Been a while since I posted here.
I have been playing around with using carboline down LE `s rather than a fabric weave. So far I`m impressed with what I`m able to do by using carboline LE`s

Hi I just ran across this thread, I mess around with fiberglass a good bit and a little bit with carbon fiber but not really enough to understand this. Whats carboline? Also whats that yellow stuff you've covered the horizontal stab with in the last few pictures?

Carboline is a carbon fabric like no other. It is not really a fabric but more of a uni directional carbon tow alternative. http://www.hyperflight.co.uk/product...abric-30-39g-m

The yellow material is simply kevlar with a very slight bit of yellow pigment added to the epoxy

Wow that stuff is light! and not terribly expensive too! so why the pigment? and why cover it in kevlar instead of carbon?

The cost of the carbon is good partly because there is little waste. If you noticed the direction of the fibers it is unlike any other fabric. No wasting of large pcs of material so you can place the fabric on a bias.

The pigment just adds a nicer tone of yellow to the kevlar. The kevlar over the blue foam ends up looking like beige.

Why use kevlar over carbon? I build tail parts to sell so I build parts with various prices for various conditions

Quick newbie question: Why make the stab out of 2 pieces, instead of just one? Wouldn't a one piece weigh less (albeit a very small number) and without a joint that could possibly fail?
You really have quite the impressive cottage industry going there! I'm totally envious, I wish I could keep my shop area as organized!

Just received wings and tail feathers from DLGjunkyard. I cannot believe the quality of the work. Very impressive. Now it's time to install top drive. Again, a huge thanks for the help and build tips.
