You need a 7 channel system. 6 won't give you what you need. Sorry.

any idea why is this happening? i am pretty nervous now on doing anything until i get some answer why is this happening. all you suggestion will be greatly apprec iated.

thank you!
It sounds that there is something wrong with the Baro sensor, or the Z axis of your GPS is off. Can you show a picture of your set up and the GPS axis settings.

Thanks for the info, Ed. But I'm afraid that still doesn't explain some of the weird behavior I that the model was exhibiting when I connected the Naza and ran through the setup. It could be because of some setting in the radio, or I might have connected something incorrectly.

1) In the Calibration section, the program didn't recognize rudder input. I assumed there was a problem with the rudder connection somewhere between the Rx and Naza, but when i reached the "Tail" section of the setup, the tail servo moved with my stick inputs.

2) In the "Calibration" section, the program recognized and accurately reflected my aileron, elevator and pitch inputs. But when I reached the "Servo" and "Feedback" sections, the servos didn't move with stick inputs.

Is it possible that these issues (among others) are all tied to the fact that I don't have the correct radio?

I guess my best bet might be to get the 9X and add Dragonlink when I can afford it. Are there any other relative inexpensive solutions that might work well for me?

It is hard to say without seeing you set up and screen shots of the issues you are experiencing.

check the system feedback in assistent software, I think something wrong in setup directions.

Hey guys. I hope you are doing well....

So I just set up my 6th NAZA (3m/3h) and am having issues with my tail (and I havnt even flown it off the ground).

Problem= upon spool up tail just begins to spin, like tail does a 360 around the body...it just does donuts on the driveway. The tail stick imputs do nothing. Throttle up increase rpm, but nothing from the rudder.

The tail servo passed the setup- feedback test= moved quickly in the right direction). Connection is in the correct rudder port, ground wire up,. All else looks right, of course Gyro gain in my Fubata 8FG is at 40% (played with higher and % and it did nothing at all, didnt go lower because 40% seemed so low (now that i type this i feel like i should have at least tried it).

Any ideas??
THANKS

Check the servo settings. Make sure that you have specified the proper frequency. The other thing that you can check is the mechanical connection. Make sure that there are no binds in the shaft. You can also adjust the mechanical connection to counteract the rotation. But I would do the other stuff first.

The vertical sensor is reversed, because you can not change this you must reverse your throttle from software and from your transmiter both , so that they agree with they vertical sensor (barometer) i had the same problem, it tries to correct in the wrong direction this is why it is jump up in the air the moment you switch to atti or GPS, or forces it self on the ground at high speed. I thought my naza was broken, but after some reading i got it work like a charm.

Naza H

I am flying a trex 500 with dx 10

Went through set up, heli sits well on manual but shoots off right and down when put in att. Or GPS. Also keeps loosing the bind on the spectrum 8 channel receiver.

Does anybody have any ideas please?

I went through the setups from scratch to try resolving a problem. Mine was dipping in atti/GPS mode too. The last setup had everything moving in the right direction, but when I went to atti mode with motor off, then tilt left it would auto correct the opposite direction. I must have things reversed. But it flies correctly after reversing the last page in the setup. The animated pictures are backwards but it flies correctly.

Hi there.
How can you tell if the vertical sensor is reversed and you have to reverse throttle in software and transmitter when everything looks like it is working the correct way in the software setup. Had some guys at my heliclub test my machine for first flight. None of us had used the NAZA before, mainly beast x flyers, and as soon as the copter was flipped into atti it forced itself to the ground. Machine now re-built and ready to test again but want to avoid the above again.
Thanks:-)

Hi,
I just bought a NAZA H and the setup of the Naza itself seems pretty straight forward, can anyone offer guidance on setting up the TX.. I have a FRsky taranis.. and its not very clear on how to do the Single Servoe 90 deg setup ?

Can anyone offer assistance with this ?

thanks

I always put the heli in manual and check to see what the swash plate does as I manually tilt it on the bench, then switch to atti and do the same thing. If I tilt forward and the swash goes backward I'm good. You can also raise the heli and expect the swash to go down trying to autocorrect. You can also turn the heli and see if the tail goes in the right direction.

Before I knew how to tell I bought a huge lazy Susan from bed bath and beyond and put my trex 700 on it. When it started going the right way it stayed still and built my confidence.

Ok, this may be a silly question but on the calibration screen when setting up throttle should the P and T be moving in same direction? My P slides right as throttle is increased and the T slides left as throttle is increased. If I reverse the throttle in my TX the both slide right as throttle is increased.
Also in the feedback screen everything works well but I get no response on the rudder feedback. Although it works fine in the Tail screen setup. Also, I have no rudder control once I switch back to the common screen. Any ideas what's going on? I'm using a Towerpro MG 995 analog servo. I plan on doing scale flying with this Trex600 CF with a Century 500MD Tow Defender body. Thanks

This sounds complex. To keep things simple, it sounds like your tail servo is connected to the naza correctly if its responding to the naza software. How are you connecting your receiver to the naza? Sbus? Traditional? It sounds like the rudder control isn't making it into the naza.

As for the throttle I use a traditional receiver setup and send throttle straight to my ESC. The ESC is setup for governor mode so the headspeed is maintained at a constant speed no matter where the pitch is. I can also use throttle hold the way I want it. Governor mode is the easiest way I've seen to do it.
