Motor#1 ESC wont arm.

[andrebandre]

I am experiencing a little bit of a problem with motor#1 ESC in a quad configuration multirotor.
It works alright if i connect it directly to the Rx throttle channel.
I checked the WK-M input M1 by connecting the motor#3 (same prop rotation)to it and it works.
I connected motor#1 to the M3 input and same result, no arming of the ESC.
I then tried motor#1 on M2 and M4 just for good measure.
No arming.
Like i said if i connect it directly to the Rx it works just fine.So do all the others.
I did program and throttle travel calibrate all 4 ESC's prior to installing to the frame.
I can't think of what might cause the behavior.

HI andrebrandre,

i dont quite understand whats going on. One of your motors attached to a specific ESCs and connected to M1 doesnt work ? Different combinations work ? Or is it defiantly M1 that has an issue ?

Hi Boris,

Thank you having a look.

"One of your motors attached to a specific ESCs and connected to M1 doesnt work ?"
Yes.

After some more fiddling i can only point to the ESC as just uncooperative.
Every other ESC works in any of the MC motor inputs, the ESC in question doesn't work in any of them, but works connected directly to the Rx.
So i will wait till the Herkules is available and give that one a try.
Never been comfortable with the idea of using cheap ESC's. Not consistent nor reliable enough.
