You only have to adjust one direction whether left or right, it doesn't matter. Important is to exactly adjust 6° as this teaches the unit the servo throw. And as said the color is of minor importance but you should try to get to blue as close as possible to achieve best performance.

===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.

Check very carefully whether all cables are plugged in correctly and all the plugs are connected properly at the correct position (Beast & receiver!). Especially in the vertical direction, not just 2 pins must sit on the header. Also make sure that the polarity is correct on all connections.

(Please do not confuse: A slight tilt of the swash plate when the heli is standing on the ground is absolutely normal when the so-called integrators are not fully discharged. This only will happen after approx. 30 seconds without moving the helicopter or touching the sticks, then the swash returns to its normal position. This also depends on the position of the throttle stick - in the middle position is the discharge at the fastest. A bug in the above named manner is present when the swash moves downright by itself to full-stop also after correcting with the sticks and only cycling power off and on can resolve this problem.)

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.
