Can i have the option file of the quad in this video ?


Do i need a gyro on the rudder channel ? 
Because when i rotate the quad on the quad monitor it looks like it trys to compansate.

You dont need an external gyro on the rudder channel.  We are compensating with one of the internal gyros.  I had very good results with the yaw after adding compensation.
 
The option file you downloaded is the one I used.  Make sure you change the board type.
 
I believe you are the first flyer to try the quad software.  Please let us know how well it works out.  Comments and suggestions are welcome.
 
There should be no problem changing the baud rate to 4800.
 
If you have any other questions, let me know,
 
Jerry

One thing I forgot to mention that may help.  If you follow the readme it really walks you through what you should see on the Quad Monitor.  If you haven't changed the board type, that would produce unwanted results.  Maybe you can tell me what problems you are seeing.
 
Later,

I have changed the board type to INVENSENSE_BOARD and modifyed the 
ConfigJerrysIXZ500.h file to the values i have in the ConfigIXZ500RAD2a.h file because i have the doughter rusty board  (i have used it before in an airplane with great success)

Yesterday i have connected the FTDI and veryfied the directrion of the compensation etc... that when i saw that yaw axis is also stabilized and had thoughts that maybe external gyro is not needed.


It looks like the problem is in roll axis only i will try make a movie showing the problem  and my configuration.

I have made some test without props and X GYRO wave forms shows much more noise the the Y GYRO
I tryed to rotate the UDB 90deg and see any chage in the second image quad_rotated.jpg was , i also removed the prop savers .

Is the noise difrence critical ?

So are you saying this is with no props and prop savers and the motors running at 50%?  I see the throttle at 50% and the ESC are enabled in the second jpg.

The attached picture is my quad with no props or prop adapters, and all 4 motors running at 50% throttle.  Your noise level is even better than mine from the X Gyro.  The X Gyro is picking up more of the vibration from the motors in the X axis compared to the other two gyros.
 
Which motors are you running on your quad?
 
I dont think the noise difference is a problem.  I would say if it passed all the other tests in the setup doc, you should be ready to fly.
 
Keep me updated with your progress,

 
Jerry

The second image is with prop savers and half throttel ,520-550 in the time axis of the graphs.
The first image is  50-80 .
