QAV400 with Gimbal and HK Quanum Alexmos Controller

[MrBen]

This video was on stock settings and pretty good! I got some jitters when throwing hard left and right at about the 1 min mark however I have since set it up with some new settings I found online and its pretty much perfect now.

them flipflops are mental , more more

Did the tarot gimbal you got come from hk and did it come with summat to go in back port to give live out access and charging as manual refers to

[MrBen]

No it didnt Martin

here is another QAV400G video this time you can see it needs tuning still

QAV400 With Gimbal

PIDs too high, and I think a motor direction needed inverting too

[MrBen]

Just ordered one of these so I can be sure Im doing the 6 point calibration properly

Don't get the one with cheap bubbles in

Ben If that works let me know!!!!

A couple of other things I found:

During fast YAW rotating, camera deflects by ROLL, and then slowly gets to horizon
   

-Bad accelerometer calibration
-Sensor is not in parallel with motor
   

-Make advanced ACC calibration by 6 positions to horizon.
-Align sensor with motor axes

yeah Im not convinced my calibration was the best, having short wires from the GC to the IMU doesnt help me. I think with the camera pitched down it exaggerates it too, if you check at the end of the vid when it was looking straight out and I stopped every 90deg on yaw the horizon was acceptable.

Im gonna order a new one, think ill go for the DYS with a genuine Alexmos....

[Smit80]

Here you go Ben, this is my footage from Wednesday. My horizon drift is worse than yours I think..

It didnt look too bad tbh, couple of times when you faced west you could see it but overall not too shabby, 3 axis FTW isnt it looks very smooth, would like to see what your is like in FFF, I was reading on the QAV400 thread of fpvlab today they were going on about the dys 3 axis needing that 32bit controller 

[Smit80]

Ben, we need to try:

Follow Mode TAB
Follow for ROLL axis may be permanently enabled to disable completely, set "ROLL start"=90, "ROLL mix"=0
