Engineer Roland Parodi has modified Honda engines with a new block and distribution.

-The HP-45 is known that with only 500 cc gives 45 CV at 8,000 rpm, reduced to 2,800 rpm for the propeller. It is a four-cylinder, four-stroke engine.

-The HP-60 model gives 60 hp. And there were projects for 75, 80, 100 and 130 CV but they did not prosper.
