DJI Naza H

Ya, I've been spending a lot of time searching information. I think it is new enough that guys are still tweaking their settings. I'm following threads over on Helifreak and RCGroups too.

These are for the Naza-M but they may also apply to the Naza-H.  Thanks to The Roswell Flight Test Crew.

BTW: If you have a transmitter with knobs you can set the gains to try trimming in flight then lock them down at that value if you want.

I've got new tail blades now and ready to try again in the morning. I lowered the TX gyro gain to 40% and it's also 40% HH in the Assistant.

John, did you get the chance to see if the other settings on yours was above or below the default 100%.

I'd been pretty seriously kicking around the idea of selling my 500 but after seeing what they were going for used on ebay, I've changed my mind. So....... since I still had a little hobby $ in the stash and HeliProz has a 13% off deal I bought another NAZA for the 500. 
Any one need a good mini V-Bar?   

Hi Bill, I just looked right now and here is what I am using on my Naza-M on my DJI F550.

Autopilot Tab

Basic Gain:
Pitch =  160%
Roll =  160%
Yaw =  160%
Vertical =  160%

Remote Adjustment = (all) INH

Attidude Gain:
Pitch =  100%
Roll =  100%

Remote Adjustment = (all) INH

The NAZA assistant may be a little different with the heli version. Here are a couple of screen shots on the common page.
The first page shows default settings still all at 100%.
The second is the advanced settings of the same page and it show where I changed the tail gyro settings to 80%.
At the bottom of both pages you can see I was in GPS mode with gyro in HH at 40%.

The Naza-H assistant layout is quite different but the settings may be similar.  I wonder what would happen if you increase the Front/Back Left/Right and Vertical to say 120% as a start and work up from there?  They seem to be the equivalents to the Naza-M Pitch, Roll, Yaw and Vertical settings.

That's what I was thinking, just wasn't sure which direction to go to start with. 

I experimented a lot to find my settings.  In my case, because I don't have any knobs/levers on my DX7SE transmitter, I had to do a lot of plugging into the computer, fly, plug into the computer, fly, etc. to find what worked best for my aircraft.

In a way I don't envy you because with a quadcopter or hexacopter over or under tuning these and having a crash might lead to a few broken cheapo propellers...not the same situation on a 600 size helicopter!  Be careful and good luck!

Yes indeed. Thank you.

In my case 5% changes were barely noticeable so I ended up doing 10% increment changes.  However quadcopters and hexacopters seem to be more inherently stable than helicopters so you may want to use 5% or lower increments as a starting point and see how your helicopter behaves.

I got this thing flying well again John. 

After countless trips from here at the PC to the back yard I ended up with 30% gain in the TX and it shows the same on the assistant.
The AutoPilot gain in forward/back is at 55% and left/right is also 55%.  (A laptop would've been nice. :)

I'm getting a little of the TB effect even though I've reset the GPS with about 15% offset but I'm thinking it has a lot to do with the way the wind comes from over and around the house.
Tomorrow I'll try to take it out to some open ground for a real fly around.

That's great Bill!

Hmmm... I don't think so on that one Bill.  I can hover in some extreme wind and although the hexacopter will get blown a little away from the GPS hold location it will fight the wind very well.  Seriously I have hovered in some wind so strong it was scary and you can hear the motors under Naza control fight the wind to stay in the GPS lock place.

I am surprised with your 55% gain values.  I don't think anybody with a Naza-M uses less than 120%.  maybe some of the other guys here can chime in with their values.  Maybe the Naza-H is different.

Did you try anything over 100%?

EDIT:  When you entered the GPS antenna position did you use a negative value or positive on the Z axis?  Are you sure you have the X and Y axis correct?

I think it is, how much so is hard to say unless we could check them side by side.

I did not.
If it doesn't preform any differently in open air I'll give it a go the other way. Running back and forth to the PC is a real pain though. 

Amen to that!  I can't even remember how many times I tried sneakernet tweaking my GAUI 500X!  Maybe 1 Pspm (Pair of Shoes Per Model). 

The air was quiet around the house today so I stayed here to be close to the PC.
I did many more flights (hovers) adjusting the autopilot values again, this time starting at default 100% with the front/back then left/right.
It turns out that lowering the left/right value was all that was needed and is now at 40% down from 55 yesterday, front/back is back to 100%. It works well in both atti and gps.
I had one instance where I switched to gps and it slowly drifted further than I thought it should so went back to normal then switched back to gps again and it held then. That was the only thing that was out of the ordinary.
I think it's going to be a keeper. 

Great!

I have seen that behavior many times...drifts a little then settles into a solid GPS lock.  I see it more when I am near tall trees or near buildings.  I usually can wait for a lock at low altitude, or hop up to tree top altitude and get the lock relatively fast(er).

Did you ever try any values over 100% or 120%?

I did not John. When I got back to 100% the problems came back but this time I did most of the testing right here at the PC watching what the swash did as I switched through the modes as I decreased the AutoPilot gains. There was a noticeable change (less) in the right tilt of the swash as the value of the left/right gain went down.

I have no idea why this is working for me because others I have chatted with say they've had no luck doing it.  ???

Every model is different.  Main thing is that you got it working stable.  I am looking forward to seeing a video, or hearing about your full flight reports.  I think the Naza-M is the best flight controller on the market for multirotors and I'm hoping that the Naza-H might is as good for helicopters  Maybe I'll finish that JR Vibe 500e afterall.

Do it John, I'm sure you'll be glad you did.

I will work on getting a video but it won't be right away, I've spent something over a week playing with this so I had better take a short break and get some other things done.
