Morning everyone!
So i decided to try the whole Dji thing. It took all of about 20mins to swop the APM2 with the Naza.
The setup is as simple as it gets. That took no more than 10 mins.
After installing the hardware and software I took it outside and attempted the first flight.
All I have to say is wow! A truly awesome piece of engineering! Dont get me wrong, I love my ardupilot!
But the Naza is just amazing! Im not a very experienced pilot so im still a little wobbly flying the APM2.
The real reason behind buying the Naza, is for videography. I cant fly the APM2 stable enough for videography, obviously its perfectly suited for that, Im just not experience enough to fly it well enough. Duran DeV flies all his copters on APM and his videos are mind blowing. So its not the FC, its the pilot!
For a not so fresh noob, the Naza makes the whole experience a dream. I did a direct swop out of the FC on the standard jDrones Arducopter and it worked like a charm, no tuning or anything.
I only flew it in atti mode. Which I think is awesome for videography, the alt hold is accurate to within a few centimeters.
And when I put my gopro on it, which threw out the COG, the flight dynamics remained exactly the same!
I hope the Ardu boys dont get upset with me for posting this, but one has to have an open mind to all new tech :)
G:)
P.S. I bought a ST Discovery high wing foamy trainer for my APM2 for photogrammetry, so Ill post some vids and or crashes of that soon!

I have mentioned a couple of time that DJI stabilization and loiter performance is something APM should strive for. I know some people have achieved close/same performance levels, but that is definitively not the case for the average APM setup yet.
Finding the optimal gain settings with DJI WKM is dead simple. Start at 100% gain and assign the gain variables to X2/X3 inputs (assuming this is also possible with the Naza). Then map the X2/X3 R/C channels to variable pots on the R/C radio. Hover the multicopter and move a stick to a side and release it so that it falls quickly back to center. The multicopter should level quickly. Raise the gain using the variable pots and try again, until the multicopter starts to oscillate when you release the stick quickly. Turn the gain down again so that it is just below the point where it started to oscillate and you are done.
Notice all tuning is done it the air. I have never done any "hold in the hand" tuning with the DJI. Just start with moderate settings (100%) and it will fly just fine.
I also did my first FPV today! Will post when the vids are uploaded!
@Ellison, dude I absolutely LOVE the vario throttle!!! TX on, copter on. Wait for the led to flash green four times. Arm the motors, they start then put the throttle at 50%. If you dont do it within three seconds it automatically stops the motors. Then juice the throttle to 75% and off she goes. Reduce back to 50% and it maintains the altitude. On mine, within less than 10cm. Reduce to 30% and it slowly descends. The autoland lands the copter better than I do, could land on a buttercup :)
@PACEFE, With regards to loiter and nav with the arducopter. I havent been able to get it to work. With 5.5 code from mp, when I engage loiter it takes off with a mean speed to the left. I havent been brave enough to try any navs... Hopefully all with go well with my arduplane :)
@Chris,
I guess its time you find a better argument.
My APM 2 is grounded until 2.6 is released. Hope my best for this release or I will give up. Only problem I have is I wont llike to sell any one else a not working system, so I have to build a balancing robot to use APM with. At least crashes wont be that bad in this case.
I fly a 50USD multiwii and it does just the same as APM but without the crashes.
The only thing I could ever fly navigation with is Arduplane.
Now it looks that good navigation can be achived with Ublox 6 as shown by Mario.
Hope we all get the integrated APM 2.0 Gps replaced by the new one free....
Arducopter can actually not fly waypoints or rtl, at least as my quad concerns. Will be great to know how much people in this forum can do navigation and how many not.

Must be something with my DJI 550 setup. I've had bad experience with my Naza. Gareth, since you both flown APM and Naza. What's the deal with the "vario" throttle?
Hi Chris Hi Gareth,
i try NAZA ,too but my impression isn't that is so good in fly . The performance is same of us platform not so different. So the main difference is that is very poor in the advanced configuration Option .
So at the startup you can "only" setup the frame , only a check box and not need to upgrade a new firmware for change a frame. Setup the radio standard or ppmsum .
Then you have 3 gain not pid for pitch roll and yaw and a good failsafe.
Stop no other functionality . Then with gps update could be that this platform add loiter and return to home.
So i yet propose to randy some upgrade for frame configuration , only a parameter to switch between configuration , simple way to setup is ppmsum or ppm standard channel.
Then we need to do a better work on failsafe and have a simple version of mission planner for entry level user.
The other thing to do is conversion between gain to PID.
Best

@Chris. Agreed, but i dont need autonomy for videography. Im really looking forward to building my first Arduplane!!! *excited* :)
Looks great in manual, but too bad you don't have a real autonomous UAV anymore ;-)
