See optionals from Components tab below.
The PR1-P, controls and keeps the engine speed constant by varying the propeller pitch. Operation is very simple: you set the desired engine speed and the PR1-P will do all the work, displaying the target speed and the actual speed measured by the motor. It is completely adaptable to the characteristics of the various propellers thanks to settable parameters that allow to obtain the maximum adjustment precision.
Thanks to its patented hardware and software, the PR1-P is able to maintain the target speed with an accuracy of +/- 20 RPM, just like a propeller with hydraulic regulator.
PR1-P and PR2-P are the only regulators that can be used on very fast electric propellers (propellers with travel time from fine to coarse of 2~3 seconds).
Main features:
  • RPM setting using the knob or the INC/DEC switch
  • Min and max pitch LED indicators
  • Propeller test before take-off
  • Hour-meter with the effective working time of the propeller electric motor
  • Possibility of connecting an external switch to adjust the pitch from the cloche
  • Possibility of connecting an external potentiometer or Flybox lever
  • LCD with backlight and coated glass
  • Safety switch to exclude electronic control in case of failure
