Dear YKW and others, The sport pilot issue will help some of us who can pass a physical butjust can't afford a $125.00 physical. I finally located one 50 miles awaythat does it for $80.00. Thats still 2 much. Anybody know what is theearliest you can arrive and set up camp at Brodhead? Thanks,Bill > Get ready Brodhead, here we come. >>>________________________________________________________________________________Date: Thu, 15 May 2003 15:25:13 -0700 (PDT)

The prop that Orin Hoopman drew plans for, dated 3/3/33, was for a 76 X 48 prop. I believe this is the size that B.H.P used on his Model A engines. It's called a 'Paddle Blade Prop', because chord is quite a bit wider at about half way out the blade. These are the plans I used to build the prop for my Model A, but mine was 75" dia. Doug Bryant used a 76 X 48 on his Piet. Stock engine, I would get about 1650 rpm during ground run - up, and unloaded in cruise flight I would get close to 1800 rpm. These are close to the numbers that Doug got. Ken Perkins (Kansas City) thought we were running too much prop for the Model A, and he uses a smaller dia and pitch, but I don't remember what it was. Therefore he would run it at a higher rpm, and take advantage of the higher horsepower above 2000 rpm. His Model A has a pressure oil system, and that is DEFINATELY the way to go. The ol' Model has potential to make good reliable power, but it has to be built to take advantage of this potential...such as pressure oil system, improved induction system, forged pistons, and a better prop flange / hub, to mention a few.Chuck Gantzer________________________________________________________________________________

The concensus by far was a 78/42. On the basis of this I ordered that size from Chad Wilie (sp?) and was pleased with the quality. I am turning 1650 static and anticipate 18-1900 in the air.
