Enstrom Helicopter, a Michigan-based helicopter manufacturer, is developing a new RPM governor for its piston helicopters, the company announced Thursday at HAI’s Heli-Expo in Atlanta. 

RPM governors are designed to help helicopter pilots automatically maintain a constant RPM in their rotors. Enstrom says its RPM governor uses a digital controller and has a fast-acting servo motor that accurately controls the RPM. Todd Tetzlaff, Enstrom’s incoming CEO, says its design was driven by safety and convenience.
