Records home position but crashes to the ground :(

Hi,

My naza m v2 looks liek it records the home position (rapid green blinking), but if I tur off the transmitter is just comes crashing straight down.

Normally, after the rapid green flashes, I see two green flashes and thats how it stays during flight. What am I doing wrong?

have you programmed the fail safes in the assistant software? Check in the software the when you turn off your transmitter it does go into failsafe. Also note that the rapid green flashes means that it has recorded course lock not the home position. Make sure you have no red flashes before take off to be sure you have enough satellite locks

Also, somewhere in the Naza manual it says you need to set the Failsafe of your transmitter to provide >10% throttle.
I'm totally guessing, but do you have "immediate" shutdown selected instead of "intelligent" shutdown in your assistant software? That, along with your receiver not setup for a >10% throttle on disconnect, might account for it just falling out of the sky.

Easy? You call that easy?
And don't turn off your controller in flight! As above check everything on the assistant first. If using Spektrum remember to rebind with failsafe set.

Oops sorry, I thought that was a way to test it. I am very new to it all.

What I have noticed in the assitant is that I set my 2 way (dx6i) switch to GPS and manual so I was able to get into compass calibration but the status bar at the bottom say GPS Atti, is this different from GPS?

I have now set to GPS (although it still shows GPS Atti in the status bar) and failsafe so I will test that but I still need to be able to GTH if for example by Tx packs in. How do I re-bind with failsafe set, i dont fully understand that.

I never put it in the air with a red liht showing. I have selected "Go Home And Landing" in the F/S tab.

I don't know how to do that. I have intelligent shutdown selected, I dont ever want my motors shutting down unless I tell them too, am I right in thinking this is what intelligent mode is?

I just looked at my Tx, there is no failsafe option that I can see.

GPS and GPS Atti are the same thing... DJI just likes to confuse us all. ;)
Failsafe can be tested many ways, but as Ben said, don't test it by turning off the transmitter til you know all the others work. And you'll want to verify it all through your assistant software.
You will want to setup your transmitter/receiver for the Flight Mode to move into the Failsafe region. You can still keep your Manual selection if you wish. Two things other operator do are: 1) tied in a second switch to force the U input to the Failsafe region, and 2) set the Failsafe value in the transmitter to output a value in the Failsafe region for the U channel.

Im more confused than i was before now :D I have set the gear switch for GPS and Failsafe now but I'd like it to just go to failsafe when Tx lost rather than having a switch (I dont see why you would need to manually switch to failsafe if you still have comms to the Rx). I dont see any failsafe option on the Tx and I don't really know how to setup another switch to do the U input thing you suggest.

thurcombe, sorry for confusing you. I'll try to explain myself a bit more.

There are multiple ways to get the Naza into Failsafe mode.
1. The easiest way is using the Naza Software Assistant, you can configure the U channel to be GPS, ATT, FS, and giveup usage of MANual mode. I personally do not like this because I want Manual mode available if I need it.
2. Setup the Naza for the U channel to be GPS, ATT, MAN, but then have the transmitter send a value (based on a switch) for the U channel to be in between those three mode into the region called Failsafe. This is something external to the Naza, and requires special programming in the transmitter. Sadly, I do not know the DX6i transmitter, so I can't help there, but I would search YouTube; that's where I found out how to do that for my Futaba. Basically you are going to do a "mix" of two switches. One three-way switch that commands max, middle, min values which associates the three positions to the three flight modes. Then you "mix" in another switch which adjusts that same output of the 3-way switch to force a value in the in-between area. This way you can trigger the Naza into Failsafe with this other two position switch.

The above two methods are the pilot triggered ways of getting the Naza into Failsafe, and it is advisable that you setup one of those two. However, there is the true Failsafe intent which is the case when communication between you and the Naza is somehow broken, typically because the receiver is no longer receiving the signal from the transmitter. That is the transmitter/receiver failsafe programming that everyone should also setup. If this is setup correctly, the Naza failsafe will kickin if power is lost to the transmitter, or the signal is lost because you flew out of range. Again, I don't know the DX6i, so I can't give you specifics. But the jist is that you program each of the outputs to a specified response if communication is lost. So on my Futaba I have the throttle output set to 25% if the signal is lost, and the U channel set to a value that puts the Flight Mode into the Failsafe region.

So all of the above settings/programming should be verified on the ground with the Naza Software Assistant running to confirm the Naza flight mode is truly "Failsafe". Then, once you have confirmed that, try invoking Failsafe with one of the switched methods. Once you have confirmed stuff and you feel confident, then maybe you can try the loss of power method, but just be careful. I have tested it that way, and as soon as I confirmed it was returning back home, I turned it back on just to give me that piece of mind.

As to another question you had earlier... "Intelligent" shutdown is what I prefer, so you're fine there. I was just wondering why your MR just fell to the ground, and I'm guessing the Naza is getting a zero throttle input when you power off your transmitter. You can double check that with your Software Assistant.

Hey hey. Good, a Spektrum man. So, binding. Quite easy really. First in the assistant have your 3 position switch light up the failsafe option. Turn everything off. Insert bind plug into receiver and power up. Remove bind plug. Your transmitter sticks should be centred including throttle and 3 position switch in failsafe position. Turn on transmitter with bind button pressed for 5/10 seconds. Receiver light turns solid. Now turn everything off. Reconnect to assistant. Now if you turn off your transmitter the assistant should show it in failsafe mode. Bingo.

Make sure you do the calibration of the sticks and that all the little sliders are green when you press finish. Do this before the failsafe stuff I mentioned.

There's loads more but I hate this typing on an iPhone whilst on a bus thing. I learnt from various YouTube vids. The German dude had a good explanation. You'll see.

Cool?

Guys thanks for your replies but the DX6i doesn't have a three way switch. I tried doing the mixing thing to give me three positions spread over two switches when I was under the impression that I needed to select between all three to get into compass calibration. I couldn't get the mix to work (and then someone told me I just needed GPS/Manual for the compas thing) but it looks like I will need to sit and play and spend some more time on youtube. Problem with that is you start watching videos on configuring your transmitter and three hours later, somehow you're watching elephants playing football... damn youtube.

Well I have been through 4 or 5 vids now and no matter what I do I cannot get three unique modes selected with mixing. Using subtrim and travel adjust I can get the gear switch to select between GPS and failsafe, with the mix set to try and get to the end of the slider to select manual but it is impossible. My mix rate up is +125 which is its max but it is not going far enough to highlight the selectable dropdown.

This is extremely frustrating :(

Actually, scratch that, ive got it :)


I need manual for compass calibration, is it possible to now mix another switch in there to take me to atti mode?

Now I finally managed to get the 3 position setup for failsafe so I followed your procedure, the assistant does not show failsafe when I turn of the transmitter, just GPS atti (or whatever mode I had selected prior to Tx shutdown).

This is driving me nuts.... I just took the 550 outside to see if the failsafe switch would initiate RTH but instead I am presented with rapid orange flashes, meaning Tx lost... WTF? If Tx was lost how come the Tx commands are showing fine when connected to the assistant.

It really shouldn't be this difficult :(

400 quids worth of naza and its not smart enough to work out itself when the Tx is really lost and just apply RTH with 10% throttle or whatever it needs.

Edit: Ok so I am an idiot, the rapid yellow flashing might have had something to do with having the failsafe switch enabled :05.18-flustered:

The damn thing still won't go failsafe on TX poweroff though and I've been through benjamins procedure several times now.

I feel your frustration. Don't give up, it'll click. I'm sure Ben won't give up until you're up and running with your Tx/Rx setup.

Yeah I am sure I will get there with some help from you guys here :) On the plus side it's not as frustrating as CP heli was, at least I can fly the 550, although I still get a bit flustered when things go wrong and she is facing me (I know I could use IOC but I figure that's cheating).

I'm keen to see how much range I can get but there's no way I am pushing that until I know it will come home on its own, that said im not sure range is a problem as im only getting about 7 minutes flight time (Turnigy 3s 3000). Kind of O/T but I guess I will get more flight time by putting two of those in parallel (but im guessing it wouldn't equate to 14 mins in the air)?

Yes, putting two in parallel won't double the time just because you're adding weight.
I don't think you'll be outrunning your transmitter range really soon, but it's still good to figure that out.
Ben, can you help thurcombe figure out his transmitter failsafe issue?

Would moving from 3000 to 5000 batteries help? That's 7 mins before adding a gimbal and camera so I'd definitely like 12-15 minutes before adding the weight.

Ben, im not sure how relevant it is by my Rx is an AR6200

Morning! Once again, don't practice flipping switches at the field if it doesn't work in the assistant. Why would it be any different? You don't need a 3way switch. Just program a two way for say GPS and failsafe. Use this to bind in failsafe mode. I personally have never activated failsafe from a switch with Naza. Just when it goes out of range which is about 2km with Spektrum. Or if you go behind a couple of trees.

Adjust your dual rates (D/R) until the switch activates the correct segment on the assistant. I imagine the flashing orange light is because your switch is somewhere in the nowhere zone. If it flashes once every few seconds then that's ATTI mode.

As usual I'm writing this on the bus so sorry for poor explanations.

I spend a week or two bench testing and understanding a new craft/system before I think about flying it. I spent about 10,000 hours reading 'on the line' (yes, online) to get to grips with things.

You almost blamed DJI at some point. Don't blame the equipment! These things are not ready to fly by any means.

We've probably all been in the position your in right now. Most problems can be fixed by reading.

Later on I'll look for some helpful info for ya.

Coolio?

Hi Ben, thanks for coming back, I think there is a mix up somewhere.

I know what you're saying about the 3 way not being needed, I want it though to be able to select between more flight modes. Either way that part is sorted, ignoring the mixed switch, on my gear switch I can select between GPS and Failsafe now although the ONLY way I could get this to work properly was to reverse the gear switch in the Tx setup.

The rapid orange lights was my fault, because I had the gear switch set to failsafe.

The only problem now is that after your binding procedure, if I am in the assistant and turn off the transmitter it does not show failsafe. If I toggle the gear switch is shows GPS and Failsafe accordingly but switching off does not enter failsafe.

I followed your instructions to the T, first setup the gear switch to toggle between GPS and Failsafe, turn everything off, remove usb cable from naza. Insert bind plug into Rx and power up, then remove bind plug. Next I checked that my gear switch was forward (so in failsafe), powered up with the trainer switch held forward to initiate binding, release and control is binded (bound?). Turn everything off, plug back into assistant and power everything up, change flight mode to GPS then turn off the Tx, the status in the assistant still shows "GPS Atti" or "Manual" if I try turning off the Tx whilst in manual mode.
