===Why do the swashplate servos run very slowly when testing on the bench?===
===Why do the swashplate servos run very slowly when testing on the bench?===
This is absolutely normal. The movement of the stick gives the MICROBEAST only a command to control the helicopter. The sticks do no longer control the servos directly. So you cannot say exactly what the MICROBEAST will do with the servos when you push one of the sticks.

===I use servos XY. What are frequency and neutral pulse?===
Here you can see a list of collected data: [http://www.beastx.com/service_servoliste.html]
This list is not intended to be complete or accurate! Please ask the servos manufacturer about his recommandations regarding servo specs and usability in helicopters with flybarless systems.
Neutral impulse:
The neutral impulse normaly is 1500-1520µs on any servo. Only special high speed tail servos use a different impulse and are normaly fitted to a specific gyro -> Futaba gyros 760µs -> logitec gyros 960µs.
Microbeast supports all types of different neutral impulses for the tail.
On cyclic you will not be able to adjust the pulse.
Talking about 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. So if we have a unknown servo we carefully increase framerate 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 framerate and again test carefully.
NOTE: 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.
