RE: Epoxy mixture?
Glue DOC, I'm surprised you use regular epoxies. I have heard that industrial epoxies are much stronger. From what I understand industrial epoxies have weird mixing ratios such as 30:1, and that our hobby epoxies are use extenders to create the 1:1 ratios. The extenders supposedly weaken the epoxies to some degree.
Here is an epoxy I was going to try some of this, as I have heard it was very strong. Sure normal hobby epoxies work for most applications but for a 2 meter pattern plane that will see 3-400 flights in a season, I'd pay more for the piece of mind.

Also I know of some adding this as well for strength and weight savings.

Just wondering what your 2 cents are, Thanks Dylan
