As you all know, Stephen does a real nice selection of 3d printed fittings. I had a dilemma recently, and asked him if he could do a specific thing for me. After some time finding plans etc, and waiting for me to supply sizes, I got what I wanted!
The Piper Cub plane has a specific engine, a Continental, with 4 cylinders protruding from the cowl, nobody does a nice scale model of this, they are usually just some bits of balsa and plastic stuck on the sides. Well I have nice ones now, Good eh!
And just for good measure, the last picture is the real thing that I used for reference. There should be heat shields over the cylinders, but then you cant se them, so I'm leaving that off so all can admire what I have!😊
