Hi Pavel -

I have owned both. I had an Avionic trailer for my PW-5 and have a Cobra trailer with my LAK17at. Both had fiberglass tops. Both were well outfitted with jigs, etc. Both were about 2002 vintage.

I really liked the fluted floor of the Avionic trailer. The Avionic trailer had more running lights around the exterior and on the tire fender.

The Avionic was higher than the Cobra. They both trailered quite well. I'd have to give a slight edge to the lower Cobra in high cross winds. I can tow at a little faster speed than the Avionic before I'm concerned about sway.

I hope this helps.

Lou
