It is an original installation for ultralight aircraft consisting of two small industrial engines (motor pump, lawn mower, generator, etc.) placed in a horizontally-opposed position.

“Moody Twin Engine Mount” (PiP)

Both engines individually drive two concentric shafts by means of belts. Each shaft drives a propeller and both are individual and contra-rotating.

-From the pilot's position it is possible to stop and start the engines again as the pilot can reach the manual starter handle.
