About Us

Hello. My name is Jim Czachorowski.  I am a Pilot and a Mechanical Engineer.  I started my Flying Career in the Military.  General Motors gave me my first Engineering  job.

My interest in Experimental Aircraft started with the Stewart S-51.  I designed an Accessory Drive Case to convert a Chevrolet V8 engine to power the S-51. I own several CNC Mills and Lathes that were use to construct the parts.  Currently, there are 6 aircraft that utilize my accessory drive case.  Brass Monkey Inc was formed in order to build these parts.

I am currently designing parts for the Vans RV10.  Stayed tuned.
