I don't think the cut at the top of my 30" gear legs is any different than what you see with the 24" Diehl legs. Mine have the angled cut against the spar and the flat side away from the spar. Oddly enough, mine was configured with a nose gear when I bought it as a project. That's not to say it was configured correctly, to include 30" gear legs and a standard nose gear which would make for a very strange sitting aircraft unless the nose gear was lengthened to match. I didn't buy the nose gear with it, and promptly took the mains off, flipped sides and mounted the gear to the front of the spar to make it a tail-dragger. I couldn't be happier with the balance of mine on the gear. I can lift the tail easily under power, but have enough tail weight and tail downforce that I can brake reasonably heavy without worrying about dumping the plane onto it's nose.
I suspect Dan came up with a different cut for the nose-wheel aircraft as many of the early tri-gears had a tendency to dump onto their tails during ingress. With the advent of the -2S with the longer/heavier tail, I expect that spawned a change in the landing gear. -Jeff Scott -------------------------------------------------------------------- > > > > > > > Mark J, I agree with you, as long as you can match the angle that will > > place your axles far enough forward of the main spar forward face and your > > airplane won’t fall on its nose! > > > > The only reason I felt compelled to post these instructions I received from > > Dan in 1988 was to try and make sure everyone understands what they should > > be doing.
