Today our engineer has the basic design for SC50.1's working bits hammered out.  

We will continue refining and testing them using computational fluid dynamics (CFD) and finite element analysis (FEA) until we have a running prototype in order to make sure that things will work as they should. 

When they should. 

And most importantly - stay where they should.

(It is always a challenge getting all those things to coincide on a small piston engine revving to 10,000 RPM or more...)
