==RPM Governor - What is this and what does it?==

==RPM Governor - What is this and what does it?== <!--T:2-->

Using the governor function you can simply preset your head speed with the transmitter, i.e. when you like to fly your heli with 2500rpm, you set your throttle curve in idle 1 to straight 62.5% in the TX. Then you just place your heli on the flight field, switch to Idle1 and it'll autonomously will spool up the rotor rpm to 2500rpm. Then you can take off and fly and you will get 2500rpm all over the flight, no matter what load condition the battery is or if your nitro motor will run lean. The governor will try to hold these 2500rpm as good as possible. When rotor head load increases, it'll increase throttle as necessary, when you unload the head and the head speed increases due to aerodynamic force, it'll decrease the throttle automatically. Typically this is a lot better than only controlling the motor with static curves made in the transmitter. And next time, again you will get those 2500rpm when flying the next battery/fuel tank, although this battery might be old and voltage is slightly different or the nitro motor may run more rich or lean.<br />

==Is the RPM Governor function also available for MICROBEAST (device with silver aluminum housing)== <!--T:3-->

<p>No, unfortunately this features can only be offered for MICROBEAST PLUS and MICROBEAST PLUS HD. For other devices we can't offer such feature due to limitations of the hardware.<br />

==Electric RPM Governor - After setting up and enabling the RPM Governor the ESC does not arm anymore when I power up the unit==

==Electric RPM Governor - After setting up and enabling the RPM Governor the ESC does not arm anymore when I power up the unit== <!--T:4-->

- Some ESC do not arm when the throttle value in the radio is too close to the motor starting position. When adjusting throttle endpoints at Governor setup menu point B this was intended, so the system does "know" at which point the motor starts and additionally the system can determine the throttle positions of the transmitter. Anyhow if this does not work with your ESC and it won't start there is no other option than increasing the throttle endpoints in the transmitter again (after the positions have been set at Governor menu points B and C!) just until the ESC will initialize. Anyhow MICROBEAST PLUS knows at which point the Motor will start as endpoint have been set before. But note that now the rpm setting will differ from the given table of the MICROBEAST PLUS ProEdition manual, as you stretched the throttle range of the transmitter. So the given percentages may not fit to the desired rpms and the percentage for autorotation bailout mode may change. Use Governor menu point D to check how MICROBEAST interprets your throttle curve values by watching the Status LED color in the different flight phases at menu point D.

==Nitro RPM Governor - When recovering from an autorotation using the autorotation bail out function the throttle increases up to nearly full throttle and stays there==

==Nitro RPM Governor - When recovering from an autorotation using the autorotation bail out function the throttle increases up to nearly full throttle and stays there== <!--T:5-->

Nitro helicopters react very sluggish during rpm rampup. Especially when the clutch is worn out it can take a lot of time until the rotor gains full head speed while the motor already runs at full speed, trying to spool up the rotor. This will cause the RPM Governor to stay at full speed as it detects the desired rpm seems to be faster than the helicopter allows. So you need to prevent the throttle from opening completely during spool up by decreasing the Governor quick change rate (Parameter menu point K) to a value that represents the maximum speed the helicopter is able to ramp up the throttle.<br />

==How to adjust Parameter menu point I (RPM Governor - Throttle response)==

==How to adjust Parameter menu point I (RPM Governor - Throttle response)== <!--T:6-->

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.
