I'm having a heck of a time getting my ESCs calibrated & motors armed… getting a slow beep every second from 2 of my 6 ESC/motors. I'm building a 3DR Hex kit with 20 amp ESC & 880kv motors.
Here's what I did:
○ I Never got confirmation/arming beep from ESCs
○ I Get a constant beep every second with APM blinking A/red LED & solid C/blue
○ Are the ESCs successfully calibrated?
• Wiki says… ' If the ESCs are not beeping or are beeping slowly but the motors still wont arm, try setting the transmitter trim 7 or 8 down from center. An offset below zero is needed to permit arming.' I recalibrated the Radio in MP.
See attached scn prnt
I set the JR transmitter XG8 Sub Trim function from 0 to 'Low 51' (to address the wiki 'offset below zero needed')
Result is I get same slow (1 per second) ESC beep & can't arm 2 of my 6 motors
I have done this 8 times. I'm stuck & need some suggestions.
Any ideas please?
I discovered the cause for my inability to arm motors was due to my stick movements needing to be reversed. I discovered this when looking carefully at the desired PWM high/low values when doing the MP > Calibration > Radio step. So I now have 5 of 6 motors arming OK.
The 6th ESC can't seem to be calibrated. So I'm waiting for a replacement ESC from 3DR.
My only remaining issue is I can't stop the motors from rotating; even when the stick is all the way down. See my other post.
That's great news about getting into the air without having to fiddle with the PIDs.
