I'm a new Kit Fox owner and have sustained some major damage due to towing and neglecting to secure one wing properly. I will, in the future, and suggest anyone else do the same, provide a redundant way to secure the wings during towing. I haven't worked it out yet, but it will probably be a highly visible lanyard or ratchet strap.
My left wing swung out while towing at about 50 mph and struck a road sign. The wing swung past the fully deployed position, possibly another 45 degrees. The cabin top sustained major damage. I am currently having a new Hat-Rack being built at Kit Fox, which I will replace all the damaged tubing. The left wing sustained major damage, and has been repaired. I am currently applying finishing tapes to the cover.
Hopefully it'll be flying again this spring.
Cheers,
