Repair the Mylar covering of Carbon Butterfly

Mylar has come loose from the Carbon Butterfly Airframe. How to Repair it.

You might notice that the mylar has come loose in flight - it has ballooned up in flight where it has broken free from the carbon rods.

To fix this, we want to re-attach the mylar to the carbon rod. This can be done fairly easily if the mylar film is intact.

You can use contact cement, 3M77 contact cement sprayed into a small recepticle, flexament, or even medium CA glue.

Apply the glue to the carbon rod in the area where the mylar has come loose. The glue should be applied with a Microbrush dipper, or equivalent dipper stick (like a toothpick) - microbrush dippers are the best for painting on the adhesive glue material to the airframe.

Next you just have to pull the mylar material carefully and set it on top of the sticky carbon rod. Once it's there, just make sure it's making good contact - you might have to press it down a bit with a bare plastic rod - don't use your fingers or you could get a hand full of mylar. Let it dry and you are back in business.

Hole in the Mylar.

Holes can be patched in a number of ways.

You can cut a small piece of mylar slightly larger than the hole and then use it as a patch.

You can even use a small piece of clear cellophane tape - don't use too much - it's heavy.

Or you might have to dissassemble the airframe part with the hole, remove all the mylar covering and re-cover the airframe part again with mylar.
