I went to see the Stormbirds hangar at Everett, Washington, and the first bird was only slightly damaged. There are no Me-262 langing gears available, so they cut down the main gear from a Grumman S2F and used that. The uplock worked, but not under side load.
The landing gear is a critical item since it cycles so slowly ... as the original units did. They aren't trying to make "Super Me-262s," but rather 100% replicas, so the landing gear cycle speed is identical to the original.
These people are professionals and are both talented and dedicated. Their 2-seater is no joke; it flies and has been delivered to the owner. Messerschmitt thought enough of their effors to award them six new sequential RLM numbers for their airframes, and bought one from them to the Germans.
You should check it out before criticizing ... I mean go to Seattle and look it over. It's worth the trip and these aircraft are built to the drawings, not to any "new" standards.
Their airspeed is limited to 500 mph. The newer engines will drive it much faster but, if you go there, you are a test pilot flying an airfoil that was designed when planes that got too fast dived into the ground without possible recovery.
A really neat endeavor.
