Want to see videos of the test setup, huh tfarmer?
Sure! Probably next year! LOL. I have a LOT of work to do before that.

Thanks for spelling out your cooling system, Saramos. I hope that it will
work great! Here's kinda what i have in mind for the Mustang:


The green area is a representation of the pressure zone beneath the aircraft,
Blue is the path air will travel through the plane, yellow is air exitting the plane.

Air will enter below the nose, as it does in the real aircraft (and now I think I
will try to make it enter around the spinner too. Thanks Saramos!). I will try
to fit a fan behind the engine (purple) which will force air out of the exhaust
stacks. If it cannot be fit, then hopefully some air will be forced out naturally.
Similarly, there will be holes drilled in the chin (like on the real aircraft) that I
hope will remove some air. The rest will be sucked into a duct (which has a fan)
that will send it to the rear radiator. The radiator door will move with the throttle.
The duct will probably differ from this figure. It will travel above the wing to avoid
the ribs & spars.

As an alternative, I might install a fan underneath the engine to pull air in through
the hole pattern in the chin and blow it upwards at the engine.

One question about cooling in general:
I've read on these forums that it doesn't really matter how SMALL your inlet area is,
as long as your exit area is at least twice (or three) times as big. I can't seem to
wrap my head around that one. What do you guys think?
