There is an article in this month's issue of the Australian SAAA journal "Sport Aviation" about Graham Schott's KR2 VH-XXS. This aircraft recently lost its propeller in flight and Graham and his wife Sue made a safe landing on a highway.
It looks like the crankshaft had a fatigue failure near the prop hub. The article didn't give any engine details but according to the Australian register the engine is a C-85! There are some photos of XXS at http://home.hiwaay.net/~langford/gschott.html. Phil Maley Perth Australia
