Okay, I'll try some of my GemFan Tri-blades and see how they work first. I was pleasantly surprised to see it flashed with BetaFlight. It also bound right up to my Taranis. Setup was a peice of cake. Are you running a GoPro? If so, how are you mounting it? This looks like a hard bird to mount it to. Have you tweaked your PID's at all?
