@HenkB Which CopterX do you have? I need to know how the servos are sitting and which way the arms come off them. What I want to know is which direction does each servo are turn to move the swash up?
As an example, here is a picture of a 450, the two servos shown, which should be cyc1 (on the left) and cyc2 (on the right) both rotate CCW to move the swash up, and the cyc3 (on the opposite side) will rotate CW to move it up. Therefore, cyc1 & 2 should both move in the same direction when the throttle stick is moved. On first glance, yours move correctly, however if you look at the pitch screen you have a weight of -50 on cyc2. Set that back to 50.
When you do that and go to your outputs screen you will notice that cyc1&2 are not moving in the same direction, cyc1 is off to the right and cyc2 is off to the left. So, you need to then reverse output on either cyc2 to get it moving the same as 1, or swap both 1 and 3. After doing that, your servos should then be good to go and all that should be left is to set proper directions for ailerons and elevators.
If you need to change the direction of ailerons/elevator I suggest you go to appropriate mix page and change the weight there from a positve to a negative as shown below.
Lastly, I see that you are using the "-throttle" for pitch and throttle, but you don't have that mix defined anywhere that I can see. Personally, to avoid extra "noise" I would set your source back to the regular throttle and go through the above setup changes where throttle up means more pitch and more throttle, and then after you get everything working properly, add in the negative throttle thing.
