I just built a PhantomX with 18A servos and some the tibia servos are not being found while running the build check. I suspect not enough voltage is getting to them. Initially, it was #5, 6, 11 and 18 not found. Then I was getting the low voltage failure so I check every servo ID and range with Dynamanager and double checked all the wiring. Then I was getting #5 and 11 not found then 5 and 12 not found with 11 working. I have tried both 12v power adapter and battery and checked the voltage on the power adapter and it is good. Tomorrow, I will try another 12 volt power supply that will give more amps but if that works, it still doesn't help me run off the battery. Much thanks to anyone who has ideas on how to fix.
