Hey Rusty,
I also considered using fabric ducting but decided that it would weigh just as much and cause more drag and not be any easier.
You might try using the liquid foam. Its comes in any shape you want, sands very easily and dosen't make as much mess as the pink foam I used to use.
Cheers,
Dave Leonard

Where do I find some 5" diameter tubing that will stretch to 12" diameter
(or 9" x 10" square)?

If you find one, make sure you do it BEFORE
I have to make mine out of fiberglass :-)
Speaking of
wacky ideas, I briefly thought about using some sort of airtight fabric to make
the duct. I imagined having it sealed to the core, then attached to a
removable cone that would mount inside the air inlet. Unfortunately, I'm
not sure this would be easier to make, and you'd have to worry about it rubbing
on the cowl, and getting holes in it. I haven't completely given up
on this idea, partly because I hate fiberglass so much, but mostly because I
want to make Ed try to calculate it :-)

so much blue foam that I look like a
smurf)
