Detailed Description

Mylar Gap Seal

General Description

Pre–Curved Mylar is used for sealing the gap in-front of the control surface to increase performance of your sailplane. Mylar is attached to the upper and normally the lower surface of the wing bridging the gap and resting on the control surface. Pre–Curved Mylar is also normally found sealing the elevator and rudder. Pre–Curved verse straight Mylar is normally used because it will continue the seal as the control surface is deflected down. It is important that you replace your mylar when it no longer is curved and doesn't seal with the control surface as they move.
