Does it come unattached from the plane also or must you fly around with it.

 

Another point to consider (two points actually) is how it meets the skin.

On my plane, some damage was done because the mount point wasn't flexible enough as the tail was raised and lowered.

What is needed is a pin into a hole in the plane so it doesn't slide around - mounted in a ball joint and then well padded.

SD,

 

I tried to taxi with it attached - works in the snow and ice.  If you use aircraft power the mains can be raised off the ground thus reducing wear.

 

I don't know about anyone else but I use short 1/4" bolts thru an area washer threaded into tapped holes in the fuselage jack points.  The bolt heads fit thru the large area washer welded to the lift top so it can't slip.  Any movement is betwixt washer and washer.  I have never had any damage from years of lifting with this type of arrangement.

 

As is usual, your method is backward and upside down from the one I use.
