legs. With that in mind I would guess that a Grumman leg up to 30" in
length, cut to the same profile as the Diehl leg, should perform quite
nicely. My Diehl legs are 30" in length with approximately 1/8" of
glass added to thickness and foam lead and trail edge for streamlining
and to enclose the brake line. If you go to
https://www.youtube.com/watch?v=cgdgxVgPNAk and watch the landing you
can see their limited amount of flex without being too stiff. I think
they are JUST RIGHT judging from the many landings / t.o.'s on grass,
some quite rough. They seem to handle rough surfaces without
transferring a lot of movement to the air frame and at the same time not
being too soft.
As always, YRMV........
