"Hello, At the end, we connected the all 4 esc on another FC and confirmed the problem comes from the pixhawk. I guess we will buy another FC. I filed a support ticket to 3dr without any answer, this is sad. Crossing message on the the forum I find…"

"Hello we have a similar problem, can move a motor with their respective esc from a PWM input, but when I connect the 4 motors to pixhawk, for some strange reason one engine does not work, was a esc yesterday, today was another esc who does not work,…"

"Hey! It wasn't the PWM throttle value being too low :( I did get all the ESC to init and motors to start in stabilize mode (was in althold before as a default mode) but 1 of them didn't start right with the others, it took him like 10sec…"

"I'm off the office for a few days, so I can't test for now. But i'm pretty confident you put me on a track with the low PWM throttle. Out of pure memory, I think my lower throttle pwm was around 975. I found it strange while setting…"

"According to the Air 40A ESC manual, those other two aren't receiving a output signal from the throttle channel from the receiver. So it might actually be a ESC calibration issue. I don't have much experience with Futaba products so I…"

"Sorry, misread the 1st part: So each ESC continuously beeps at 1 second intervals until you arm the safety switch and then only two will arm and the others continue to beep. <= Yes.  2 ESC just continu to bip like I didn't activate the…"

"You got something here. It can pretty much be that considering I've never used the Pixhawk with this RX/TX. The throttle min can be too low. I'll check that and let you know. Thank you very much! Raph"

"hmmm...thats pretty interesting. Maybe you could flash your pixhawk with the latest stable version of arducopter and start from scratch. I would also check the continuity of each of your solder joints. Also check your RC_3 MIN and MAX PWM values…"

"Thank you for your reply Chris. I also tried to use the Pixhawk all-at-once calibration, but only 2 out of the 4 esc starts the calibration process. It's pretty much following the same pattern as when I use the switch to unlock the quad, it…"

"They should work fine together. I use the Tmotor Air 40A ESC with Tmotor 580kv motors and a Pixhawk FC. I used the all-at-once ESC calibration method listed on the Ardupilot wiki page. http://copter.ardupilot.com/wiki/initial-setup/esc-motor/ I…"

"Does anybody have any idea on this topic? Is my pixhawk damaged or those ESC simply don't work with it?"
