Starmax 63" P-51 "Gunfighter": The Exhaust Stacks.

I had some "piddle time" so I thought I would copy Kevin Greene's mod on the exhaust stacks. I used my Dremel with a coned shaped disc to cut out the holes in the stacks. I cut a hole thru to the engine compartment, and then took the Dremel with a rounded head cone attachment and cut a channel down to the last stack.

I painted the opening and channel with flat black to fill in the back drop. The inside of the stacks were painted MM Steel to give some contrast.

I found out, using a my own version wind tunnel which comprised of a cigarette and some compressed air, that when air pasted by the exhaust tips it actually sucked the air out of the motor compartment. With these exhausts at the top of the motor compartment, keeping the heat away from the lower vent ducting should work great!
