To answer your question, we will reinforce the joint holding the box in-place. But, beyond simply using epoxy alone, we will eventually reinforce this assembly by fiberglassing the joints.

On all these warbirds with a YS and high Nitro many if not all of us, reinforce every fire wall, whether it is an ARF or scratch built. On my Tsunami, I used tri stock, with 5 oz cloth and epoxy. I think because I run the bigger YS115 mine needs a bit more than , say a YS70 or 80, but those too need some reinforcing. Nothing worst than having it come loose on race day, when it is only a 10 minute fix in the shop to start with.
