Johnny (shop foreman) said he once replaced a motor, and during the engine breakin once replaced, the No.2 rotor went out on the fresh motor within the 1st 25 min. Had to replace a REPLACED motor!!

Now rotary in general aren't junk. They're pretty cool. The only thing that limits them is the crank. If you can get a crank made long enough, hell you could get a tri-rotor, quad rotor, etc. The housings just bolt together like a jigsaw puzzle.

The owner, Bob Mears, is building an airplane, a Spitfire replica, and he's putting in a tri-rotor engine in it.

That should be cool.
