Thanks Silent.
Another Informations:
1) I tried all other 3P Switches, the radio performed abnomally all the time.
2) If I disable P1 & P3 in arco condition (In other words, all D/R NA with P1 & P3 in arco condition. You can check POST #5 comments), the issues DISAPPEAR. (Of course the D/R logic is not changed: P1 all small, P2 ailerion small only, P3 all large )
So I think there may be some logic or circuit issue with my radio. However, I still believe it is not single but may be a common issue with some 14mzs due to circuit or driver SW bug.
Thanks any way, I will send it to Futaba service center.
Must be a language barrier. What you describe is 100% consistent with bad pots. There is no "logic fault" or "circuit issue". Let us know what the service center says after you send it in.
