"Interesting, then this fiberglass epoxy matrix crankcase engine is best left without any type engine cowl enclosure, such as many 1/2-A profile and balsa log fuselage models and front mounted, where the prop provides additional cooling."

They were pretty well cowled in on the Fly'ems. The Zero especially. They also came with mufflers installed, which increased the head.

The issue on the BD-5 cooling was that is was a pusher, so no air flowed over the cylinder unless the ship was moving forward.

Again, it was glass-filled nylon, not an epoxy matrix. CF was still in the future and Testors would not have opted for that from an expense standpoint.
