Please note the RPM Governor function can only be used in combination with a single-line receiver or Spektrum remote satellite. When using a receiver with standard connection layout there is no option for connecting the rpm sensor and throttle servo/ESC and no connector for throttle control.
Preparations for RPM Governor usage (optional)
To use the RPM Governor function of Microbeast PLUS it is necessary that Microbeast PLUS is able to measure the motor speed. Therefor the separate purchase of a motor rpm sensor is required. Additionaly you need the rpm sensor adapter cable (Order Nr. BXA76401) to be able to connect the sensor to your Microbeast PLUS unit and power it from there. When using an electric helicopter it is possible that your speed controller already supplies a rpm signal output. In this case no additional accessories are required as you can directly connect this signal wire's connector to the front pin board of Microbeast PLUS.
When using a nitro helicopter remove the servo horn of the throttle servo before powering up the system or do not connect the throttle servo linkage yet, in order to avoid blocking and in consequence damage of the servo due to incorrect setting.
Using an electric model ensure that the speed controller is programmed correctly and that the travels for the throttle channel have been adjusted in the transmitter if necessary. Note that the speed controller itself must not be operated in a (heli specific) governor mode, but must be operated in a simple motor control mode that allows to control the motor rpm as direct as possible. The throttle signal must not be filtered by the ESC and should be processed as linear as possible. This ensures that the control loop of Microbeast PLUS can govern the motor rpm optimally. Also you should switch off any "soft start" function, as this will be done by Microbeast PLUS. Some electric speed controllers offer a special „External control mode“ or „Flybarless mode“ which meet these requirements. If your motor controller does not have such a mode, we recommend to select a mode that typically offers such behavior, like a some mode for fixed wing aircraft. Note, however, that no brake function (which is required for electric gliders) must be active and that the throttle response should be set to maximum speed, if such a feature is provided.
Pay attention to your own safety and the safety of other people and property in your vicinity when using our product. When using helicopters with nitro/gas engines make sure that the motor will not start when making adjustments to the system. When using a gas engine always keep the ignition system deactivated!
