An Italian company named MWFly has come up with an intriguing way to handle the problem of torsional loads on small geared engines. Rather than a clutch or a dog gear to absorb the loads, MW's idea is to reduce the loads in the first place so it has developed a variable compression ratio design that backs off compression at idle and low speeds, but allows it to return to high compression when more power is needed.

In its first showing in the U.S. market at Sun 'n Fun this week, MWFly showed AVweb how this clever idea works. In this exclusive AVweb video, the company's Guido Fantini said the variable compression ratio approach reduces weight and parts count without a loss in performance.
