Hi there - I am based in Brisbane Australia and bought a 3DR copter a few years ago. I almost have it working - Alt Hold/Loiter/Stab mode work most of the time. Other times it loses its self and hits the dirt. Does anyone in this forum live in Brisbane and would be willing to help me out on a paid basis? I may have an intermittent hardware fault with the acceleromters or the compass. Anyway if someone can help face to face I would really appreciate it. Thanks - I think its a great forum by the way!

Greg, you are corect that I am the person registered under the new UAS program. Because of that, I am required to follow the rules they setup. I also have a drivers license and am responsible to drive safely. There have been cases that someone else has interfered with a driver safely driving (say dropping a rock off of an overpass) and that has lead to the person interfering with safe operation of the car going to court.

I am required to put my FAA registration number on my aircraft to identify me for unsafe operation of my aircraft (RC). The FAA classified RCs as aircraft because it flies in airspace controlled by the FAA. They did not chose to registered kites, which also fly in the same airspace (generally below 400 feet). I understand that kites are tethered, and I have seen kites weighing more than a pound. I could tether my quad too, but they still require one to have an identifier they require, while the other doesn't doesn't.

During WWII, balloons were used in large cities with steel cables to bring down enemy aircraft. Kites could be used the same way (hypothetically), yet one is controlled by the FAA and one isn't.

I am unaware of any aircraft that has been damaged by a UAS anywhere. I have seen FAA testing of larger, heavier objects that have hit planes, yet not bright them down. Sure, it may cause damage, but commercial (and private aircraft) continue to operate safely. 

I fly my aircraft (RC) safely, but outside interference by another party could change that and it could hurt someone on the ground. The identifier on my quad would certainly lead to me if that happens, and I would be brought into Federal court to answer for it because of the actions of a third party. 

Of course, all of this I would have to present in court and the judge decides (or a jury). They will be the people that end up adjudicating this question. I do not anticipate ever having to do this myself, but it is possible I could be on a jury that decides that.

Craig I think you will find that you are registered not the aircraft. This is the conclusion I read in other places.

i had an interesting thought this morning and I was wondering if anyone had thought about this too. I have registered for the UAS registration. Not that I am especially pleased with it, I I have done work for the FAA in the past and have friends there today.

Since the FAA is requiring registration and have rules to follow, it would seem to me that should some stranger take offence at my flying and say shoot it out of the air, the FAA would be required to step in considering it is a registered aircraft and prosecute the person for shooting down a registered aircraft in Federal Court.

Since I have not found any reference to something like that, but know if I fly in an unapproved manner I would be proseccuted in a Federal Court myself. I have sent this question to the FAA, but have not yet had a response. I am pretty sure they will respond at some point, but considering that the FAA felt obligated to control this hobby, they also have responsibility to protect unsafe actions by a person that could lead to the destruction of a registered UAS. After all, having it fall from the sky and possibly injuring someone is no different than if an aircraft was shot at. The same may hold true if the signal controlling the UAS is interrupted, causing it to crash.

Overall, this would be a big burden on the FAA since these devices are so popular. Anyone want to speculate as to the answer of that question?

@DG:

Yes.  The FC is between the RX and the Quattro.

Comment by DG on October 31, 2015 at 9:25am

Does the FC Failsafe when set up override the motor  cut-off of a HobbyWing Quattro for lost tx signal? According to HW Quattro  manual, it will shut off the motors after 3 seconds IIRC after sensing no throttle.

@Cala,

I have sent the blog post OP a pm asking him to either remove the OP post review requirement or lock the discussion thread to further posts if that is his intent.
