Has anybody really pushed the RTH functions? One thing that isn't quite clear in the manual is the role the return to home power estimate plays in trigering the low batt failsafe. So does the low batt rth engage when your batt hits the low value you set or when the estimated power to get you back home is equal to what you have left? And has anybody tested the overrides? If I get a low bat warning and I head home myself, will the P3 constantly try to engage RTH even if I'm going in the right direction? I can see a case where you want to keep control and avoid the rig climbing to RTH altitude if it isn't needed.
