I think what you should do is try with the default settings and then work your way up/down. 
you say your quad is uncontrollable on the roll axix.  What does your GCS show on graph regarding the roll.  Are they showing crazy readings.  May be your roll axis gyro is the culprit. Maybe.

Thanks dreamfly. I tried fiddling with the PID values for the roll axis. I started with P at a MIN vlaue and started working my way upwards (I heard P "fights motion"). No luck yet. And, I always used to fly with the ACC switched off (stable mode disabled). I figured that out only recently and enabled the safe mode. It flies the same way: uncontrollable and sluggish...
Thanks,
Vineet

normally you have to give both the picth and roll almost the same valuse.  If not then I believe that you have a faulty roll gyro.  I am telling this with the experience I had on my flight controller.
Does the GCS show proper reaction to your movements?  Why done you post a video.  it might be better to understand your problems

@dreamfly: Thank you. I believe the gyros are OK, for the movement of the quad is perfectly reflected in the GUI. I'll surely post a video when I'm done. Smiley

I'm afraid I didn't understand that. But most of them must be posting videos in their build-logs itself. Like:

Yes that's exactly what I needed to view the other members flying videos and builds.  Anyway we seem to have a small community in the multirotor category but growing for sure!

@Dharmik
I have a centerplate for a Tri and all the Aluminium tubes but not really finding the time to put them together.  I have to really manage my time and see if I can get one up in the air soon.  Too many activities happening these days and not really finding the time to fly.

Yes, I love warthox's videos, too. I follow his vimeo channel regularly. His "1.2KW MWC Quad" is a must watch.

Thanks,
Right now I'm building a lighter and more symmetric frame. My frame weighs 300g+ and is way out of symmetry. I think that should be causing the automatic drift and other problems. Smiley

oh yes. That's very important I think but on the other had when I look at some of the other quads with their symmetry seriously in question, I really begin to wonder how these quads really work Wink

What do you recommend as a central 'plate'? I used aluminium, but now I am building it with something similar to fiberglass. (the translucent examination pads).

Actually you can use anything that is regid to hold the frames in place without bending.  I use 3mm plywood but need to look at something better.  How's the fibreglass material to work with?  Plywood is quite easy to cut.  I used the services of a laser cutter.

here is the video of my Quad. My controller is very similar to Cirius Multi Wii but with more features like, Built in USB, and FETs put on free pins of the Atmel 328 and brought out to pins for LEDs relays etc.,  Built in Battery monitor and Buzzer etc.
I was trying the Altitude hold in front of my house.
At 1.24, 1.38,2.34,3.54,4.22,5.37 u can see me holding the Xmitter free. I was shooting with my crude capcam

Mr. Ashta,  This definately calls for a get-to-gather with you at try out your board.  I cannot view your video since I am at work and youtube is blocked.  Will view it this evening at home, But so far I am completely overwhelmed by your dedication to your hobby.  Anytime you are free, I would like to come and do some flying with you Sir!
