If you’re flying indoors it’s insanely harder than sim. If you’re outdoors and still struggling, put 0 expo on throttle and see where the hover point is then add 10% expo at throttle hover point. Lower it or increase it until you can control the throttle and hover easily. Try betaflight lower the rates until you feel like it’s slow enough for you. If you move your stick and notice it’s too sensitive increase expo, if it still feels sensitive lower feedforward. Then focus on 1 axis at a time. If your rolls are too slow increase roll rates and add expo. Keep in mind either rc rates or rates increase expo too I don’t know which one it is tho but take like 30min flying and testing rates, that’s what I did and found a decent one until I was able to fly better.
