Lots of ways to skin a cat huh Ace.
I went the old school down and dirty. Not the prettiest of setups but it works well.
Working on more details. The Jantrol heaters had their stacks on top. My tech advisor sent me pics and mentioned this:
"John, I wondered why I was seeing 9 exhaust "stacks" (5 forward short ones and 4 taller ones behind those) on the Fuselage ??? Of the 5 lower, forward exhaust stacks, I think the center one is the APP exhaust and of course the other four are for the heaters."
I used the old plunge method to make the scoops and a silicone mold for the four stacks. I'm just finishing casting the final stack. Need to use up my silicone, it's getting some age and thickening up making it really hard to get the air bubbles out of it.
Starting to run out of details, paint won't be too far down the road.
