Hey guys,
I’ve got an interesting problem that I’ve been trying to solve for a while. During flights, I am getting the Potential Thrust Loss (2) error code.
See the link below for the kit I bought along with the componenets. The drone is well under the MTOW so I don’t believe the payload is the issue here. I have a 6S 11000mAh LiHV battery along with it. My failsafe for FS_BATT_LOW is set at 21.6 volts to RTL.
I have always received this potential thrust loss (2) error towards the last few minutes of the flight, typically the last quarter of the flight. The drone flies great for the first 3/4 of the flight, then starts to lose altitude a few times, and by the time you try to land it, it does not have enough power to land safely. Motor 2 does feel slightly hotter than the other motors after landing, but im not sure if it is enough to be worried about the motor itself. I also might be getting tricked because the ESC is inside the arm (see holybro x650 link), so it might be hard to tell if the motor is actually getting hot or not. There are no issues with the battery (I think) because in one test I did a few days ago, I flew 10 full flights, draining the battery to the failsafe each time. For the first 8 flights, the drone flew fine, no issues. The last 2 flights (which happened to be in the afternoon when it started to heat up outside) i started receiving the thrust loss error. From my personal observation, it seems to only happen on hotter days, especially when the wind starts to pick up. One thing to note is that the payload that I have has its own internal (small, 2200 mAh) battery that slightly sits to the side that motor 2 is on. I don’t think it is anything to be worried about though. The propellers are on correctly, all motor and prop bolts are tight, props are not damaged
I have attached a log from today when the potential thrust loss error occured, any help would be greatly appreciated.
Here is a link to a log where the potential thust loss occured as well as my components.
