A 1-cylinder, two-stroke, 10 HP lawn mower engine converted for aviation

-Two of these Rowena engines were used on the French "homebuilt" Cri-Cri.

“Cri-Cri, with Rowena engine”

-Like the Mignet “Pou-du-ciel” that used countless engines, the Cri-Cri, the new French success, has also used many small engines (smaller than those used on the Mignet), such as those used in lawnmowers, chainsaws, etc.

-Even small turbines like the outputs lately. Always with two motors, one at each end of the V-shaped uprights at the bow.
