New mavic pro pilot and had a quick question maybe some of you experienced. was flying about 5 ft high at about 20 mph for about 30 yrds. when i let of the throttle the mavic dropped in altitude causing it to bottom out into the snow. it was soft snow but the bottom of the drone got somewhat wet. I dried it off and seems to fly fine, I will just have to be more cautious when flying fast and low. Does this happen to anyone else. FYI I have calibrated the imu, compass, and vps using dji assistant2. it only drops altitude when i am going forward fast and let off the throttle suddenly. isit normal to expect this behavior. thanks for any help, fly safe
