I've been flying Phantom1 for a couple of years, and getting a P3A in next few weeks, so have been reading up but cannot find anything on this. I am planning to do some video off a cliff, so will take off from top of cliff, then fly along cliff face (~10M below take off position), and hoped to use waypoints to recreate a path around some rock stacks to the beach. I have read waypoints need minimum 10M/32ft height, so can this restriction be removed in settings for me to make this flight? Also, any issues with flying below home position, with Phantom1s, I actually set home position 15M in the air (to ensure clearing cliff if signal loss), and flying below 'home altitude' works perfectly, but obviously its a lot more basic than the P3 and don't want to find out the hard way the motors will cut out when flying below ground level. Thanks.
