No Video SirWell I have had moments landing that where not perfect was that using RTH I now know to not entirely rely on the auto feature of RTH and will cancel and do it manually if need be. Did you create a video of the flight ? Was it a night flight ? post it if you can
it was a night test flight with a new controller.
Mostly it was to take off and land in that less than ideal environment.
The Tello video feed is marginal to non exhistant when metal is so close....
with no directional indicator you are lost at a few feet with the Tello.
I really sympathize with those learning to fly in a large large city like Bangcock.
There are recent great step by step procedures for compass directional indicator syncing here.....
That said I had a hard time in a rural environment getting the hang of the positional indicator......my steel toed work boots can throw the indicator off....I try not to wear them but if I do the turn on process is get on knees with boots as far away from bird as possible.....then lean over to double press the Spark power and crawl back before it fully comes on.
Even slightly buried pieces of metal can make you wonder what is wrong.
Keep Learning guys
And if given the opportunity get away from all that concrete filled rebar and so many wifi and Bluetooth radio waves......The Spark is a remarkable craft.....it’s worth a day trip to take it for a little fly time in a rural area.
