To leave heat on all the time , you wouldn't get everything out of your engine. Icing has very little to do with flying in summer or winter. In winter , cold air can't hold that much humidity, to turn to ice. In summer, you have those white sky days due to lots of water vapor in the air. The most dangerous days are when the dew point is very near to the air temp. Dew point is what temp. you need to drop the outside air to, in order to make it rain. Where the air can't hold any more water. Warm air hold lots of water,,,cold air holds relatively little water. Take note of the Dew point on a flying day walt evans NX140DL ----- Original Message ----- From: John Smoyer To: pietenpol-list@matronics.com Sent: Friday, February 06, 2009 9:08 AM Subject: Pietenpol-List: Model A carb heat Most of the Piets I've seen run all the carburetor intake air through a heat muff mounted on the exhaust stack. It's like carb heat is always on. Is there any reason to set up an adjustable control so that some or all of the air to the carb is unheated?

I got this 'book' from Dale Johnson, who, if I remember correctly, had contact with the family of Al and got permission to do with the material as he pleased. I scanned the material a bunch of years ago so more builders could get their hands on it. There is also an old doc called Simplified Propeller Design for Low Powered Aircraft that you could put on the DVD if you like - I'm pretty sure that it is a government doc and in the public domain Ciao Kirk On Feb 6, 2009, at 2:05 PM, Gary Boothe wrote: > Thanks!!....eagerly awaiting=85. > > Gary Boothe > Cool, Ca. > Pietenpol > WW Corvair Conversion > Tail done, working on fuselage (endless metal parts!) > (12 ribs down=85) > Do not archive > From: owner-pietenpol-list-server@matronics.com [mailto:owner-pietenpol-list-server@matronics.com > ] On Behalf Of helspersew@aol.com > Sent: Friday, February 06, 2009 11:45 AM > To: pietenpol-list@matronics.com > Subject: Pietenpol-List: Prop carving CD > > Hi Gary, > > I am still working on finishing my Prop Carving CD, the > instructional essay with diagrams and photos.
