Another option if you have a 3D printer or know someone who does, you can print these parts I designed to replace the Skewers.
I had the same problems with the pins breaking the foam or the skewer pins breaking on hard landings or crashes. Once I finally got a 3D printer I designed a part that is easy to install and easy to replace if it gets broken. It protects the foam, and doesn't use the wood skewers. These just push on where the skewers would go, and attach with 2 3mm screws. The pins are 4mm, so if anyone want to use them, you might have to ream out the power pod holes just a tiny bit to get them to fit. I posted a pic below of them installed on my Bushwacker, and on my P-51.
Anyway, just another possibility.
