3pks.2.4G 3ch問題

想問下3pks 3ch要點set先用到架?
我試過扭控上面果個旋扭都無反應既
係唔係要set過先用得?

Yes, first of all, go to menu 23 - DIAL.  Then asign a switch for channel 3, 3/PS.  
You set the DT3 for channel 3, 3/PS(3 position).
The above example is for trailer changing shift.  When kick the right hand side trim, the servo with move one step up or, one step back to central.  Hope you understand la!!
