A few people told me that their Cobra trailers with aluminum tops
developed leaks. I wonder how frequent this problem is. Obviously
aluminum top is nice to keep it looking good, but one of the the
purposes of a trailer is too keep the glider inside dry. In New
England we sometimes get 4 inches of rain in a day. Thx, AK

I have an aluminum 2001 cobra, and have had several leaks. The major
problem is the seams around the tail doghouse. Artful application of
silicone sealer has stopped the leaks, but it took several tries. *I'd
be curious to hear of better fixes. Obviously, drilling out all the
pop rivets and then reassembling it with new sealer would be best, but
that is a huge pain we'd all rather avoid.

Next time, I'm getting the fiberglass top.

Well, even the fiberglass top can leak a little. When I put my plane
together the other day
there was a string of mud spots on the leading edge of my wings near
the root end. Those
parts of my wings are under the passive vents installed in the
trailer, so I'm getting some
moisture in through or around those vents.
