lol, make sure you set a fail-safe, even better,use tower beta and set the kill switch option.,i lost the drone first flight, it flew of and wouldn't come back !! scary, very...
once i had lost sight i turned the radio off, i think at this point it just dropped... luckily it didn't hit anybody,i found it about 1/4 of a mile away, close to the last known gps location.
luckily the WiFi stayed connect untill it dropped.
also lucky, it was still powered up, and the wifi reconnected when i got close.
lots of luck here, be careful guys
