Yup all the same props, which did not have the blade profile of a 13 foot Ham Std. either.
Which is why all electric and rubber band FF models use glow profile props... because they are not much less effective. [&:]
Sorry if I don't quite understand or agree.

OK FOUND THE ADJUSTABLE PROP!! Called a Vario-prop. Can be found here among other places.

I have never ordered from them, they just showed up on a google search. I lied about the price, too. Looks like about $30 plus shipping gets you going.

The issue we deal with is generating good thrust in the RPM range of most park flyer electric motors. That's why they have big paddle-shaped blades. A scale profile Ham-Std. for your corsair would not develope any appreciable thrust.
When the electics first started in the 70's they all used the same props. Though the large prop area helps it is not that much more effective. Take for example the Air Hogs compressed air model planes, they use a prop very similar to the 6-3 prop used for 1/2 A glow. They turn much slower RPM's than an electric yet they move the supplied model well. However that model could also be powered by a .010 glow engine.
