are you talking about the little coroplast winglets used on a chevron foam wing?

If so i use goop and when they get really beat up i just run a Razor blade, cut them off and put a new set on.

Some people tape them on, ive seen people put thin ply at the tips and match the foil and glue them in and then screw the winglets on.

hope this helps

I just roughen the coro up with low grit sand paper, and Goop them on using a liberal
amount of Goop. Done that way, I've never had one come off in a crash. Usually they
end up getting torn up and I have to cut them off.

I use Goop too. A couple of 2mm carbon sticks CA'ed in the Coro really helps keep them straight.

That too. I use a sharpened pushrod to punch a hole perpendicular to the flutes across the
largest span and then slide a thin carbon rod of the appropriate size in there to keep the
winglets from bending over and creasing.

Slot x-weave tape through a small slot, like a "U" bolt to fastened onto the top and bottom of the wing surface.

Add a thin strip of tape from the LE to the outside of the winglet.
Back up with double sided tape or glue.

Used to do it that way, and was constantly tearing out the coro or just ripping them off the wing tips
both in combat and DS.

You can of course run a carbon rod up the fin in line with the wing root and use the tape as described but looping over the rod as well.

In my experience as well, I find it best not to mount too securely. Goop has worked up to 180 something...but I try not to combat...

I use 2 inch lag screws with goop. 2 per winglet. Drill some pilot holes and stuff goop in there with a screw driver. Gary uses 2 two inch staples using the same goop method. I've never seen him lose a winglet. We do a lot of combat though. Our wings are usually 20-25 oz. so the weight back there is worth the not having those things fall off.
