        Matt,

        These engines are so small you could almost mount them side by
        side both feeding into a small PSRU.

        Doug,

        You could arrange two of them horizontally opposed -- just bolt
   the
        bases together. It looks like there might be enough room to have a
        pulley right in the middle for prop, with a belt coming off each
        engine to the prop pulley in the middle.

        That would probably fit under the cowl of a small sportplane. In a
        real small cowl, you might have the carbs or exhaust sticking out a
        bit, a la J3 Cub.

        Regards,

        Gordon.

We had discussed doing something similar.  I don't think it's a bad
idea, but it wouldn't be as light as if you could actually combine the
parts into a 2 rotor engine..
