After some use of the BT-300’s, I believe they are the very best solution when your are recording scenes while flying in FPV mode. I have found, however, I usually fly many planned short takes which I set-up with various Intelligent Flight Mode patterns. This creates smooth, well planned footage and enables a simpler set-up. So, if you style is likely to be a more spontaneous FPV mode, I’d strongly recommend the BT-300’s. Otherwise, keep it simple with flight modes and a smart phone.
