I am have seen the compact dimension of thr RCV engines
which can be fully enclosed inside the cowl.

My question is: can it be fully enclosed ifor a true scale
appearance in an aircraft like the Spitfire or Hurricane,
with no openings other than for the glow plug?

These two aircraft do not have any front end openings
for air-intakes, radiator opening, oil cooler.

Will the engine overheat fast? Or is there a way to channel the
air from somewhere else into the engine bay?
