Well my titanium came in. I think I will instead use it to make the motor mount for the 170 going in the P-51.

When I installed the CDI kit on the 170 I was blown away that the piston actually has huge cutouts on the skirt I assume to save weight. The connecting rod was clearly aluminum like someone here had said. The machining quality in the 170 was second to none.

One thing I noticed is that the compression ratio with the CDI head appears to be less. Does this mean I can run high nitro (50%) without changing compression?

Anyway, time to get a carbide tipped band saw blade to make these motor mounts.
