..I am still fairly new at the Phantom hobby. I admit I got a lot of my "training" from watching YouTube. I was under the impression that you were supposed to do the "dance" every time before flight, but always for sure after changing location. Now I read that that is just asking for a problem. What is the prevailing wisdom? Also, maybe a dumb question, but here goes....Assuming the craft is in GPS lock and I then switch to IOC (course lock) is it still using the satellite,s for stable flight and finding home. What if I am using "return to home" function? (sw2 down) The reason I ask is that my last crash was when I was using return to home in NAZA mode. As the craft approached within maybe 20 ft out and 10 ft high it suddenly did a "falling leaf" impression and damaged my gimble among other things. I have been afraid to use that mode since then, but have had no more problems while flying in GPS mode.
