I have a theory that Lancairs are like the Grumman, in that the purpose of
the nose gear is to keep the prop from hitting the ground when you run
out of elevator. On the Lancairs the problem is exacerbated by the
positive angle that the plane is set up with, to give more prop clearance,
and the relatively flat angle of attack, while holding a constant
altitude, until a low speed is obtained . I have experienced shimmy twice
when  I allowed the nose wheel to touch before the mains.  It is better to
drop it in from a reasonable height than to let the nose  gear touch first.
On one occasion I hit the nose gear hard and the shimmy was enough to
break the engine mount.
