Composite V-Tail Lay up Pictures
Took some pictures of a V-tail layup that I did over the weekend.
Outer fiberglass .75 oz, 1/32" contest balsa skins, Inner fiberglass .75 oz.
Skinned hinge is .005 fiberglass laminate, with an additional layer of .75 oz slighter larger than the laminate.
I stained the wood skins for a little color, it would have looked better had I stained the fiberglass laminate also. I used Dave Brown Micro balloons mixed with the laminating resin / coladial silica to try and match the brownish / red color of the stain.
Molds were waxed with Dolphin Wax, PVA applied, and then sprayed with KlassKote Clear. Epoxy was EZ Lam 60 Laminating Resin, and the halves were bagged at 21" of mercury.
Not going to do a step by step, but just show the pictures that I took during the process. If you have any questions, please let me know.
Final weight was 2.5oz, slightly heavier than where they normally come out, but not bad.

I've used Kevlar, pretty stiff for what I need. These planes only need 1/8" throw on low rates and 3/16" on high.
To get more throw you would need to sand/file out the epoxy over the hinge line and get down to the Kevlar.
On ailerons I use .010 fiberglass sheet, but .005 works fine on the small elevator surfaces.

Great Post Dave, a picture is worth a thousand words, very timely for me since I am in the process of building plugs (fuse and tail).

Beautiful work![sm=thumbup.gif]
I really like the angled cut on the bottom of the elevator, no wiper needed.
Was this two or four bagging sessions?
You slipped CF at the torque rod exits, how did that happen?
You used clear Klasskote onto the mold was that cured or not before you laid on the first 3/4oz. glass?
