Yes, Take the word of a man responsible for the demise of a couple warp

--->  Hi, Jim!  I recall Paul McAllister making a comment regarding this
when I was flying with him in his Mono some time ago.  He said you told him
it was impossible to wheel land a monowheel.  Some of these landing issues
might be related to the position of the main gear in relation to the CG.  To
wit:  Cessna 140s had two gear versions, straight and swept forward, with
the axle centerline 3" farther forward.  My flight instructor made the
comment that my 140, which has the straight gear, was much easier to wheel
land than the 140 that the FBO owns, which has the swept gear.  Indeed, the
extra weight behind the CG with the swept gear would make the tail tend to
rotate downward with any vertical velocity component when the aircraft
touches down on the main(s).  As the tail drops, presto, you're flying
again.  I've pulled a few of those with my 140, and usually after the nice
*sproing* from the spring gear and finding yourself 10' high with no speed,
firewall it and go-around for another try. 

I'll have to look at some drawings of the mono to see where the main gear
axle CL is compared to the LE of the wing.  That might be a clue.

Nevertheless, I find this most interesting discussion, and good prevention
of having our prop eat the ground someday.
