Where did you find your reference shots? I've been thinking of modelling a motor of some kind but am having a hard time finding reference. Looks gorgeous! Keep it up!
Looking awesome,I especially love the materials!Oh and by the way its radial engine not rotary .PSI'm dumb,actually it is rotary engine but looks similar to radial, didnt know radial engines were used in planes.
The confusion might come from the fact that the Wankel engines are usually called rotary engines since the "piston" or moving part is "rotating" not translating like a regular piston.There are actually engines which are called rotary engines which share the radial pistons arrangement with the radial engine. These differ from radial engines in the fact that the crankshaft is fixed and the movement of the pistons case the entire engine to rotate. This arrangement is usually used in air cooled engines since it aids cooling.Great model BTW, love the textures and the look of the render.
