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抯 basically a $130 firmware upgrade for a DJI flight controller that抯 a single download away. Some reason i deleted link if anybody want please pm me

I was also foing through this since some time now..have you trued this..

Yes i have gone through the details too.. kind of unable to decide whether to do it or not

Is it reversible ?? if not i wont prefer to do so ,  but v2 is lil more stable than lite ..

They say its reversible..but i am in a dilemma whether to take the plunge for more stability or stay put

V 2 is more stable than lite and it has octa copter option too

all that is fine gaurang.1972 but what if it gets bricked ...still I am thinking of doing it next week..

hello rc bhailog ,, i've already upgraded my lite long back and i must say , the change is noticable,
the process can be rolled back - you can downgrade to naza lite and fly asiff nothing ever happened, i suggest you guys should give it a try,
after upgrade, mine stopped drifting, and no aileron / elevator inputs needed wile take off ... loving it ..  
this website should clear all your doubts . http://naza-upgrade.com/

can i use waypoint feature in a upgraded naza m lite without data link modem. in software update site i saw that they says u can use waypoint feature with dji data link modem. but can i use waypoint without data link modem by using usb data cable?

Hello, are we still able to upgrade naza m lite to naza v2? because some blogs and videos in youtube says that they were unable to do it now.
is it so or is there a way to do it?

it should work. site is online and process is straight forward. v2 is stable and GPS fix takes less time. i see huge improvements in performance. here is the video taken last year with v2 loaded on lite.

Thank you. I purchased a DJI naza m Lite recently and will receive it in few days.  I will try to update it to v2 and will post the result.

Hi guys, sorry to resurrect an old thread, but am looking forward to upgrade my Naza mlite to V2, but am somehow unable to access the website http://naza-upgrade.com. Is there any war around this ??

above method worked to upgrade firmware 4.0.0 to 4.0.2 but there are two new firmware versions were out 4.0.4 and 4.0.6. One more tool available to upgrade lite to v2 which is easy to downgrade as well. Please check here. One of my lite upgraded to 4.0.6 using this tool.

hi, thanx a lot for the link, I downloaded the utility and ran it as suggested, my FC gets detected, then it says initialize update procedure, but since then it's been sitting idle for over 20 minutes now, did something went wrong?

am trying to update v4.06 on a naza m lite

it won't take much time, I mean couple of seconds. please have a look at this video, there some more videos but I quickly followed this one when flashed mine
