Talk:SMA SR305-230

Info needed -- materials?
It would be helpful if the basic materials used for this engine could be noted. For example, is the crankcase cast iron or aluminum? Are the cylinders and pistons steel or aluminum? Just the basics -- this info is well known for other production aviation piston engines (e.g., Lycoming, Continental). And given the much higher Mean Effective Pressure that this engine operates at, it is important to note the basic materials in order to assess the potential reliability and longevity.
