I just tested the NAZA GPS today, not quite what i expected.
I've been flying the NAZA in a custom build 450 size quad with this setup:
Turnigy park300 1080kv motors
Turnigy 12amp ESC
8x4.5 props from flyduino
3s 3300mha Turnigy nano-tech
3s 4500mha Turnigy nano-tech
I must say this is the most efficient and stable quad i flew. Even with the 4500 lipo + a gopro and video tx i flies great, i can do between 12~16 minutes flights.
Since i updated firmware to v2.01 things have changed a lot. I have built a F550 hexa with T-motor 2212 and Dji 30amp ESC and added the Naza GPS to give it a first try.
I'm having a lot of issues with it. Flight time has decreased a lot, I know it has 2 more motors and its heavier than the quad, but i was not expecting the flight time to decrease by about 50%.
I'm also having yaw issues and wobbling. And if it's a bit windy its way too unstable. I tried to adjust the gains while in flight, didn't get any good result to stop the wobbling.
To take of i have to give it more throttle than before and i notice its much less responsive, if i descend quick, giving it full throttle is not enough to compensate and stop it to touch the ground. Vertical climbing is much slower than before.
btw, I calibrated the Compass, set in the software the correct offset position of the GPS to the CG.
I'm new to hexas, maybe i'm missing something
I did test the GPS features though, even with it being so unstable. I set a switch in my Aurora 9 to force the failsafe. It worked perfectly, RTH landed about 4 meters from take of.
I want to test it a bit more before i try the GPS in my 450 quad, tomorrow i will do more tests, i didn't test IOC yet so i'll try it, and i'll try to make a video of it. I also have a F450 frame but i dont like it much, The Dji frames are cool, but have some issues with vibrations
If someone has some tips i'll appreciate it
