Hi,
All my friends that flying NAZA asking me why i did not buy DJI NAZA as it work from the box.... I build my F450 based on APM 2.6 and still tuning it... Well it still fly like a boat on the sea.. Lots of oscillation etc. My friends have NAZA and they flying without problem :( What is so special with NAZA that APM don't have? I can't make an autotune because i use dx6i so do not know how to setup to make a channel for it... The worst thing is that they have less knowledge and experience then me in RC (i fly helis 600 and 450 size) and they are flying the quads with DJI NAZA and my quad is unflyable because those PIDs thing... WHY NAZA is ready to fly??
My setup, logs and video how it wooble...

What is Naza? ;-)
Is only question of good tuning and very little vibrations to your board, Naza has a cushioning system inside and Moongel is not always the best solution.
Of course, with Autotune you can lock your quad but you need a 7ch system.
Here APM Copter with my setup, very similar to yours, two layers of double-sided adhesive joint under the board:
Frame: $30
Motor: $15
Esc: $9
Carbon propeller: $6
You do not need a 7ch system. You can simply map a switch on your transmitter to channel 6, and connect channel 6 from the receiver to the ch 7 input on the APM/Pix.
Good point, is a nice solution with 6ch system but if there are excessive vibration Autotune does not solve it, first check your hardware, the software can not work miracles if the hardware is not functional.
I write this because it happened to me many times with friends who were reporting similar problems, almost always with poor hardware or badly set (not list all the reasons why I would fill the discussion, LOL).
Anything can affect, for example it happened to me that some self-locking bolts (for lock the propellers) were poorly made, unbalanced, and created incredible vibrations.
APM Copter does his duty if the hardware is ok, I have demonstrated many times on different setups, I got better results maybe DJI/MK.
Because I don't believe to be a genius if I can anyone can succeed there.
Surely Naza is less susceptible to hardware not too fine but Thomas, your setup is 100% DJI, tested by developers with Naza.
It's a bit like Mac OS X, fantastic s.o. and very stable, but one of the main reasons is that it has developed on the hardware for which it was sold.
Good hunting and good luck!

Hi Esteban, please in the future use the forum for this kind of request, thanks!
Yaw oscillation are induced by hardware, the F450 is too small to not have them.
Solution: 3 axis gimbal.
Your F30A are reflashed with SimonK?
Hi John,
I update the 1 post with more data. I use all stock from DJI f450 ARF kit. The Opto ESC can't be calibrated. The quad is flying but only problem is that woobling/ bout on water effect...
Thomas, if you could provide some additional specs such as props used, motors, ESCs', pictures of your setup even that would be a good start. Let someone here look over how you have everything set up, then go from there. Take some quick snapshots and post them. Pull some logs and post those as well. I am sure that there are viable solution to whatever problems you are having, just post more info.
As for the difference between the APM and Naza in regards to auto tune it all boils down to firmware and the actual micro that's running it. I
Naza= LPC176x series ARM Cortex-M3 MCUs 64KB SRAM, 512KB flash, 100+MHz,
APM= ATmega2560 8KB SRAM, 256KB flash, 4KB EEPROM, 16Mhz
Pixhawk= 32bit STM32F427 Cortex M4 256KB RAM, 2 MB Flash, 168MHz
I have always thought it impressive at what the APM's 8bit micro could do in comparison to more expensive 32bit controllers. I think that is the true testament to just what the devs and community as a whole here have accomplished.
I've add the update with first post with more data...
new pixhawk will killing all dji products!!!!
once all the code will be optimizate for this powerful processor, it will be the end for dji and others...
for now,my dji lite is not as good as my apm 2.5 for gps mode..but some things is better on my dji like loiter during fast translation..
"The end?" - Gosh, I hope not.
Competition, sharing of ideas, and a huge variety of products is what has made this field grow so fast. The day anybody contributing to multi-rotor design comes to and "end" will be a sad day. Especially if it's a company that really has contributed engineering-wise and business-wise. Let's hope they ALL keep moving forward.
