That looks like a lot of fun! What's the difference between feathered and unfeathered propellers?

^ looks like the direction (face) of the prop blades, one is very flat agains the oncomming air and the other looks to cut though the air with minimal resistance?

Feathered - slow and smooth?
usFeathered - fast but bumpy?

looks like fun

I had the labels backwards on the photos. You basically feather a propeller if you shut down the engine you reduce drag and prevent the propeller from windmilling causing more damage to the engine.
