DJI, the company that gave us the far too popular Phantom line of quadcopters, doesn抰 just make the most popular line of FPV quads. Their top of the line flight controller, The Naza V2, is very good, able to connect to flight planning software that will set waypoints, talk to peripherals over a CAN bus, and has improved flight algorithms. On the other hand, their 憆educed price� model, the Naza Light, can抰 connect to these nifty CAN bus peripherals and has a bit of a problem with drifting the quad from one side or another.

The Naza V2 sells for around $300, and the Naza Light sells for about $170, both with a GPS module. The hardware inside the V2 and Light is exactly the same. We all know how this is going to go down, right?

[udnham] over on the RC Groups forum figured out a way to load the more capable Naza V2 firmware on the Naza Light, giving the cheaper flight controller features that were, until now, only found in the more expensive V2 hardware. The upgrades include better algorithms for GPS position and altitude hold, the ability to connect to DJI peripherals including the Bluetooth module, the iOSD, and camera gimbals, Octocopter support, the DJI datalink modem, and a bunch of other features.

Even though DJI is using the same hardware in the $170 Naza Light and the $300 Naza V2, upgrading the firmware requires an Internet connection to the DJI servers. [udnham] wrote a utility that modifies the /etc/hosts file on your computer, runs a service, and allows you to upgrade your firmware on the Naza Light. It�s basically a $130 firmware upgrade for a DJI flight controller that�s a single download away. For some reason i deleted link if any body want pl pm me

hi,

i have 2 naza mlites and both are having major issues.

the flight pattern is very unpredictable and at times it looks very stable.
on the other hand it starts driftling badly on takeoff and is totally out of control.

have grounded both the controllers and looking for a major solution.

YOur link seems to be a good solution but i am curious to know if this works and also
whats the cost for upgrade.

have you tried it.

I did this upgrade yesterday..  n trust me its awsome... i'll make a video tomorrow and post it for your reference

Awesome news bro so it worked !! So its worth taking the risk (-:

the upgrade process takes less then 30 seconds..except for the software downloading part.. i have never flown on a naza lite.. I straight did an upgrade.. and the quad was extremely stable from the very first takeoff.

Sometimes in life taking some amount  Risk is worth it  ! But for the rest for it !! You bang your head LOL

hi,

Hats off to the genius who gave solution of the upgrade.

Thats good sandeep bhai 

hello frnds..
today i tried to update firmware. it successfully updates and says power cycle device.. i did but the firmware is still 1.00 and naza lite assistance software shows update available..

current version. 1.00  upgrade available 1.00
i update many times also did upgrade in safe mode.. but the same issue...

help plz... here i am uploading pics..

any other programs using port 80 in your system?

@gunnu.. bro are you running the hack tool or not.. you got to keep it running and open...

will show current version 1 and upgrade to 4.02(not firmware 1) in upgrade dialog box.


also disable antivirus may help(some of them can mess with this process).

Edit: more info added below.

can be checked using this command "netstat -a -b" in command prompt window to know any other program using port 80

and don't forget to right click and click run as administrator on naza-upgrade while opening(without admin privileges this tool will not work in win 7/8)

update successful tried in other lappy and it upgrades.. don't no y i wont update in mine...

after upgrade facing an issue ( don't no its an issue ) in gps and atti mode when i provide throttle the motor speed remains constant till it reaches 60-70% and after that sudden increase but in manual mode its working properly...

This is a new take-off feature for V2 naza.. callibrate ur TX and the motors will increase speed just above 50%...and take off at about 60%

bring back the throttle to 50% after you have attained desired height.. your rotor will stay there rock steady (in GPS mode)

i calibrate it but when i provide throttle to 70% motors gain speed but when put back throttle to 50% motors speed returns to idle...

Check your throttle curve.. set it to default

throttle curve is default...

make sure hovering throttle must be between 40% and 60%

ok thanx... tomorrow ill test and reply...

Gunnu solved problem or not?

not yet bro...

U call nileshbhai

can you pm me his contact no...

Check your phone sms

i checked but doesn't receive any message

I give u this afternoon after i call u send again just now

on which no bro...

Check your pm

got it thanx bro...

Tomorrow i test my hexa after updating v2 even in gusty wind drifting problem nere by gone good flying

Does it also supports the extensions

Thay called yes like v2 groundstation  and act same as like v2

yes, after the upgrade, its will be NAZA V2 (can be downgraded) . so if you wish to use extentions like zenmuse, can hub, bluetooth, iosd, first you need the naza V2 PMU as naza lite pmu dosent have can bus. hope this helps.
i'm verry happy with mine, my quad dosent drift anymore and is rock solid... 

Can someone help me to upgrade. i am still stucked in upgrading from M-Lite To V 2.

what problem you are facing??

It is not showing any thing. no upgrade available.

Here is a video link, but you may have already seen this, https://www.youtube.com/watch?t=16&v=fhRQAuyZ95g

What versions of Naza Assistant are you using? What is your OS version?

Preferably use:
Naza Lite assistant (v1.0)

Any kind of firewall can hamper this process, please disable firewalls and antivirus before running.

If successful use firmware 4.02, do not use 4.04.

Presently i am in naza 1.00 version which came as default. and in my laptop i am using windows 10.
 When i stop all the firewall and antivirus and run the program  it the update page it is showing no update available.

Have you logged in to you account from Assistant, i think that is a perquisite for upgrading. Also it's worth a try on another system with Windows 8.1 or earlier, can be windows 10 problem as it is a new OS, can't say what might have changed.

Have any one done the same recently? Yes i have logged in to my account.

subojit you should try windows7 or 8.1 but not windows10in windows7 it's automatically upgrade to v2

Ok let me try will confirm/or let you know.

No not true. I did upgrade a few times successfully in my win 10. Followed the standard procedure!

Hai i tried in windows 8.1 it worked. Thanks All
