Either way will work. The most common is AERO.

I set up my Naza using Heli mode. That way I can use my flight modes to give me the 3 different positions for Man, Atti, and GPS Atti. Then I use hold to give me failsafe.

I tried to get it programmed on my Spektrums (DX8,9, and 18) in acro mode, but couldn't figure out how to get the failsafe (go home) switch to put it into come home mode from each flight mode position.

If any one has a good mixing formula to do that I would appreciate the info.

Thanks

thanks
I was thinking of using Heli-mode as well. Is there some good instruction on how to set failsafe mode (home) ?

I learned that technique from a buddy. With heli, you just set straight line pitch curves and assign the U channel to your flight mode switch and CH 6. Then your U value will remain at whatever pitch curve setting throughout the entire throttle range depending on which heli flight mode you select (N, I1, I2). Then just set your throttle hold switch value to give a pitch curve value that is in the failsafe range.

There is no complicated program mixing required, and the switch values always go to the same position. If you use acro or aero mode, then you have to use channel travel values for the mode switch and whichever channel positions you use. If you are using a Naza, the U channel can be plugged into any channel above 4 for the mode activation. Some older transmitters don't have the flexibility to assign all channels like the DX9 and 18, so that could present some obstacles. But my biggest problem was trying to get the failsafe mode to activate from any mode switch position using program mixes. I either had to give up using the manual mode for acro, or couldn't switch into failsafe from one end or the other.

It just worked out better for me to use the heli mode and use the different flight mode values for control of the Naza.

cool
Makes all the sense.

So straight pitch and throttle curves.
Set Throttle hold value (lets say x%) which is same as failsafe setting for throttle position, and when I flip that switch, it will come home ?
And ofcourse I need to figure if that x% is good value for a smooth safe landing. Just for idea, What is your throttle hold setting ?

I will be using Airtronics SD-10G, You can assign any switch to anything there

Thanks for some good advice.

No, not straight line throttle curves. All throttle curves need to be 0 at low stick, 50 at mid stick and 100 at high stick.

Since you are plugging the U channel which is the Naza mode channel into the pitch (aux 1) channel, all your throttle curves need to be the same from 0 to 100%.

Sorry I didn't make that clear.

I just checked and wanted to make sure I was giving good info. N, I1, and I2 throttle curves are all 0, 25,50,75,100 and TH is 0,0,0,0,0.

The pitch curves are N=8,8,8,8,8 I1=50,50,50,50,50 I2=91,91,91,91,91 and hold is 30,30,30,30,30. That places my slider in the Naza assistant in the middle of each of the ranges, and it will be somewhat different since you are running a different radio system, but I think it should be fairly close.

thanks
Sorry I meant linear not straight .

I will give other settings a try. Thanks very much for gettin back with more information.

Another QQ. I will be connecting a 4s pack . What is powering the Naza unit and receiver ? Do i need separate battery ?

There is a built in BEC in the setup. On the new Naza V2 it is called the PMU, on the older Naza and the Naza Lite, it is called the VU (versatile unit), and which ever one you have, it powers the receiver and the main Naza controller.

Since you are directly connecting everything to the power distribution tabs on the frame, there really isn't much current going through the BEC like you would have if there were servos (a bunch of) attached.

The software assistant and the manual (quick start guide) are pretty self explanatory.

Good luck.

update
Thanks for all the info. I was able to use the flight mode button to set GPS Att Manual Failsafe in MOde 1,2,3,4.

Any idea how do I test failsafe ? should I just hover it and hit failsafe ? I have it set as return to home and land

That's how I tested mine. Just DON'T do like I did and initialize its home position under a tree!!!! Scared the crap out of me after I flew it out into the front yard and then tried the home function. It did just as it was supposed to, climb up the 60 feet, motored over to above the top of the tree, and started down.

Luckily, they don't descend real fast, and I was able to bail out, but had to go back inside for a while to calm down. Can't imagine what I must have been thinking at the startup to be under the tree.

I tried adding expo to cyclics and it did calm down the copter. A lot smoother and forgiving.
