Just a heads up about a serious problem I had when trailering my SS7 tail-first.

Due to an emergency landing at a rural airport, I borrowed a trailer to get my Kitfox back home, about a 130 mile trip. The trailer was built for a Kitfox and worked very well; it was a tail-first design. I immobilized the rudder so it wouldn't flap in the breeze, and tied the control stick fully forward to immobilize the elevator also. I drove the 130 miles home at about 50-55 mph because I could see in my rearview mirror that the wind was pushing very hard on the elevator. Got it home and everything seemed fine. After flying for 25 hours I was doing a casual inspection and noticed the rear elevator control pushrod had quite a wow in it. I took it out and inspected it and found a pronounced wow but no kinks or cracks, so I straightened it and reinstalled it and everything is fine now.

The cause of the wow was obviously the trailering. The elevator was in a down (nose-down) position, so the wind force from highway speed caused a compression (buckling) load on the pushrod. It was a strong enough force to permanently bend that pushrod, which really surprised me. I can't imagine the damage that would have been done if I had traveled at 65-70 mph. My takeaway from this is to never trailer tail-first without immobilizing the elevator by some means that doesn't put a compressive load on the control pushrod. Probably many of you already know this, but FYI.
