I just read Matt's comment about breaking a rudder attachment during trailering his airplane.
A friend ofmine trailered a Cassut from the San Francisco Bay Area to Reno and on arriving he found a broken engine mount.
They welded the mount and raced.
He mounted a G-meter on the engine for the return trip and found the meter pegged at 10 G's.
Be careful Trailering an airplane.

[In the glass industry the rule is "If it can move it will break", so
we take great pains to insure that all shipments are completely and
solidly immobilized.  I trailered my kit from S'n'F and followed that rule and didn't experience any problems whatsoever.  With a kit that's already on-gear, however, and assuming you're going to tie it down to the trailer with it standing on the wheels, my recommendation would
be to use binders (no ropes here) to compress the donuts and nose gear
strut to the point of eliminating any up/down motion of the airframe.  Don't
attach a tie-down to a single point on the airframe (like a rudder hinge bracket), but rather loop the binder strap around a major portion of the structure and tension from both sides... pulling down an inverted V
formed by the strapping restricts motion in two directions, and when
additional strapping is added it should always pull against the direction
of previously installed bindings.  If you can move the airframe without
imparting the same motion to the trailer the tie-down job is inadequate.  So if you're going to move your project, get some straps and binders, don't
tie anything to small components, and keep the whole assembly immobile.
You should then be able to trailer it safely and without damage.  I hope this helps.
