T. Bob has the right idea. Completely enclose the cans off from the inside of the plane because you don't want the heat going inside the fuse. Plus you will get much better cooling by forcing all that air out the bottom of the fuse. I also intend to close off the fuse with 1/16" or thinner balsa from the engine area, again to keep the hot air out.

I intend to start assembly this weekend (HINT HINT ..... TOM ???) providing my plane comes in. It will be several weeks before I get it in the air because all my servos have to go to Horizon for a check up. I might even send in the 10X for a tune-up while I'm at it.
