ENGINE VERSIONS

Generally all the Stearman airframes are the same with the only major difference being the engine installed.

I see this airplane flying over my house in Greenville, SC, occasionally. Looks great in the sky. I can identify it without looking up based on the engine sound.

Beautiul bird!
