I am having a lot of trouble. I don't know what else to do. I just updated ST16 and the H to the most recent software, I went along with the tutorial video put out by Yuneec to make sure I did it right. I am still getting the rapid blue flash and beeps. I tried to fly a few days ago and couldn't even take off, the blue flashes and beeps wouldn't stop. I calibrated 3 times. Just updated, haven't gotten out of the house to calibrate away from wires and such. Now I'm getting a message on the ST16 saying "Obstacle avoidance failed" and I'm not even off the ground. I'm on hold with customer support, estimated wait time is an hour. Any ideas? Thanks!
