However in OpenPilot 15.02 they added support for OneShot125, and since I upgraded to OpenPilot 15.02 and enabled that option I'm sometimes having trouble getting all motors to start correctly. I posted about this on the OpenPilot forum and someone else confirmed the issue so I thought I'd open an issue for this on GitHub. See OpenPilot thread here: https://forums.openpilot.org/topic/55149-oneshot125-support/?p=412578\r\n\r\nShort description of setup:\r\n- CC3D running OpenPilot 15.02\r\n- Afro 12A ESC's, BLHeli 13.1 default settings. Ground and signal connected on all ESC's. One connected with 5v to power FC/RX. Damping not enabled yet (unsure if it works with my motors..)\r\n- Multistar Elite 2300kv motors\r\n\r\nIssue description:\r\nWhen I apply power to my quad, the quad plays it's initial startup beeps (a remote controlled beeper + battery beeper + ESC's etc). Sometimes (I'd say 2 out of 10 attempts) when this is done one or more ESC's make an additional beeping sequence. When I arm and then apply some throttle, one or more motor's then won't start at all. I've already tried recalibrating the ESC's and raising the minimum starting power in GCS. Sometimes when I disarm and wait for a while, the ESC's beep another time and usually I can then start additional or all motors. When all motors start correctly there is no issue flying and OneShot125 seems to work.\r\n\r\nSteps to reproduce:\r\nI've been unable to reliably reproduce this, it's always different combination of motors that show an issue. Ea. sometimes front left, sometimes all on the right, sometimes only rear.. It will work correctly 8 out of 10 times. I think this could perhaps be an issue with the protocol detection at ESC startup in combination with heat/timing unreliability? It seems to occur more often after a couple of flights.\r\n\r\nThanks for your time!"}}
