Kevlar is really tough stuff so you don't need a heavy fabric. I have used 1.7oz and 2.5oz cloth and found that the 2.5oz is not really any tougher and adds a lot of weight. You can find small pieces of 1.7oz cloth on ebay.<br><br>

Introduction

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.

Light Cloth & Cheap Scissors

Kevlar is really tough stuff so you don't need a heavy fabric. I have used 1.7oz and 2.5oz cloth and found that the 2.5oz is not really any tougher and adds a lot of weight. You can find small pieces of 1.7oz cloth on ebay where I paid $24 for a 1 square meter piece (including shipping).

To cut the cloth you can buy special scissors or for about $2, make your own. $2 is what I paid at a "dollar" store for a pair of Fiskar scissor clones. After you get your cheap scissors, clamp them in a vice and file or grind them with a course file or grinder against the sharp edge.
