This is a six cylinder, two stroke, air-cooled aircraft engine that I recently modeled in Autodesk Inventor. I will be uploading this model soon in my GrabCAD account, including the G/NC Codes for each unique parts. This will include CNC Simulations in HSM Works 2016. For those Solidworks fans, I will include a 2016 version model with the SolidCAM prt files. My net is quite slow, so please bear with me.
