Dynafocal or Conical

Explaination.......

On a Dynafocal mount, the extended line of the mounting bolts meet at the C/G of the engine. On a Conical mount, the bolts are all parallel to the thrust line of the engine.
 
I believe the type 2 mount was designed primarily for the Twin Commanche installation. The focal angle of the mount is 18° vs 30° for the type 1.

This is correct. Because the Twin Commanche used substantial prop extensions, the C/G of the engine/prop combintion is further forward.
