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

- 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 additionaly 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.

- If MICROBEAST PLUS does not get a valid signal from the receiver within 2 seconds it'll lock the throttle and set it to the throttle failsafe position. I.E. this can happen when the receiver does not bind to the transmitter signal immediately when powering up. With some systems this can take a few seconds or this can occur when the transmitter is positioned too close to the receiver. So if the ESC does not arm in this condition probably the throttle failsafe position is not set correctly. Please enter Receiver setup menu and reset the failsafe position at receiver menu point N.

Note: After performing adjustments at Receiver setup menu both the Governor and AttitudeControl will be disabled.
So when using one or both of these functions don't forget to enable them again at Parameter menu point L and Setup
menu Point N. Especially in respect to the Governor function watch out not to switch on throttle as long as the
Governor function is disabled at Setup menu point N. Otherwise the motor will start to run very abruptly when
switching to idle up as you have direct motor control from the transmitter.

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

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.
