Thanks. Another quotation, when i fly it, sometimes it keeps on drifting toward a direction. I understand the VPS causing it but anything to correct it?
Also, grainy video feed and recordings. Any way to counter that as well?
My drone has been very stable as long as VPS is working, in other words when it's not very dark. The warning message about low light that comes up can be safely ignored as long as it doesn't get any darker, in my experience the VPS will only stop working completely when it's so dark that you can barely see anything on the video feed, but can start drifting a little on and off right before it gets to that point. Also in medium heavy wind it can start drifting as it struggles to stay in the same place, so I have to be careful not to fly close to any objects when that happens.
So if it drifts, low light and wind are the two possible culprits.
Low light is the Tello's greatest enemy, even greater than wind, which it actually handles surprisingly well and it has still been able to fly (with obvious great effort) when it was rather windy outside, the battery was drained twice as quickly as a result though. If the camera did a better job in low light, and the framedrops (even with BT off and within 10m of the drone they still happen) were fixed, it would be a near perfect little drone. Of course I don't expect it to be perfect for the price, but would gladly have paid $50 more just to have a better camera and wifi transmitter in it.
In short, there's not much you can do about the low light performance, though I suppose you could get some kind of LED keychain light and stick it onto the Tello which would help alleviate the issue a little at least when near enough to an object/surface to illuminate it.
