	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.		: If using a digital servo it definitely should be capable of more than 65Hz.

	Anyhow the color is not a fixed value that is a must to reach. If you get blue you have something similar to 80% usable servo throw. The further you can go the higher the value will be. So everything from blue upwards will give a good resolution and you won't feel any disadvantages. If using good, precise high class servos, strong and with fast speed you even can fly with only red LED without any noticeable difference. Also rotorblades (flybarless blades or not) can make a difference.		Anyhow the color is not a fixed value that is a must to reach.

	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.

	If parameter B is set to blue and the tail gain is switched to heading lock mode you can see by the status LED at which tail stick position the maximum possible rotation rate on rudder will be reached: At that specific tail stick position it will start to flash. At this point the maximum gyro controlled rotation rate is reached. By increasing the stick throw any more the LED will go off. At this point the rate control is switched off and the tail will spin freely. Here the only limit is the maximum possible tail pitch throw and normaly the tail will spin ultra fast. This can be used for example for performaning tail slides or turns with very fast spinning tail. For normal flying around this is not recommended as you may accidentaly steer into the uncontrolled area and the tail may spin too fast or very uneven.

	The roation speed is only determined by the length of the stick signal (and especially has nothing to do with your cyclic pitch adjustment at setup points J or L and also has nothing to do with the cyclic pitch when steering cyclic on the ground!). So increasing/decreasing the stick throw, mostly done by increasing/decreasing servo throw or using Dualrate in the TX for the specified function, will increase/decrease roation rate.

	The presets in parameter B are nothing else than different preset dualrate/expo curves inside the MB. When using these it is recommended not to change the output signal in the TX as especially when using expo this will bend, compress or stretch the curves leading to very strange flight behavior (it just is not like adding 5% of expo as the curves between TX and Microbeast will multiply and not sum together!) If you like the feeling of course you can do this. For example a slight increase in stick throw for increasing the roll rate will not significantly deform the Microbeast's internal curve and can be done with no problem. But easiest thing would be to switch flight behaviour to "blue=TX" and adjust the curves in your transmitter as you like (therefor I'd suggest to start with 70% D/R and 25% expo on cylic and 85% D/R and 40% expo on tail).

When setting parameter B to "blue = TX" these internal curves in MB will be disabled. So 100% stick should give 100% rotation rate. This may vary depending on TX brand as any manufacturer use another signal output as maximum. So this can be at 107 or 110% or also at 95%. Manufacturers calculate expo curves different, so we can't tell you what our preset curves correspond to which TXs expo values as we use our own expo and there is no data available for comparing. We did outfly these values and programmed them in the source code so we can't tell what these are in Futaba or JR percentages.
