Ok so I did some testing today. I flew the aircraft in the same conditions and manner in which it overheated yesterday. I did a 16 minute hyperlapse shot at a stand-still hover. The shot completed without the drone overheating. I actually ran out of battery before the drone overheated, which is interesting. However, the temps got up pretty high- I saw 67.5C on the controller, and the flight log shows 154.2F. I also took a laser temperature measurement of the battery after landing and it showed 151F. Interesting that the temp is hotter than yesterday’s (147F), and it still didn’t overheat. However, as soon as I landed and the airflow stopped, the aircraft turned off due to overheating. So it was probably right on the verge the entire time. But I think it’s probably safe to say that as long as we monitor the battery temp and keep it below 60C, we shouldn’t have any overheating.
Also of note: I thought that maybe more maneuvering would help it cool better. It appears that is not the case. After letting the temp rise to 62C, I did a ton of flying around and maneuvering. The temps just kept going higher.
Thank you for all of those details.
What really needs to happen, is for DJI to put an overheat gauge on the in-flight screen that you can monitor without digging into the menu, or give a three or four minute warning that tells you if you do not perform a controlled landing, a forced landing will take place because overheating is about to occur.
I don’t think that’s asking for too much, and it will save a lot of aircraft, and at the end of the day, DJI money. |
