Can anyone give a brief explanation of the conical engine mount, and why it's built the way that it is. Not that I intend building one, just curious as to why the mount points are turned inwardly and appear to be focused at some point - is this a theoretical focus point that has the CG of the engine at it's focus?

That's the dynafocal mount. You've got the right idea about the reason. There are at least 2 versions; the 2nd type is for some engines used on twins that have extended hub props (cg is farther forward, and the converge point of the bolts is also).

The conical mount has all 4 bolts parallel.
