In fact it's not really a bug, but a new function that has been added and that can embarrass + than anything else in certain situations. In the last firmware they have added a function that limits the inclination that can take the drone according to its altitude. So if you fly in a corner where you stay at low altitude, your drone can not take its maximum inclination, so if there's a little gust of wind, as the
tello is not going to bow to the max, it will not will not have enough "power" to fight the wind and you will have the impression that it does not answer any more and even that it is locked in the wind without reacting. It is enough to go up to more than 2 meters I feel when it happens to unlock the max inclination and fight the wind, I just test and it works effectively. But for that it must have room, if you are in town in your garden with not much room, this new function makes your
tello unusable at home as soon as you have a wind chouille since you can not reach a strong inclination at low altitude. That's the explanation I found, and it looks like that. I hope it will improve the thing because whoever just wants to fly in his little garden can not really...
I spent my first battery at low altitude and I did not stop finding myself with the "pbm", then I spent my second battery between 3 and 20 meters without ever having the pbm. At one point I intentionally hovered 50 cm above the ground and the impossible to get a maximum inclination with my drone drifting, I put a gas to go up to 2 meters and max inclination available.
Too bad this kind of function on a small drone sensé stolen rather ds small places, it should be deactivated. I just dumped two batteries still there and just to land where you want when there's wind is more possible, more boring than anything else ? by the altitude modification super convenient, and super stable at 30 meters even with wind, awesome.
