Hey, what do you all think about G10 fiberglass as fins? Is it popular or not?
Thanks
I love it. I've used it exclusively for many years. Check the yellow pages for plastics suppliers in your area, they may have good deals in the cut-off bins. That's how I usually get mine.
On modrocs, if you can get the really thin stuff, you can just cut it with heavy duty scissors. Makes a terrific replacement for the standard balsa fins.
On rockets using H and I motors, I usually use about 1/16th thick G10. I use this on my G power camera rockets too, because they need extra stiffness. J power gets .93", or 1/8". 1/8" works fine for K power.
The dust should be avoided -- wear a dust mask when cutting. I use a sabersaw with a blade designed for metals and plastics. Usually I stack four pieces, tape them together and cut the fins all at once. Sometimes I cut them on a friend's bandsaw or tablesaw, if he has the right blade installed.
Recently I've tried the 1/8" honeycomb sheet material from Giant Leap. This is a lot easier to cut that G10, and the finished fin is lighter and stiffer than 1/16" G10. Very nice stuff!
