Ok here goes after i have done some reading up on this revomix i have even went as far as emailing beast x administrator and they email me back with plenty of great info any i set up the revomix mix on my 550e and went to my field quickly me and my mate who flies 3d and WOW what a difference the tail feels 100% better even in this wind that we are having right now the tail did not drift once i can bealive it the thing just feel so solid anyway gave my mate a little go and he was the same(he has a 700n with the beat) surprise as me my model feels so much better even when we did some pitch pumps the tail just hold so solid if only i can put it into words lol.
this is the email i got from beast x
Hi,
the gyro doesn't know when the tail will start to turn. It has to measure the sensor data and wait until the tail starts to drift. So it always lags behind a little bit. Now when you give a very quick collective stick input or when collective changes from a very low to a very high amount in a very short time then the change will be so drastically that the gyro will have a lot work to do. By using RevoMix you can help the gyro as you simply add a small amount of rudder input against the rotor torque. This doesn't has to be very much and you cannot define exactly how much this has to be, as the amount of rudder stick input to be given is depending on a huge number of factors like wind speed, rotor, rpm, ... but it will help the gyro a lot as you tell it that it should get ready for work and you additionaly bridge the gap between occurence of torque and counteraction of gyro.
This also applies to a cyclic stick input as this also produces torque but on collective load changes are much stronger and more abrupt due to the larger pitch range. So usually you only need half (or even less) of the amount of revomix for cyclic than for collective and it is much harder to see a need for RevoMix. But on collective this can help very much and can give you a much better rocksolid tail. Anyway the need for it depends very much on the tail performance of the heli. If you have a lot of tail thrust available you should need RevoMix at all. But most people use to small tail blades, like to fly their heli with low headspeed, ... and then you can typically see that the tail shortly kicks to the right (nose to the left) with the rotor torque when they tuck in collective. So Revomix can help here out as raising gain won't and which usually is already maxed out.
