Thanks for all the information and the links....however, the "Wright Flyer" seems to have used a horizontally mounted engine.
I did some additional research and the engine I'm looking for can be seen @: Museumvictoria.com.au Wright Model 'A' 1909 Aero Engine. This is a vertical, 4 cylinder inline engine....B/S= 112mm X 111mm, 30 HP @ 1,300 RPM, 4,372 cc, Compression Ratio: 4.165.... Built by Bariquand and Marre. Wish I could provide photos, and direct links. Just wondering if this was ever done as a scale-model, and if yes, who might have the drawings.
This Straight-4 doesn't look too difficult, and I just want to replicate the "look" of this vintage, Aero engine. Drawings would help. I'm wondering if the wright Bros. Museum might have just the engine drawings. I have no interest in drawings for the actual airplane.
