Nein, das ist leider nicht möglich, da die Hardware nicht die nötigen Voraussetzungen bietet.<br />

==Can I use the governor in combination with a standard (multi-wire) receiver? Why not?==
The governor can only work in combination with a serial line receiver. This is for technical reason:
* when using a multi-wire receiver all ports on MICROBEAST PLUS are occupied already. There is no free port left to connect the motor speed sensor.
* also there is no free port for the throttle output where the ESC must be connected to
* in addition to control the governor we need the throttle channel (or other type of channel) from the radio. But with a multi-wire receiver we only have the 5 channels for roll, pitch, rudder, ... there is no throttle/additional aux channel.<br />
<br />
So in summary with the Standard receiver layout we would need at least 3 additional ports on the Microbeast which are not there, unfortunately. Reasons are that governor function was implemented after MICROBEAST PLUS was designed, but also it would make the device much bigger and more complicated when adding 3 additional ports. The benefit of making MICROBEAST PLUS bigger would be little, as today most radio brands offer some sort of serial wire receiver. And serial wire is the way to go in our opinion, as it offers much more options and flexibility in general.<br />

==How to adjust Parameter menu point I (RPM Governor - Throttle response)==
==How to adjust Parameter menu point I (Governor - Throttle response)==
Use menu point I to change the response of the RPM Governor. This determines how fast and hard the system will open or close the throttle when the rotor rpm changes. With ideal throttle response you get a very consistent rotor head speed - the head speed should recover quickly and definite but not hectic when loading and unloading the rotor head.

* If throttle response is too low the main rotor may speed up immediately in unloaded conditions, e.g. when the helicopter is descending and the RPM Governor will only give soft throttle inputs when the head speed decreases.
* If throttle response is too low the main rotor may speed up immediately in unloaded conditions, e.g. when the helicopter is descending and the governor will only give soft throttle inputs when the head speed decreases.
* If the response is set too high on the other hand, the throttle may stutter audible when unloading the motor and/or the motor rpm will kick in very hard and overshoot after the rotor head was loaded and the rpm decreased, causing the tail rotor to turn due to the immediate load change.

The height of throttle response highly depends on factors such as heli size (blade size), motor power and performance and/or the throttle response behavior of the speed controller (when flying an electric heli). If you need to adjust the throttle response, we recommend to start with the lowest value and increase accordingly. Also you should use a lower head speed for adjustment as here you can see the effect more distinct.<br />

{{QUOTE|Only increase the throttle response stepwise and make sure the throttle will not start to oscillate. Note that with nitro helicopters high throttle response can cause the motor to quit when the throttle is opened too fast. With electric helicopters changing the throttle very fast can cause the speed controller to overheat and especially hard changes from unloaded to loaded conditions can cause incorrect commutations of the ESC (depending on the type of motor) which can damage the ESC if this does not have appropriate protection mechanisms.}}<br />
