Got the original J-Drones ESC's an a strange phenomena
when i plug in the LiPO i get a beep beep beep beep ( fast around 3 beeps per second ) from my motors.
I think this means " under Voltage ". My LiPO is fully charged and after a few try's sometimes the beep go away and i can fly....
Got no Ottopilot attached and disabled all Battery monitoring settings in the setup.
any advice is highly appreciated
Does it happen always or only when flying outside? Some ESCs are suspectible to cold - if you let them be for a while they warm a little, holding them in hand helps. This signal is usually that there is incorrect signal (too low/high pwm). Try recalibrating your radio with a lower or higher throttle trim (and reset it after calibration), or calibrate it when cold.
thank's a lot !
did just the RC Calibration again and it works fine.
The temperature issue i had as well when we had -20C
