I followed the manual for the Spirit on setup. I set the cyclic ring to the max I can get on my 380-420 helis without binding. I set geometry at 6*. All the while keeping it in the ranges stated in the software pop ups. I balance the heli as best as I can. I go out and do several tweak flights to get the feel I want and the issue is always there. It is a very minor issue now but always there.
I understand I`m the only one seeing the issue. It is not a deal breaker. I just adjust for it in flying.
Separating the tuning of the cyclics
You can try decreasing Geometry 6° by 20-30 and/or to increase Cyclic Ring to achieve 12°. Or you can decrease it to verify the opposite (lets say to 8°) - if you will encounter even worse behavior, then by increasing it can be all fixed.
Stick Deadband is fine around 5 - 15 for the most pilots. But with very low values (5 and less) some problems could arise. So it is better to stay above.

I can not reach 12 on cyclic ring without serious binding. Plus was it not stated to stay below 11 degree to prevent boom strike with rescue?
If I decrease geometry by that amount then I`m on the really low side of the range stated in pop ups in software.
I keep stick deadband at 10.

Here is excerpt from the manual:
The idea is just to find what is real reason for the issue. So it is good to just try. 11° is more than enough for the most models, but still there can be combinations that require very high angles. The higher the collective pitch angle, the higher angle is needed for Cyclic.
It always depends on the model, head speed, blades and servos what angle you can set. Basically for all smaller models nearly any angle is safe with a decent head speed.The settings here should be done very carefully to avoid damage to the model or it's associated electronics. Never exceed recommended angles by manufacturer of the model, otherwise a boomstrike can occur.
First, set your desired Collective range, for example, +/-12°. We recommend using a -100% to 100% linear collective pitch curve in the transmitter. Now it is time to set the Aileron/Elevator maximum cyclic pitch range.
Try to set the largest possible deflection. Generally the Cyclic pitch angles (range) should be equal or lower than Collective pitch. This parameter does not directly affect the speed of rotation, but if it is too low, the model may not have consistent pitch and roll rates. The setting should be done with 0° collective pitch. Then carefully move with sticks in all directions to ensure that mechanical binding does not occur. This should also be done for the maximum and minimum Collective pitch.
If you increase the collective pitch range, this parameter must then be checked and in some cases adjusted to ensure no binding occurs at your new maximum and minimum pitch ranges. If the selected cyclic ring range is insufficient, it is possible that pitch-up can happen during fast forward flight (even if the pitch-up compensation is at its maximum value). This is because the model will not be able to add sufficient corrections with the configured range.
