You really can't tell it but the "plastic" is really pretty rigid and is definitely some type of FRP. Remember, the Robart gear for the TF GS Mustang have a plastic body as well where the cam moves. They held up well for me on several "imperfect" landings. I sold the Mustang to a fella up in Ohio and he loves it, retracts and all! JMTC!
Happy Flying!
