DJI Naza-H GPS Flybarless System

Would that be possible to take off & landing at gps mode since this shall be very safe
and convenient?????
align aps can do so why not naza h

The WKH offers this feature. It has been said by DJI that future versions of the Naza H software will include it as well. But not yet.

I currently use 2 JR satellite receivers and a 3GX on my 600. If I switched to the Naza-H GPS will it support satellite receivers?

Thinking about eventually getting more into FPV and looking for a bit more stability and the Naza-H seems to be pretty reasonably priced.

Not now. Only the new A2M multi rotor FC from DJI will do Spektrum satellites. It has not yet been released. DJI as a company has a bias toward Futaba equipment. I finally broke down and got a 8FGS to use.

I'm currently building a 10 foot scale jet ranger with the mechanic of the Airstar international mongoose. Pictures coming soon!

With that said and the assistance of Jack Cleveland, we have place the naza-h on the mongoose. Tried two test flight which has been unsuccessful with no crashes, ( thanks to the goddess of helicopter, LOL) The main problem is that the helicopter wants to tilt over on take off toward the right. I'm using so much input to compensate I'm afraid to left off. I have went thru all the setup as I done before with a 600 T-Rex, with great success. I did have the same problem but I can't find out what is causing it. The mechanic (pod & boom) is compared to a 800 plus, all servos is correct and the swash plate is level, all servos going in the right dirction.

So the million dollar question is why is it trying to tilt over on take off? Is this normal with the Naza or without the Naza?

You are trying to take off in manual I assume?

Perhaps vibrations? I know the Beast X could rip right if certain vibes were present...

Posted a short video of the Naza H on a larger gasser, not many on youtube at the moment. Also some flying in Atti mode for those asking how it maneuvers.



Also I'll chime in about the takeoff/landing in other than manual. There were several crashes when Naza H first came out from people trying that. Even Atti mode is not failsafe. If the unit is initialized level and is tilted even slightly as it spools up, Naza gives more and more cyclic inputs trying to correct until the head speed comes up and then its overcorrecting.

Although WKH has a governor feature, calling Naza H a governor is misleading. It locks the throttle setting, collective changes can make the head speed vary and I notice it significantly on my bird.

Hey guys,

I'm a little confused with the altimeter functions of this unit without GPS. Will this allow me to use a channel to activate it to not drop below say..... 10 feet? Will there be an upgrade to allow this on nitro helicopters?--As I understand it is only rated for electric for now.
Also, it seems this unit has a lot of features for a good price, yet I'm having trouble finding much info on it, because it's a new product?

[zeeflyboy]

No, there is no hard deck function.

The only purpose of the altimeter is to provide information for the Atti and GPS Atti modes.

When in manual, you have direct control over collective pitch to climb/descend.

When in either Atti or GPS Atti, you are now commanding a rate of climb/descent when you move the stick. It's a little like how the FBL system works with cyclic pitch in fact.... You request a rate and the Naza does what is needed with the pitch to give you that rate.

What this means for you as a pilot is that if you leave the stick at "hover pitch" in Atti/GPS Atti then the heli will neither climb nor descend regardless of outside interference or other control inputs. For example normally when pitching forwards to accelerate one would have to add collective to prevent the heli from losing height... In Atti/GPS Atti the Naza does this for you and if you try to add collective you will climb (since that is what you are now requesting).

The recommendation against use in nitro is due to vibrations I believe. If you have a fairly smooth ship then you can always give it a go, I imagine where it would really struggle would be gassers.

Thank you for the upgrade ... wil test it later today....
