Thank you for the details.
If the settings are same in your radio for both helicopters, then probably your first assumption is very probable.
The AIL pin could be loosing connection which is not good if it is used for SBUS2. But still we are not sure.
If changing the units is possible, it would be definitive proof.
If not, we can try to find other way together.
In any way if you can send the unit to us, we will fix the problem in a few minutes as we approximately know where the problem could be.
It looks like you are from Korea, I think that we could manage express shipping from you to allow returning the unit in a few days back to you.
Thank you for your support. I swapped the units and , what can I say, both seem to work okay now.
I have to test more but it seems okay. So I think you are right about HW and SW. I don't think I can spend more time to find the root.
Changes are made after swapping
1) reduce throttle frequency to 60 Hz
2) I set channel 1~8 the same and off 9/10 channel in spirit
3) I used double side tape to fix the connectors
4) I found that CC sometimes doesn't initialize well on lower side (Futaba reversed) with default frequency range.
So I changed 20us lower and higher for both end while throttle settings (
5) I found if I move WIFI module close to servo signal wire it buzz and servos moves tiny bits.
I will report if I find anything.
