Yes, but they don't have a lot of power... here is Bruce's with a Baker fan

I would make two observations regarding this:

First is that the Baker fan with its flat paddles offers significant resistance, far more so than a propeller that cuts through the air.

Secondly, Bruce's engine is not hitting on every stroke by far (or rather every other stroke, as it is a 4 cycle), so there is still a lot of potential energy that engine is not yet applying, thus it hasn't nearly reached its max power threshold yet.
