I had only considered using outside air from an armpit scoop. I'm just ready to build the housing for the heater core, so I'll build it so that I can also use the recirculate option, if need be. Thanks for the tip.

It works very well, but Ken is right. On very cold days when I go very high and it's even colder, the engine is running so cool that there isn't much heat. If you live in the Midwest you would probably need the recirculation option. -- Perry Mick http://www.ductedfan.com >> Homepage: http://www.flyrotary.com/ >> Archive: http://lancaironline.net/lists/flyrotary/List.html --- Outgoing mail is certified Virus Free.
