Recently, I had a problem with my T-H making a continuous sound without touching any control. The sound is like what we hear when we move the right hand joy stick out of neutral. It will stay on until we let go of the stick. But in this case, I hadn't touched the stick and all of a sudden it began to make the sound.
With both the St 16 & the T-H powered up, I selected the System Settings and tapped OK. The sound stopped because I had gone out of the Flight Mode Screen. I then tapped the Hardware Monitor feature and saw the display of all the control levers and switches. All were ok, except the J1 & J3 indications. J1 showed 100% on, and J3 showed just the opposite. I've added a screenshot so you can see what I saw. Nothing I could do would make the settings go back to zero.
Consequently, I decided to start the motors, but when I did, the T-H tried to FLY! Fortunately, it went away from me, flew horizontally across the room and hit our TV cabinet with glass doors. The door wasn't damaged, but two of the props were destroyed! I called Yuneec the next day and we went thru a series of tests and calibrations and that corrected the J1 & J3 indications and the sound stopped, but we could not get the camera to bind to the T-H. So I sent it in for repair. I now have it back home and flew it yesterday without any other problems. And the landing gear now operates as well. That was another problem a few weeks ago.
So my point is, before you fly, check the Hardware Monitor to make sure all is in neutral and moves in the correct direction when moving all the controls. I hope this is a rare event, but you never know when it's going to bite you! Fly safe!
