The Corsair82: 82% F4U-1A Corsair

It even sounds like a Corsair

The Corsair82 is designed to use the Pratt and Whittney R-985 Wasp engine. This engine is 82% the size of the Pratt and Whittney R-2800 Double Wasp engine, which is the primary reason for choosing that scale for the airframe. The advantages of the R-985 include relatively low cost, high availability of powerplants, parts and maintenance, and very high power. The R-985 is probably the most common radial available. And you can't get anything close to that kind of power for three times the price.

One of the earlier 75% scale versions of the Corsair82 called for use of a Russian radial. But they have several disadvantages, especially for a replica. For one thing they turn the opposite direction from a Pratt & Whittney.

Of course you can put any engine you want in your own replica, but there is nothing like the sound of a radial engine. You can hear it right here.

In Mid 2006 I bought an engine from a guy in the Amsterdam, NY area. It has a few hours on it, but should be a good engine for test flight. I built a test stand so I could test the engine and prop before I actually test fly the Corsair82. I don’t want to be test flying an engine for the first time in an airplane being flown for the first time.

That is a big motor.

I hope it is built strong enough!
