SETUPMENÜ D - Ansteuerfrequenz Heckservo
Similar to swashplate servos frame rate at Menu Point B you can select the update frequency/update rate 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 at least 270Hz. With high update rate, the system will recalculate movements more often and in consequence will send commands to the servo with a higher frequency. This results in better positioning and more locked in feeling. Of course, this will cause the rudder servo to make more movements at a given timeframe. So in case the servo is not built for this kind of application, this can cause a high power consumption of the servo and cause the servo getting very hot. When this happens, reduce update rate immediately to prevent your servo from getting damaged. Only go as high as recommended by the servo manufacturer, or reduce frequency to an acceptable level, in case the servo is not capable of handling such high frequency in field use.
- When using a servo that allows a higher frequency as MICROBEAST ULTRA can offer, please select the next lower frequency that is closest to the given frequency or set a custom frequency with the StudioX app.
- Using a lower frequency is always possible. Only 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. Also we can't guarantee the accuracy of this data. Ask the manufacturer of the servos or your servo dealer for detailed information.
- 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.
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!
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 at SETUP MENU point D. Please note that depending on the rudder servo pulse width chosen at Menu Point C, you may not be able to select 560Hz! Servos with Standard pulse width of 1500/1520µs can only run at maximum frame rate of 400Hz.
| 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 with StudioX, 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 StudioX app
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. Using a custom frequency you can go up to 400Hz frame rate for rudder servos with standard pulse width of 1500/1520µs. Usually this is plenty enough even for the fastest servos on the market. Going higher is not possible due to technical reasons (the servo pulse at maximum deflection would not fit into the frame properly!). If you want to get top notch performance, we recommend using a servo with 760µs pulse width. This allows frequencies up to 600Hz.
