<br><font size=2 face="sans-serif">The question is do you want a pretty repair or one that will last?</font>
<br>
<br><font size=2 face="sans-serif">Most of the gear I have seen, and I have not seen a ZN Line gear, is unidirectional "airfoil" halves glued together. This is a very poor composite design, but is easy and cheap to make. Over flexing of the gear (poor landings) exceeds the shear strength of the resin matrix, which is thousands of times weaker than the fiber.The pretty repair involves re-glueing. If you are going to do this epoxy will work much better than CA, but of course takes more time and effort.</font>
<br><font size=2 face="sans-serif">The permenant repair (mo'ugly) involves taking a fiberglass yarn (unravel some fabric) and wrap it under tension (after re glueing the split) 90 degrees to the uni carbon. The more tension without breaking the yarn the better. You can use CA for this application as it will never get overstressed and it will help you be able to wrap with tension as you drip thin CA on the fiber. <br>

After a few less than perfect landings one of my gear legs is starting to <br>
delaminate. The gear appear to have a foam core. Can I just glue the halves <br>
together with foam safe CA? What is the best method of repair? Is this a <br>
common issue? Anyone have a spare set they are willing to part with?<br>
<br>
TIA<br>
