This thread started as a request for the dimensions for the Diehl legs. The Rand Robinson Engineering legs being replaced are 7075 aluminum, very similar to the one Steve just described and the mount/bracket is cast aluminum (very stout cast aluminum). The legs angle out at 22 deg. (not much angle) and the asssembly is very stiff. The test pilot commented on the stiffnes during taxi testying and after the first flight. I like the Diehl design and since they are not available and I have the Grummen legs, I thought I could mix and match to come up with something that will work. I am a "that's close enough" Engineer but when I can, I like to do some analysis as a guessing gage. I am comfortable with the assumption that the Diehl and grummen legs are very similar material. What I don't know, and accept that I will probably cannot know, is the orientation and stack pattern of each. If there is a 25% difference in the thickness , that is substancial and needs to be considered. BUT I have no idea because I don't know the dimensions of the Diehl gear. Does anyone have a set they can measure? I will really appreciate knowing shape and size of the Diehl leg.
