Ive been having some stability issues when I fly my inspire 2. When I take off there is a lot of drifting that happens even in perfect conditions. It constantly struggles to connect to more that 5-6 satellites and drifts 4-5 feet up and down when im flying and its killing me. Almost every shot I get with something in the foreground is unusable because of the drifting. Ive calibrated compass, imu, and still drifting badly. Any advice on improving this issue?
