RE: please help make carbon landing gear

If done properly, it will not de-lam, and would break before bending. If it bends, it's probably to thin to begin with, or made with the wrong type of resin.

RE: Parting Wax nightmares...

Meguire's Gold Carnuba Wax is THE best! It's easy to use and does a great job. I've made literally thousands of parts with it. I always apply 6 coats to a plug before lay up, and six coats to a mold...

RE: Glider ID and questions

Glad I could help. I don't get out to fly as much as I'd like these days, so it always makes me feel good if I can help someone.

RE: Glider ID and questions

I can't say I recognize the specific aircraft, but I can tell you about holding the wings and stab on. Judging by what I see, it should be a fine flyer.

RE: Mold Flange Adhesive

Jake,

I used to use clay and a razor blade myself. Try the bondo method on your next mold. The first time I tried it I was amazed at how much better the joint between the two halves was.

RE: Mold Flange Adhesive

Moldmaker is right. The best flange edges I've ever gotten was using bondo. Leave a little sticking up above the flange, pop the plug out, sand it flush with the flange, re-install the plug and lay...

RE: Want to built airfoil tail insted of flat

A good choice for tailplanes is the NACA 008 or 009. The numbers indicate camber and thickness. The camber is zero (symetrical) and the thickness is either 8% or 9%. Another good choice is the Helmut...

RE: New to Scale Gliders

Although I haven't flown either one of these aircraft, I can make an evaluation based on their specs. It is made easier since they both utilize the same airfoil. The ASW22 with the 2.8 meter wing...

RE: Hinge Tape

If you check with the specialty sailplane suppliers you will find several options. Also, I have used 3M 600 clear tape on sailplanes that flew over 100mph with no problems. Only drawback to 3M 600 is...

RE: Wing Sheeting Question

any of the products you mentioned would work fine. Without vacuum bagging, balsa might be the best bet. Obechi is another good skin material. 6.3 inches is a pretty short chord for an 8 foot wing. If...

RE: what kind of FG mold separator

Two things;

1. To Cadmn; We use Epoxy because it is more stable, stronger, and less brittle. It also is much nicer to use since it doesn't smell so bad.
