Builder Tip #77 from HomebuiltHELP 
Plexiglass or Lexan for Windshield & Doors ?
Choosing the right material for your aircraft glass means understanding the differences in properties of acrylic and polycarbonate
Sometimes the differences between lexan and plexiglass don't seem all that clear to us when confronted with the choice for building doors, windshields and inspection plates for our aircraft. The key is to understand the properties of acrylic plastics and polycarbonate plastics.

The differences in strength and resistance to chemicals (gasoline!) that may contact the surface are quite amazing.  These qualities and others mean that these two plastics should not be interchanged without careful consideration. Both are frequently used on the same aircraft as the application warrants.

Watch this short video to review the key differences between these materials and feel confident when choosing the right product for the job.

HomebuiltHELP gets one heck of an endorsement from this guy!

We were happily stunned by the surprise endorsement of ex AOPA president Phil Boyer for our video construction series on the RV-12 aircraft.

This short video was produced by Phil, unbeknownst to us at the time, for the purpose of sharing his experience in building his aircraft with the help of our videos.  Take a watch and see what a kind person he is!
