Took my H out for 3 flights today. Without a compass calibration it stayed perfectly still a 20 ft. Brought it back down and it landed perfect. Kept it in pilot mode with sonar off for all 3 flights. Very stable platform. Took it up to 400 ft and out to 1540 ft. Lost Telemetry data around 1540 ft. I did not play with any camera or automated modes yet. So far I feel it beats the Q5004k in every aspect I tested other than sneaking up on wild turkeys. With the Q I can fly as fast as it will go over a flock and they don't notice it. At full speed with the H the flock dispersed quickly. So far there is no rattling from inside my ST16. So far no issues other than the telemetry dropping out.
