MICROBEAST PLUS RPM Governor - How to setup a Castle Creations ESC

The RPM Governor function of MICROBEAST PLUS firmware version 4.0.0 does work very well with Castle Creations ESCs. The Castle Creations Phoenix EDGE series provide a separate rpm signal output, so despite the firmware with governor function there is nothing else needed to connect your ESC to MICROBEAST PLUS. When using a Castle Talon, ICE, ICE2 or similar ESC you additionally need to buy a rpm phase sensor like the BEASTX phase sensor BXA76013 so that MICROBEAST PLUS can detect the motor speed/rotor head speed of your helicopter. To connect and supply the rpm sensor with power you will also need the sensor adapter BX76401.

The Castle Creations ESC offer a special "External Governor" mode to be used with flybarless systems. Anyhow, this mode has an integrated soft start and autorotation bailout function. Therfore we do NOT recommend to use this mode, as MICROBEAST PLUS can do this on its own! Instead we suggest to setup the Castle ESC to a very simple throttle control mode which is offered by using the fixed wing "Airplane" mode as "Vehicle type" in combination with a very fast throttle response:

Of course we don't need the brake function for Airplanes:

Alternatively you may use the "Multi-Rotor" vehicle type. This will provide a very fast and immediate throttle control and thus provide maximum performance of the MICROBEAST's RPM Governor. Adjusting throttle response and brake function is not necessary here and not provided. Please note that this mode doesn't feature any dynamic limitation. Depending on the motor this can cause very high current spikes and overheating of the motor. Only use at your own risk:


The rest can be setup as you like resp. as it is needed for your motor:

When using a Castle EDGE controllers with the provided rpm signal cable, make sure the "Auxiliary wire mode" is set to "RPM out". Otherwise there will not be any rpm signal on this wire:
