This is another model engine I've been working on for the past couple of months. It's modelled loosely after the Whittle V8 airplane engine. It has 8 cylinders in a V configuration, bore and stroke are 3/8" x 7/16". The crankcase halves are made from magnesium, the cylinders and rods are aluminum, the pistons and crankshaft are steel and the rest is brass. The flywheel is temporary and will be replaced with a larger steel propeller in the final model. I'll also be adding a permanent mount for it.
