Thanks for the quick replies, u are obviously a valued member to this community!Accuracy totally depends on VPS but in an outdoor scenario you will never get the tolerance anywhere near what you are expecting, and Tello does not land on its own. I am happy if Tello comes back to within 5m. But on a long range trip its OK if Tello returns into the right direction and comes close enough for me to take over using LOS.
If you have expectations for landing on a pad AFAIK only DJI drones mix their GOS with downfacing camera to achieve "precision landing". But: take away the landing pad so their visual reference is gone and they will land within a few meters just like any GPS drone.
Volatello , I've reduced my phone's (galaxy J1Ace Android 5.1.1) fonts. but still don't see the scan button in the TelloFPV controller menu- see picyou have to go to settings - controller and press the scan button. If you don't see a scan button you have enlarged system fonts so its pushed too far down.
Pls report back if this works.Volatello, The pic above was with small font. going to tiny, I was just able to see a thin grey lines at the bottom of the menu. This is the top of the scan button! So got it working, seems the J1ace is a bit too small screened. Thanks for you help! Have not tried it with screen sticks.
I think it all depends on the wind. I've flown many times taking pictures at 30 meters with mild wind without problems, it made me very proud of tello and this app! But at 30 meters you can get some sudden strong gusts of wind and vps becomes more susceptible to fail at high altitudes. I think you have nothing to lose by downloading the app UAV forecast or something like that. It gives you wind velocity for the height you are planning to fly. You know tello can get about 28KM/h in sport mode so you should try to avoid winds stronger than 18km/h or even less, at 30 meters, just to make sure you have some power to return.So what is a safe maximum flying height with your app
