The one fun thing about sound with the Syma was that it made crash videos more dramatic. And what kind of iPad are you using? It's my understanding that a lot of them don't have GPS built in, which would make follow me mode impossible.
Yes, i have set The RTH attitude to 30 m
Yes i also thought about setting RTH to a higher altitude, i dont know, but i get kinda nervous when the drone is so High up [emoji1][emoji1][emoji851][emoji851]
Unless it is very windy, higher has the advantage of having less interference from ground objects and better GPS reception. And less things to run into.
And also, i a cannot enable The IOC in The app? Its "grayed out"
IOC remains grayed-out on the ground. You have to be airborne at least 10' high for it to become available.
