Lack of modulation control for cyclic rotation rates

Three-axis rotational speed is obtained by measuring the percentage of elevator, aileron, and tail stick displacement relative to center (rotation = 0) and using this percentage to determine the current model rotation speed read by the gyroscopes relative to the maximum rotation value set in the flight control unit via the configuration app.

In panel 5 of the configuration file you sent us, we see that the elevator stick reaches a maximum of 94%:

Therefore, you will only be able to achieve at most 94% of the maximum rotation speed that in ADVANCED, Setup tab, appears to be set in Setups 2 and 3 for the elevator at 360°/Sec (a full rotation of the model in a single second):

So 94% of 360°/Sec corresponds to 338°/Sec. maximum rotation speed.

It should be added, however, that the maximum rotation speed set in the flight controllers can never be achieved if the maximum rotation speed the model is capable of achieving is lower. The maximum rotational speed that the model is capable of achieving can obviously never be exceeded.

The maximum rotational speed of a model does not depend on the flight controllers but depends on the maximum aerodynamic performance of the model which in turn depends on the model's aerodynamic frictions (air penetration coefficient: CX), the weight/mass of the model, the center of gravity of the model, and mainly by the aerodynamic performance of the main rotor which in turn depends on the rotational speed of the main blades and the type of main blades used.

You did not send us as indicated here:

and also here:
https://www.msh-electronics.com/faq/#Q01

a Recorded Log of one of your flights to enable us to see when you command maximum elevator or aileron with what value of main rotor RPM you are flying.

Also, in the configuration file you sent us, the number of blades of your model and their length do not appear to be set in panel 10 of the Wizard (therefore as explained by the side instructions the PID gains of aileron and elevator do not appear to be set as also indicated by the orange background of panel 10):

From the configuration file you sent us we see that:
In the Governor panel (which turns out to be active and used to control RPM) as the RPM value for the first speed you have set only 1400 rpm which turns out to be a very low RPM value even for a 700 class model (we do not know the class of your model). At 1400 main rotor RPM any model will already have a great difficulty to lift but also a very low maximum rotational speed because of the little thrust the main blades have in the air.
As the RPM value for the third and highest speed you have set only 2000 rpm which is below the maximum performance that even any 700 class model can achieve (usually 2200 rpm).

If you are flying with a low main rotor RPM value, you can increase the maximum RPM values of the flight controller as much as you want (by switching from ACRO to 3D flight style, for example or in ADVANCE), but you would never reach the required rotation speed because the model cannot reach them aerodynamically because of the low main rotor RPM. Once the maximum rotational speed of the model has been reached, the model cannot increase its rotational speed any further.

The most obvious example is when you ask the model to rotate while it is resting and stationary on the workbench.
The swashplate already reaches its maximum tilt in an attempt to rotate the model even though the sticks are only halfway up, but more than the maximum swashplate command the controller is unable to give even if the model's rotational speed is zero because it is stationary on the workbench.

Notes:
In panel 1 of your configuration file we see that you have not selected any servos for the cyclic and tail or even the type of blades used. Could you please tell us what brand and model of servos and blades you use so we can consider adding them to our lists?
Thank you!

Thanks for the reply. I have set the blades multiple times, but it seems to clear them when I go into the Ethos integration for some reason. 

To clarify, I am getting the desired rotation speed as the model is absolutely more than capable, it is just that it reaches the maximum rotation rate way too soon in comparison with the cyclic stick movement. Basically, at only moving my cyclic stick through HALF of its travel, then I'm getting FULL rotation speed already from the model. Again, this is the effect in flight, not on the bench as I understand that concept. 

I deleted my logs accidentally, so I will be doing a flight today hopefully and send you the log file. I will try to select the blades again on the computer and not enter the integration at the field just to be sure. 

I am using a Goblin 700 black thunder with 716mm blades. Flies fine at 1400 and 2000rpms. I am using Theta C1 and T1 full size servos in this model.  

From what you write it seems that the rotational speed you want, which corresponds to the maximum rotational speed the model can achieve, is lower than the maximum rotational speed set in the flight controller.
So you could halve in ADVANCED, Setup tab, Cyclic section the two values of maximum rotational speeds to get a more linear control.

To measure the actual maximum rotation speed, you need to ask a friend to start a stopwatch when you start an uninterrupted sequence of model flips for half a minute and ask him to count how many rotations you do in 30 seconds.
By dividing the number of flips done by 30 seconds and multiplying the result by 360 you get the speed of rotation per second.
The same values (number of flips and elapsed time) can be obtained and measured in a Flight Log using the times the model reads 1g Earth gravity (steps for horizontal model attitude).
Or by measuring the rotational velocity value read by the gyroscope relative to the axis in which you spin the model.
