Maybe someone can explain me why this is happening. I have a JR X9503, bound to Mini Vbar with two DSMX sats. This setup is for my Gaui X3, KST DS215's on cyclic & DS515 tail, castle external BEC 10a & castle lite 50 ESC. The problem is whenever I applied power for the first time to the system with my radio being on ready to fly, one of the servo won't have power after the Vbar initialized, usually its either the aileron or tail servo. But after I unplug it from the battery and cycle the power then everything goes well, it takes about one to two power up cycle before all servos cooperates to one another. Can someone pls tell me why it's doing it, appreciate it.
