...is generally not the way to make airplane-in-flight photos look realistic, however, when I heard that this 1937 Piper Cub J-2 was going to demonstrate a one-bladed prop, I had to bump up the shutter speed. Photos were made last month during the 28th annual Sentimental Journey to Lock Haven PA, the home of the Piper factory from 1937 until 1984.

Here is some info on this contraption if you are interested.

I know, it is spelled "propeller", no excuse.

That is a weird looking prop. I guess it works, but why would you want one?

According to the info I picked up that day, the '37 Cubs (and many other lighter single pilot sport aircraft of that era) were powered by the 40HP Continental engine. Many two-place Cub pilots were wishing for shorter takeoff rolls and a better rate of climb. This "Everel Propeller" was the answer. The claim was a 25% increase in top speed, 30% increase in rate of climb and a 50% reduction in takeoff roll. The folks in Lock Haven did a side-by-side demonstration with a normally propellered J-2. The one-bladed version did appear to perform better in all areas mentioned. Made me a believer.

Good shots...but you would think that having only one blade would put a great strain on..well everything connected to it.
