Default What is a "rear lift truss"?

This rule seems to calls for consideration of the

relative wind is coming from behind.


The tailwheel folks might want to consider taking a lesson from the
glider folks and tie down with the tail elevated to get the wing closer to a
zero AOA. This greatly decreases the up force on the tiedowns when the wind
is from the front of the plane, as well as decreasing the downward force
when the wind is from the rear. Here in Florida, our summer afternoon
thunderstorm can easily create 50 MPH gusts, which can cause thousands of
pounds of force on your airframe and tiedowns. Why would you not want to
reduce that?

I have seen several varieties of custom stands used under the tail wheel,
as well as plastic milk crates, sand bags, and even spare tires.
