InstaMorph R/C Plane Repair

by stonekap | August 17, 2012 | (41) Posted in Projects

InstaMorph is a revolutionary new moldable plastic. As soon as I became aware of this stuff I had to have it! I bought the biggest container they sold...

I was very excited to find my first project. Fortunately I just crashed my Multiplex Twinstar II. This plane has definitely seen better days. However I was not ready to decommission her just yet.

The rear main wing attachment was a proprietary component made of plastic. There are a number of ways I could fix this. But this particular job seemed to be perfect for InstaMorph!

InstaMorph is activated by heat. The instructions call for putting InstaMorph into a cup of 140 degree water for 2 minutes.

I heated a Christmas Mickey Mouse mug of water in the microwave.

I made a video to show the molding process:

All done!!

I added a piece of masking tape overtop of the finished piece to protect it from the sun. I have flown the Twinstar II multiple times since this repair... seems to be working just fine.

Here is a link to the container I bought...

Looks like a great product! I could see a lot of uses, and not just repairs but also custom molded parts. :)

Really nice!!!
I broke exactly the same part and it's impossible to find a spare here!

Does it work without a Christmas glass as well? :)

Really nice article. I don't know how flexible that material is, but I would give to that wing attachment a pre camber so the two sides push the ''nails'' down as the screw goes in. *****

Very cool :)

Looks very similar to the stuff that they include with halloween fake vampire teeth and "grills" that you mold directly over your teeth.

I just wonder if this would be affected by sunlight in a car during the summer as much as hot glue. Fixable of course, but just something you need to keep in mind I guess.
Thanks for sharing!
