What are frequency and neutral pulse for a specific servo?

Here you can see a list of collected data: The BEASTX servo list

This list is not intended to be complete or accurate! We can't know all servos on the market. Please ask the servos manufacturer about his recommendations regarding servo specs and usability in helicopters with flybarless or gyro systems.

• Neutral impulse: The neutral impulse normally is 1500-1520µs on any servo. Only special high speed rudder servos use a different impulse and are normally fitted to a specific gyro (i.e. Futaba gyros 760µs, Logictec gyros 960µs). AR7200BX/AR7210BX/AR7300BX supports all types of different neutral impulses for the rudder servo. On cyclic you are not able to adjust the pulse.
• Update frequency: The higher the frequency the faster the control loop will work and the more accurate the system will perform. But also the servos will be more burdened as they get more work to do and the current consumption will greatly increase.
  

If using a digital servo it definitely should be capable of more than 65Hz. Usually, if we have a unknown servo we carefully increase frame rate step by step by testing on the workbench and then fly shortly and check servo temperature very often. If there are no abnormalities like extreme heat production we again increase the frame rate and again test carefully.

This procedure can lead to damage and severe injury if not obtaining safety rules. If you want to be on the safe side go with 65Hz unless the manufacturer doesn't give you another classification. We cannot tell you the specs of a servo unless we don't have any data of this specific servo ourselves. Please ask the servos' manufacturer. We do not produce or sell any servos, we only give you the possibility to use those servos. Therefore we do not accept liability for incorrect setting.
