Dear Paul,

Thank you for editing and distributing such an informative newsletter.
I would like to ask whether you (or other subscribers) know of a
reduction box which combines the output of two rotaries into one prop
shaft, while enabling individual operation / sut-down of each of the two
engines?

Thank you very much, again.
Ronen.

I don't know of one. Sounds like a fun project. Is this for an aircraft
or a boat?

Paul Lamar ...No rotor no motor.

Paul,

Seems like I remember a couple of South American brothers had
something along those lines that was featured a few of years back in
one of the aero magazines

Terry

The Leon brothers, Ruben and Carlos's built a twin Suzuki powered Cozy from
Venezuela, they flew this plane all the way to Oshkosh!
They squeezed two engines side by side, coaxial drive shafts turning
counter-rotating propellers, at 8000 ft it will do 110kts on a single
engine.
