Simple Pitch Adjustment for DUC Hélices Prop

The Viking Engines display included this very interesting DUC Hélices ground adjustable prop from France. Why so interesting? Blade pitch is adjusted by inserting an allen wrench into the center of the hub; a twist of the wrench rotates all three blades at once, in sync. 

That’s it, you’re done.
