Hi all. Fairly new to flying drones but learning fast.. my q500 4k over the past few days has gone a bit crazy.. I have very little control of it in smart mode.. no backwards movement at all and not going where it should be according to where I push the control stick to.. angle mode hovering is just out of control.. It will drop suddenly up to 1m to 1.5m and has a crazy drift. Angle mode flying is very messy with a lot of jerking wobbling the whole machine is very unstable. I calibrated accelerometer and compass and also calibrated St 10+ but no change. I also noticed that my batteries are draining so fast.. about 10 - 12 mins with absolute zero wind. 12 satellite on each. The drone is practically brand new with about 6 hours of flight in total. Any help or advice would be great.. Thank you.
