    John, take a look at the gear on John Hauck's Mk III. Yes it takes some major mods to do it, but it can be done. The other way you might consider is the Grove style bent aluminum gear. That would be much easier to install.

Notice how m uch the nose is crumpled and the plane is in a "lawn Dart" position. The bro ken boom tube is quite a ways past where the prop would strike, plus the pro p is still on the plane, so I doubt that the prop was involved in the accide nt at all, perhaps other than running at the time. The original picture show s the runway about 2-3 hundred yards behind the plane. >>> >>> However it is perhaps foolish to second guess anyone much less this poor guy. >>> >>> I once stalled about 50 feet above my runway trying to master slow fligh t. I looked away for a second and the plane dropped nose down, as I watched m y ASI go past 30 MPH the wrong direction. I was in a steep angle descent whe n I punched the throttle full forward. It of course took a looong time to sp ool up, but I managed to get it into a close to level attitude before impact but I still hit one gear leg hard enough to break off the axle of my right g ear leg, and bury the gear leg all the way up to the bottom of the cage.
