I love anything that turns and twists. I am not talking about bedtime activities…..but stairs and propellers. <G>
I am putting on an adjustable pitch propeller on my gyrocopter and just line it up in front of a stairs…and said….YEEAAAA

Is it adjustable in flight?

didit: Yep..its an inflight adjustable prop. It is working slick.
When I was deeply into RC modeling, I built two scale models of the Russian Sukhoi SU 26 competition aerobatic monoplane, one at 44" wingspan and the other at 72".
I was a big fan of the Sukhoi then. It had been winning international competitions. We made a pilgrimage once down to Pompano Air Center in Florida to see the full sized ones they had there. Here is a pic of the SU 26.

Outfitted with a powerful 9-cylinder radial engine, it is pulled by a constant-speed variable pitch prop.
Barely visible in the above pic, the pilot has plexi panels at his sides, and a large plexi bellypan, so between the large canopy, the clear side panels, and looking through his legs through the bellypan, he has 360 degrees of vision.
They are probably outperformed by today's competitive planes, but an SU 26 will roll at a rate of 400 degrees per second. Just look at the size of those control surfaces. Impressive.
There is a site you can go to (probably on YouTube now) where videos are shown looking from the cockpit when the plane is performing gut-wrenching aeros.

See the triangular thingies on the small booms aft of the wingtips? Those help the pilot get the plane right when doing up and down 45s, and perp climbs and dives. The horizon is aligned with the appropriate piece of the sight array.
One of the members of Pink Floyd flies a 26, and it is all done up in pink trim.
Stan that prop looks like it would fit well on a P-51 Mustang. Wicked looking.Do I see chrome? extremely cool. stinky
stinky: Thats just the polished aluminum pitch motor and commutator rings. This prop is electric controlled. Having a variable pitch prop on an aircraft is like having a gearshift on a vehicle.
I will be able to have a climb like a "homesick angle" when taking off with the flatter pitch...and then add pitch as my airspeed increases. It will save on fuel and the engine will be running much slower.
