Hi guys firstly merrsy Christmas to everybody! I was trying to fly my phantom today and i struggled to get a GPS lock, but when i did i kept losing it. I just want to know, will the return to home function work if the phantom saves the home point at the beginning of the flight (rapid flashing green LED'S) but then loses GPS lock during flight? Will it remember the home point and be able to go to it even f it no longer has GPS? Or do you need a full GPS lock for that to work. Also, can having an uncalibrated compass affect the GPS? Thanks guys, have a good one!
