How To - Create a Kevlar Skid Shield
From ItsQv
The first time I used this method was in 2003 when I was building a Sig Models LT25 balsa model. In the instructions they show how after the wings are glued together you should put a layer of fiberglass across the seam and soak it with thin CA. I was amazed at how strong this made the wing join.
Looking through RC Groups to find a better way to create a rock shield or skid plate, I found a few posts on using CA and lightweight Kevlar cloth. This article then covers what I have learned about this including a cheap way to make awesome Kevlar cloth cutters.
