This is a bit of an aside. I just took a good look at my puck under a magnifying glass. I am having a hard time identifying the fastener DJI is using. It almost looks like the screws are torx with deliberately mangled heads. Can anyone shed some light on this? I have used DJI technology for quite awhile and my experience is that it is engineered to stand up to the entire New York Jets offensive line. Embedded systems technology is pretty tough these days.

Hmm... The problem I see with that is that every physical connector introduces a potential point of failure due to the physical nature of electrical contacts. Hard wiring is the way to go whenever possible.

I was waiting for the wind to go away, but in Palmdale that can takes weeks. So with 14 Kts advertised at the airport 4 miles away, I wanted to show it off to visiting family.
I'll make a test flight with the Helicam Solutions mount this weekend and then post it for sale. I just bought a Bergen Observer and need to placate the spouse. |

I had a closer look at the setup software tonight. I guess I didn't see the message earlier, but I'm getting an "Other Err[25]" in the lower right hand corner of the set up screen. I also noticed that one of the accelerometers is "stuck" at -16. All other gyros and accelerometers respond to movement. Obviously the boom strike did more damage than just tear off the GPS unit. I sent out another email to DJI sales and support... If I get a response, I'll let you guys know how it goes... |

After seeing the "Other Err[25]" message on the setup screen, I'm beginning to think amongst the same lines... The blade cut and shorted all the wires together, resulting to a total system failure.

At the very least, allow users to open the puck to replace the cable at the solder points. But it sounds like they aren't interested in that, since they used security screws. I really don't understand the point of that. This is going to happen to people *a lot*. Quote:
My guess is that the shock made that puck move too far inside the case and it damaged the ribbon cable. Just a guess. Sucks that an already expensive helicopter crash just got $400+ more expensive.

This is the first time I've ever seen the GPS unit (from any version of DJI product) getting damage from a crash though.

I've yet to have a boom strike in any if my flying/crashing too, so while it most certainly can happen I think it was just quite unlucky here.
Generally speaking boom strikes are not all that common unless running too low head speed, blades too loose in the grips or some seriously hard flying with dampers that are too soft.

Very true. I have crashed my heli no less than 30 times while testing things. Not once have boom strike.

I'll give you points for bravery. My handbook on superstitions warns against displaying heli piloting skills to visiting relatives, especially the spouse's relatives. Such things could anger the heli-gods.

I have received an email from DJI asking me to give them my dealers name. They are going to start working at the dealer level... Until then I will have to wait and see what happens from here. I will keep you all updated. I have seen a GPS protector amongst the Naza-M crowd... Any thoughts on this? http://www.rcgroups.com/forums/showthread.php?t=1746472 |

But it is a nice idea for multi-rotors.

NexxuSix that's kinda crappy for the money spent on that thing, just a boom strike and it failed the IMU also? And they won't at least replace the IMU? I was thinking of getting one also but not after this story. I once had an mcpx that the main board failed on from about 50ft up, it hits the pavement hard and parts go everywhere. I send it in a box to Blade and they replaced the entire heli...no charge. DJI should at least replace the IMU for the 2 hours you got to fly the thing.

Has anyone put a connector block on the GPS cable or soldered in an extension? I can't see an issue so long as they are good joints they won't affect resistance.

I know there has been a message or two regarding folks who have shortened the cable a bit. I would want to really inspect that cable before doing anything to it. My stock connector goes across four pins. I assume that means four wires by the look of the connector. What I do not know is if there are twisted pairs? Wires are twisted in pairs to counter-act an electrical effect known as cross-talk which is a signal in one wire interfering with a signal in another wire. This twisting is done if the signal on the wires has a frequency component. I do not know if the GPS signals have a frequency component when they travel between the puck and the Naza unit. If those wires are in twisted pairs, undoing the twists to install a connector block or extension may cause signaling or cross-talk problems. If the wires in the cable are untwisted, there may be no concern.

Guys, is it possible that we haven't even begun to explore what is REALLY possible with the NazaH/GPS? This is no mere pipe dream. Check out the Raspberry Pi computer. Check out its price ( real cheap), its size, its power requirements and its ARM processor. This is a full powered computer that is adaptable to our multi-rotor platforms. Just think of the possibilities for what we do. My usual UN-reliable sources tell me that Naza is also heavily involved in ARM processors and Linux. As I see it, this is just the beginning. These two technologies can take us a very long way past anything Wooking Waypoint can do and do it a LOT cheaper. We now have the technology, the price and the brain power.
