     I need a little clarification here.  First, how much lift can the
wings produce at 10 knots?  Not enough, I suspect, to keep the plane
from tipping over while perched on one landing gear--unless there was
quite a headwind.  Second, I don't have a model in front of me, but I
suspect that when the plane finally did tip over it came to rest on
the one landing gear, an engine nacelle, and part of the nose.  While I
can believe that there might have been only some skin panel damage on
the nose, there must have been some damage to the engine...maybe it
was possible simply to replace the nacelle and engine within five days.
