Possible bug with OneShot ESC

ArduCopter Copter 3.5
1

Hi,
My setup:
Motors ESC and propellers all KDE direct.
Flashed with the latest firmware.
Pixhawk 2.1 running Arducopter 3.5.1

Separate CC BEC for the servo rail.

The ESC calibration using OneShot does not work, it never finishes the process.
I used regular PWM to calibrate the ESCs and changed the MOT_PWM_TYPE to OneShot before the flight.

You can see in the video that the Quad twitches and is uncontrollable. The PIDs used are the same ones that where tuned on the same configuration (that flew pretty good) except the ESCs which where hobbywing Xrotor 50A.

That esc support oneshot?

pixhawn doesn’t support oneshot calibration, I asked few days ago.

4

The KDE supports it.

@piotrm Do you know if it supports oneshot operation?

Yes, you can fly onshot or oneshot125
Calibration possible in two ways, calibrate as regular esc or use BLHeliTool and approximate ranges set in MP.
