I discovered that my ryobi has a gean in it that makes it dive for the ground (without much notice) and proceed to revert back to its original use. I scolded it sevearly and imediately removed (I hope) the gean so there wont be anymore urges to head for clumps of tall grass around the edges of the runway.

Actually, I did a low high speed pass over the far edge of the runway. We have tall johnson grass at around 5' tall. I new I would hit some but I didnt think it would yank it out of the air like it did. Hit the ground at about 80 mph but at a very shallow angle, got lucky. All the nylon bolt break points did their job and the plane suffered minimal damage. Allready repaired and flying again. I think that gean was in the spark plug. The ryobi took it pretty well. Just busted the sparkplug and mangled the clip in the wire boot. All fixed and running as good as it ever was.
