Also, I believe in putting CA on the edges of CF parts to keep the layers from fraying under contact with other objects, but I didn't realize it actually added strength to the car. Can you explain that one as well?

^^ Im not to sure about the set screw idea but as far as sealing the edges go, the CF absorbs a fair amount of the CA, and stops the CF from fraying and being easily chipped like is what happens when a ball stud pulls out of the side of the hole, have a look if you ever break it there and see how the CF looks.
If it is only the holes that are breaking out, try using some really wide footprint #4 washers, preferably steel ones, use one each side of the CF deck on the ball stud, this will clamp the CF into it like a vise, and stop it from being as easily broken as there isnt a great deal of surface area around those holes.

Holy wow Popeye! Didn't mean to insult anyones intelligence, but take it however you want....I've yet to see a pic of exactly how these pieces are breaking. If the ball stud is being ripped out and making the holes unusable, the set screws would help. You don't think a solid piece of CF is stronger than the same piece w/ holes in it? Same concept. People have been doing it in on road for years. As for gluing, should be a given with any CF part. Ease up tough guy. Just a suggestion.

The ones I've seen broken had been using stock ball cups...

glitchy- Once again, I haven't seen a pic. But if the ball stud is ripping out, chances are it's happening between holes. The set screws MIGHT help to prevent this by providing support where there used to be nothing but open space. And it would be a cheap option. Can someone post a pic of their broken part please?

Most all of the parts I break seem to break where there's a screw. When arms break on my cars it's often through a hinge pin retaining screw (a screw that mostly fits the doesn't attach to anything or anywhere description). So, I'm just trying to understand why putting extra tension/pressure in an already fragile area is going to help under any circumstances.

glitchy- OK. How much material is there from one hole to the next? Couple mil? That makes for a pretty weak area. When the ball stud rips out, if this is indeed what's happening, it usually happens because of the lack of material between holes. If the holes were an inch apart(not a feasible option) the chances of this happening are greatly reduced. That being said, putting a set screw in an adjoining hole prevents the ball stud from ripping through that mil or so between holes.

My problem is that I think you've suggested something that may make the problem worse instead of better, hence the reason I want you to provide a sensible explanation as to how it will really help instead of further compounding the issue...and before everyone tries it and snaps a bunch more $20 parts just cause they heard on R/C Tech they should do it that way.

edit: Seeing as you added to your post, allow me to rephrase. I said it MIGHT work. I said it in BIG LETTERS so people would see the emphasis on "might" and not take it as some miracle solution. I know that I've done this in problematic, high-stress areas on other vehicles before and it has worked. NOW I'm done with you.
