SETUP MENU D - Rudder servo frequency

Jump to navigation Jump to search

As with the swashplate servos at Menu Point B you can select the update frequency for the rudder servo here. For best tail gyro performance the rule is: the higher the better! A good rudder servo should be capable of running with at least 270Hz. With high update frequency the system will recalculate correctional movements more often and in consequence will send new commands to the servo with a higher frequency and allow for better positioning and more locked in feeling. Nevertheless, this will cause the rudder servo to make more position changes at a given timeframe. In case the servo is not built for this kind of application this can cause an unusual high power consumption of the receiver power supply and cause the servo getting very hot. When this happens, reduce frequency immediately to prevent your servo from getting damaged. Only go as high as recommended by the servo manufacturer, or even lower when the servo is not capable of handling such high frequency in field use.

When using a servo that allows a higher frequency as MICROBEAST PLUS offers or that allows a maximum frequency which is not choosable, please select the next lower frequency that is closest to the given frequency or set the frequency with StudioXm PC Software or mobile App. Note: Using a lower frequency is always possible. Only too high frequencies can damage the servo and/or will cause the servo to not work properly. Here you can find a list of parameters for the most common servos. Please understand that we can not list all servo types. We also can not guarantee the accuracy of this data. Ask the manufacturer of the servos or your servo dealer for detailed information.

Warning.png If you do not know the maximum pulse rate tolerated by your servos do not select more than 50Hz driving frequency. A higher driving frequency can lead to failure of the servo!
With high frequencies, some servos run in a jerky manner, especially the fast ones with coreless or brushless servos. This is due to the high update rate that the servo receives. This is not critical and will not impact flight performance.

Adjustment on the device

To select the desired servo frequency, move the rudder stick repeatedly in one direction until the Status-LED lights in the correct color. Please note that depending on the rudder servo center pulse width chosen at Menu Point C, you may not be able to select a frequency higher than 333Hz!

Status-LED Rudder servo frequency
purple 50 Hz
red flashing 165 Hz
red 270 Hz
blue flashing 333 Hz
blue 560 Hz

Note: When you set a different frame rate from the StudioX app, the Status LED will be off. You can change back to a preset by tapping the rudder stick as described, but this will remove your custom setting!

Setup with StudioXm

Choose a preset frequency by clicking one of the provided buttons for Menu Point D (Rudder frequency) or set a custom frequency by directly changing the value with the dial or buttons.
