Rob,

Instead of using the U shaped piece of fiberglass that comes with the F-16 I made a heat shield out of .016" aluminum to go over the area between the rear of the engine case to the pipe bellmouth. Also I put aluminum tape on the bypass underneath the engine in that same area. The outer pipe stays relatively cool compared to the inner pipe and as you get further away from the engine the cooler it gets. Nonetheless I also stuck some aluminum tape to the inside of the fuse above the pipe (heat rises), from the engine hatch to about half the length of the pipe. The formers and inside of the tailcone were painted with BVM Heatshield.

How much does the FS70 weigh? If you read back in this thread you will see that myself and a few others had to add considerable nose weight to balance the F-16 with the engine in the conventional location. Anything heavier than a P-60 or Super Bee (about 800 gm.) in the tail would cause the plane to come out heavier after balancing than if it was mounted in the conventional location.

I have a Wren SS, mounted conventionally and shifted as far forward as possible, in mine and had to put 24 oz. (700 gm.) of batteries in the nose to balance it. If there were any more weight up there I'd be worried about breaking off the nose first time I bounced a landing.
