Warbling Tone

Mark11 · Jan 4, 2025

I have a V3 RTK with the latest updates to android, system and firmware. The start up tone is normal, then a few seconds after start up the aircraft makes a intermittent kind of warbling tone and I’m not sure why. There are no warnings on the controller and the aircraft flies normally in all respects. The intermittent beeping seems like its a new feature, can anyone tell my why this is happening or what the sound signifies if anything?

The warbling tone is produced by the pan axis gimbal motor - which also gets quite warm while making with warbling sound. There is some sort of mild instability in the pan axis which is produced by the motor over correcting for some issue _ i dont’ know if the problem is hardware ( gimbal ) or software . At this point. I have also had issues with firmware /software updates in that the controller main app updates, supposedly the aricraft firmware is updated to 1.3.4 but firmware components like image transmission are not the latest versions for some reason. I am puzzled.

Problem Solved!. After a bit of poking around to find the source of the warbling tone, I found that the pan motor in the gimbal was subtly oscillating and marking the noise. I looked through the Autel software versions table at the various firmware my aircaft should have and found that the Gimbal was on 0.0.20 and should have been on 0.0.26 and the image transmission versions were incorrect on both the cpntroller and aircraft. I messages tech support and they suggested a reload of Firmware update via micro SD and sent the official version in their reply. I updated the drone as instructed and after 2 reboots the Gimbal and image transmission firmware were correct and the gimbal problem was solved. Autel tech support was helpful and responsive in helping me correct this problem and now back to flying.
