Title: Prather Reverse Pitch Prop Gauge
Post by: Crist Rigotti on May 27, 2009, 06:51:46 PM

I took a regular pitch gauge and turned into a reverse pitch gauge for our electric pusher props. I simply turned around the face, attached a new pitch scale, which I drew up using my CAD program, attached the arm, then notched the arm to clear the screw. I've included a .pdf of the new pitch scale full size.

I thought you could put the pitch gauge next to a mirror and measure a pusher prop that way. ;)

Alan, I am worried about your sense of humor.  Coincidentally, I posted much the same observation on SSW just now.

Well I like to think I am a clever fellow y1, but in actual fact, I had just changed my tractor APC12-6E for the pusher APC12-6E on the ENobler and to my surprise  n~ my lap time went up--- quite a bit actually. So when I got home, I pulled out my Prather Pitch gauge, mounted the pusher prop and then began to scratch my head. Then I realized that the universe isn't chiral symmetric, and neither was my Prather. Now if I could only change the pusher into antimatter, then to a pretty good approximation I'd be ok with the pitch gauge.

But since I am only a sport flyer ;), I decided to take a nap. Z@@ZZZ

I had an antimatter prop once, but I didn't have anything to carry it in.

Wow, a honest to goodness hijacked thread!
