Raymond, - The plans call for 1/8" plexiglas. Many builders now are using 3/16". P lexi and lexan each have good and bad points. I am building with 3/16" tint ed and coated polycarbonate(lexan). The coating improves the fuel/chemical resistance. Plexiglas is cheaper and will also do the job.

Greetings, The airplane I'm designing will probably have a windshield shape similar to the Tailwind.- Can someone tell me what the dimensions of the material us ed for the windshield, including thickness.- I see some people are using lex an, which will be my choice.- Anyone using other materials and can offer pros and cons of the various choices?- My gas fill will not be near the windshield so exposure to gas is not a big issue. Thanks very much in advance.

Funny how Plex has worked for many many airplanes for many many years........... It's still a viable way to go. However, Eric's using perhaps the "best" size and material for the application. It also costs more....... Weav Mike & "Jaz" wrote: > > In a bird strike....

The center brace is absolutely needed to strengthen the 47 inch long windsc reen. The Cougar has about half that length and-uses no center brace. The width is about 39 inches. I don't have the plans in front of me. Some buil ders also add clear plastic blocks or other supports above the diagonal fra me tubes-directly behind the windscreen in order to add bracing strength. -Paul Baron lost his 1/8" windscreen in a high speed dive. He survived, b ut increased the thickness from 1/8" to at least 3/16" when he made the rep lacement. He also had to change his underwear. --- On Fri, 4/3/09, raymondj wrote: From: raymondj Subject: Re: Tailwind-List: Windshield question. Eric, Thanks for the reply.

Eric, Thanks for the info. I will be putting in 3/16 lexan with braces unless they find something tougher before I get around to it.
