Default RE: Roto motor 35FS

I looks good but I don't know about the specs.

They say this is an 3.5 HP engine.

Then go on to say, "20x10 6,000 RPM"

A 20x10 at 6,000 RPM is only 2.3 HP

Plus this is only 15 pounds static thrust at 56 MPH.

Since a lot of 30cc two strokes put out 3.5 HP I'd be inclined to believe the Roto 35FS only has 2.3 HP
