Was there a big static rpm change after the valve seat work? I would adjust the mixture with new plugs and check the color after 5...

The 2800 sounds about normal to me for static. What is the book number for static rpm? Dana said the 3200 is at 60 mph. The throttle...

I don't see any circuit breakers that reset after cooling down and toggling the master switch. But I do see some "not FAA approved"...

I think he said " west coast". Could be Oregon or Washington.

For an airplane prop shaft the losses could be as small as the bearings, I think. Three bearings shown here, but only one additional...

Certified airplanes sometimes have rpm avoid zones. Marc's prop came off with some airframe damage but the landing was a success.

Yep. My spar failed first test also. That compression cap is a bugger.

The Questair skins were stretch formed with hydraulic cylinders, as I recall, from the Sport Aviation article.

One guy on the yahoo small engine forum flew his vertical shaft Briggs with the 90° belt drive on his powered parachute. I would think...

Cirrus floundered at the beginning with a pusher. Pusher has never seen a mass certified market, as far as I know. Cirrus abandoned the...

Long V belts can be a shaft alternative. The engine would be vertical shaft like a Briggs 810 or two- stroke mounted vertical. The belt...

Do you remember the prop rpm direct drive in static, climb or cruise? I see it is rated at 6300 rpm, but doubt that is used direct drive.

"At this point a simple mechanic is smarter at implementing something than a claimed engineer." He doesn't claim to be an engineer or...

Water pressure is relatively safe.
