Solved
I was able to get the beeping to stop by setting my RC3_MIN to below 1140. I currently have it set at 1130 and have since adjusted my transmitter to make min throttle around 1100 and max around 1800 using the THR C/V.
I am still looking into why this works and I plan to make a video or blog documenting these solutions, but if you end up with the same problem with DJI E300 ESCs, know that this is what worked for me.
Good Luck and feel free to message me for questions!

Hi All!
I'm excited about my new drone but lately I haven't been able to fly. This started happening after I replaced my Turnigy 9x 8ch receiver. When I power on my craft then engage the safety my ESCs all start beeping. See this video:
The beeping in question starts at 0:35 if you want to skip to it.
I can't find anyone else with this issue. I know the ESC beeping might be that the ESCs are receiving too high signal but I don't know why.
The issue seems to be intermittent. We were flying on Saturday and did 2 good flights, tried to fly twice and we were stopped by the beeping, then after some power cycling we did one weird flight where the throttle wasn't right.
My Craft:
- DJI F450 ARF (450 frame, E300 ESCs, DJI 920kv motors, 9x4 props)
- Pixhawk with Arducopter 3 + UBlox 3D GPS / Compass
- 3DR Radio Telemetry Kit
- 3DR PPM Encoder
- Turnigy 9x Transmitter / Turnigy 8 Channel receiver
Previously posted the topic here but corrected the throttle output issue:
Edit: A log is attached which I think is from during the video but I'm not sure. It also says the flight happened on March 19th but the flight was on March 18th, 6:43pm PST.
Updates March 27
What I tried that didn't work:
- Changing RX
- Completely disassembling and reassembling drone
- Inspecting all wires, solder, etc (no damage)
- Changing motor positions
- Reinstalling APM Firmware
I finally tried QGroundControl and installed the firmware available on that platform and the beeping went away. It seems this is an issue with the PixHawk APM Firmware. I haven't had a chance to try and compare them yet but I'll see if I can try older APM firmware version or tweak settings to get at what the root cause is.
If anyone knows how to debug the signal sent to ESCs that would be greatly appreciated.

Do an auto ESC recalibration. That should clear it up...
I don't think DJI E300 ESCs can be calibrated or I can't find any way to calibrate them. Do you know if there's a work around there? I have tried the instructions you link to before but I will try again right now.

You might be right. I've never tried those ESCs... All the regular ones work fine
[SOLVED]
I was able to get the beeping to stop by setting my RC3_MIN to below 1140. I currently have it set at 1130 and have since adjusted my transmitter to make min throttle around 1100 and max around 1800 using the THR C/V. Still not sure why RC MIN seems to control this even when the transmitter is powered off but it works! More details above for anyone who finds this in the future.
Hi, I have the same problem.. Where do u set? RC3_MIN in apm planner 2.0?
I suppose it was in CONFIG/TUNING -> STANDARD PARAMS but I doesn't found it.. Please help :) best regards
Hi Alessandro!
I'm not setup to try this at the moment, but I think you need to enable File > "Advanced Mode" . Then you should see the parameters under "Config and Tune" and you can search by parameter name.
Another note to add here, I ended up replacing a cheap turnigy 9x with my new FrSky Taranis and all my problems were solved. My transmitter was very inconsistent with the throttle output so sometimes it would arm and sometimes it would just panic. Investing in a higher quality transmitter helped in my case and if you're getting weird errors it may be some inconsistent behavior in the system.
Best of luck, hope you're up in the air!
I think this issue may be with the APM PixHawk firmware. I tried QGroundControl and installed the firmware there and the beeping went away immediately, no hardware changes. It flys great but I prefer the APM firmware so I'm attempting to investigate what's different. Still on QGroundControl for the time being.
I was able to get the ESCs to make the calibration tones shown in the video but after they seem to calibrate the beeping still persists.
