Open Source Projects

"For Educational Purposes Only"

PRA proposes to provide all of the Solid work drawings, Parts list, Software, Instructions, CNC code will be provided to either create your own or Rotorland USA, LLC will have them made for you. In either case, you will want to buy the parts from Rotorland USA, LLC as we plan on buying volume and holding it in inventory reducing the cost to members.
