Throttle control unit PR1-P

for aircraft

Overview
The PR1-P controls and maintains engine speed by varying propeller pitch. Operation is intuitive: set the target engine RPM and the PR1-P performs regulation, displaying both the target RPM and the actual RPM measured on the motor. Adjustable parameters allow adaptation to different propeller characteristics for precise control. The patented hardware and software maintain the target speed within +/- 20 RPM, delivering accuracy comparable to hydraulic governors. PR1-P and PR2-P are suitable for very fast electric propellers with a fine-to-coarse travel time of 2–3 seconds.
