It's my understanding only the 7010 and above will support the proper failsafe for the Naza to function properly. And to engage that failsafe the operator must power up the rx with the bind plug installed and then REMOVE the bind plug, and then power up the TX in bind mode.

This aircraft is built from consumer grade components and it is designed to be flown by a human being, start to finish. Understand too, there are many component and system variables such as connector quality, temperature, pressure, battery quality, radio components, programming, etc. which must perform perfectly for this to be successful. One of them will fail at some point. In a nutshell, when you turn off your transmitter, you are endangering yourself, the people who maybe nearby and the very hobby we all enjoy so much. Will your quad, while flying in RTH mode be the one which falls out of the sky and causes a severe injury to a friend , neighbor or young child? Will you tell them it wasn't your fault because you were not in control of your aircraft? Again, please, think about what you are doing and what you are risking and fly more responsibly. Thanks for your time - Mark |

Rth?
The people that don't even want to test the RTH function should probably consider just disabling it. You never really know it is working until you actually try it. The NAZA is pretty simple compared to most autopilots, but there are still a lot of variables involved. Different transmitters, receivers, etc. not to mention a manual translated from another language for most users here.
Obviously you can test first with the Assistant software. If you really want to be careful you can then tie your copter down, maybe remove the props, power up, go to failsafe, and then quickly try to regain control so you can be sure how that works. If things don't go as expected just disconnect the copter's battery. Eventually though you just have to do it for real. As for NAZA RTH failures, it's probably just like anything involving humans. Most are likely "pilot error". But with untold thousands of NAZA RTH activations by now it certainly quite possible (probable) that hardware and/or software failures are to blame for some. My first test of RTH was a failure. Upon turning off the transmitter my F330 immediately rose to ~20 meters, stopped, rotated to face me, and then took off in the exact opposite direction of what should have been home. Maybe it was going around the long way . Turning on the transmitter and toggling the flight mode eventually got it back under control. What if that didn't work? Well this was a remote area. The possibility of it doing any damage was essentially zero. After that I went through the setup and manual again, couldn't find anything that I should do differently, and eventually went out to try again. This time it worked as advertised. I've done it more than 30 times since. All worked fine. Was the first failure user error? It's possible, but I don't think so. The interesting part of that test - besides flying off in the wrong direction - was the immediate rise to ~20 meters. Every test since has had the ~3 second hover before starting RTH. This makes me think the NAZA was confused on that flight. Any RTH test I've done has always been under ideal conditions. Just because something can fail, perhaps from no fault of your own, doesn't mean you should avoid it. Manned aircraft crash every day. Most people still fly. A few don't. Maybe in the context of the NAZA those type of people should just not set up RTH. For the rest of us do your homework and test it out. It's going to work fine almost always once you have it set up correctly. Do keep in the back of your mind though that the NAZA can, perhaps on very rare occasions, fail just like any other component associated with your copter. |

Firstly every multicopter on the planet is flying under total control of the flight controlller. The pilot is merely politely ask the quad to move in X direction, climb and/or decent.if that controller wants to hold your copter at 45 degrees and fly off it can happen at any time. Secondly, RTH is basically a one waypoint mission. Is DJI waypoints (ok Wookong not Naza but hear me out) for emergency use only? Of course not. Hell even position hold is computationally the same as RTH, it's juat that "home" is where you're at. Is position hold for emergency use only? I think most would say no. Then you have the chances of pilot error versus code/gps error (variable at best).... With respect, you don't seem to know enough about computingor real-world objective risk assessment to be making such bold sweeping claims. |

It's easy to safely test the failsafe. If you don't test it then it probably won't work. |

[QUOTE]With all being said, would I trust Naza?
The answer is Really not much. Every time I take off, I say this in my head "Will this come back in one piece?" QUOTE] +1. Man, I have EXACTLY the same feeling. I have started flying FPV with my machines. I put the goggles on, and stare at the beautiful scenery all the while wondering ifwhen I will see an uncontrolled fall from grace. |

The microcontroller that is in charge of your car ABS brakes is probably cheaper than your Naza controller, yet, you drive every days without even thinking about it even if your life depend on it.... I agree with MCrites, like a car, there's so many parts that can fail, that worrying about only one is pointless.

I don't have ABS. When given the option I never choose it because it actually increases your braking distance. I'd rather control my vehicle myself and steer around a crash. Anti-Lock Braking System should have been called Anti-Lock Steering System because it exists just to keep the wheels turning so you can steer. I guess though the acronym for Anti-Lock Steering System wasn't PC enough.
I guess I just trust me more than the machines in most everything. The same goes for the Govt... |

Hopefully you will be able to do that with blocked wheels. Most people tend to kick their brake pedal too hard in case of an emergency, so that the wheels are blocking and there won't be any possibility of steering then - that's what ABS is for.... I've driven sportcars without ABS for many, many years and I really like What ABS can give you in case of an emergency ( same with NAZAs RTH :-) :-) )
