Oh I didn't notice that one. I have been referring to the Sky Scout drawings forthe wing bracing, so I hopefully I've drawn it correctly.The wing section shown for the Air Camper isn't complete enough to construct theribs. That's the reason for checking the Sky Scout drawings.The ordinates given for the airfoil plot out in a less than smooth curve to put it mildly, so I searched online for a more carefully composed set of points to enter into CAD. The Holcomb's Aerodrome web page gives a set of ordinates that create a smooth curve when a spline is drawn between then. They provide the ordingates in either XLS or text format.

Has anyone tried an alternate location for the radiator on Model A powered Piets?Is it possible to locate it below the engine at an angle that follows the originalcowling design?Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Wed, 19 Apr 2006 07:53:57 -0700

That's what I had in mind. But before I decide the plane should revolve aroundthis alternate cooling arrangement I should ask: Is the lack of forward visabilitydue to the radiator mounted above the engine a real issue? I like the lookof the radiator above the engine. It works with the lines of the plane.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Wed, 19 Apr 2006 15:31:20 -0400

Sure they have, the sky scout has it mounted on the lower cowl exactly as you suggest.Gene ----- Original Message -----

However,I had my radiator custom built to be the width between the fwd cabane struts, and about1/3 of the way down, leaving some visibility under the radiator. The top tankwas behind the leading edge of the wing, in a cavity that I built in the bottom of the wing.

Subject: Re: Pietenpol-List: Model A radiator locationThe radiator that Bernard mounted under the engine was used only on the Model A powered Scout...it worked really well... I restored the airplane about 40 years ago and it is still flying today. I doubt that it could be made to workon an Air Camper, because the firewall is vertical...on the Model A Scout, thefirewall slanted back, allowing the cooling air from the radiator to travel up and back to exit through louvers on the top cowl ahead of the instrument panel. Bernard didn't "reject" the radiator installation...he just didn't buildany more single place airplanes.Forrest LovleyJordan MN________________________________________________________________________________Date: Thu, 20 Apr 2006 09:38:12 -0400
