Well, it has been some time since I posted, here is what has happened with my Chipmunk. As you know she landed twice passed the runway because the engine quitting on me at the wrong spot also I did rebuild the landing gear mounting rails.

I had yet another landing away from the runway, she landed flat and without damage again, the main gear wires got bend during that crash landing but the rails stayed right in the wing so, my rebuild in the area worked just fine.

The engine is now working flawlessly and it doesn't miss a bit, I went to fly today and got 6 flights, all I can say is this is one super airplane and with the OS 91 mounted on the nose you can't ask for more the combination is just awesome!!
