Santa Claus was my friend
It is a varialble pitch propeller, I love it.
One of my buddies in our modelling club is very experienced in3-D-printing. He builded himself a 3-D-printer and done the tail gear for me.
There are two differend options, the left is made from the Wylam-drawing, the right I saw on an pic.
I use currently the right one, in our german "warbidforum" is a guy who is very often in Bangkok, Ihope he can help.
