Got a few flights on my X8 with SuperX. (I have a small lead bar strapped to the gimbal to simulate the weight of the camera.
Flew great. used 1.2 across the board and .9 for height.
Might drop it to 1.1 we will see.
Rig flew awesome though. No complaints!
Steve, is that one of Beresfords frames?

Bottom half is. Top is Vulcan.
I have my Evo Hex and this X8 set up with the same Quick release. So either can carry my M5 or my Evo 3 Axis gimbal. Or vise versa.

Friends if you get a chance check this question I asked about dual versus single batteries: http://www.multirotorforums.com/showthread.php?21505-Two-5-000-6S-or-one-10-000&p=178844#post178844
Hi guys,
I have an Octo with the Super X controller that flies ok in calm conditions, but is very unstable in windy conditions compared to my other Octo which has a Wookong M for guidance. The Super X Octo has Ovroto 3520 400kv motors and Hobbywing 60amp Platinium ESCs. The ESCs do NOT have Simon K firmware and the timing is set to low. I have two dead weights that attach to the bottom of the Octo for testing, one weighing 5 pounds which I use APC 14x5.5 MR props and a 10 pound weight with APC 16x5.5 MR props. With either set up I can run the both of the flight control gains wide open and although I get some obvious shaking with the gains that high when I try to fly around or when the wind is blowing it still does not make the machine any more stable. Is there something that I am missing?
Thanks,
Wayne Mann

What do you mean by flight control gains wide open? Are they turned all the way up in the GUI? Or the gain knob???

In my experience, if you have gains all set to full that bird should be shaking like crazy. I've never gotten mine above 1.3. Sorry, maybe someone else will chime in, or post this in the main superx thread.

I've been testing gains and so far 1.3 to 1.4 works best. I have 15" props coming today and wanted to see how high i could go. Wayne , same boat here with rigidity ....bird doesn't get crazy on either end of the gain settings. My logs at 1.9 and 1.5 pitch and roll, height and yaw 1.0.

fltundra I looked at your logs. Nice for me to have a frame of reference. Are you satisfied with your vibe levels? Mine are comparable it would seem, and my video quality seems good at this time (other than my gimbal is rolling a few degrees).

My superx has just been moved to my most rigid frame to date (Vulcan) - but I would not have considered the last frame a rubber band either 
. Although that was an H frame style - so the vibes could have been caused by that.
The tarot 680pro I had it on at one point probably could be considered "rubber bandish" and that certainly suffered from the higher gains. That frame has too much flex.
If the gains are NOT making it shake, I would think it's probably less desirable, because it would indicate less tuning capabilities for the given frame. I think iI'd rather be able to hit too far and back off, then not know whether I had enough usable gain.

No not really because it fly's locked in at about 1.4 but jitters in fast flight and has vibes from frame in the video from my gimbal in anything more then calm wind. Video is best at 1.2, and at 1.9 you can really start to see the jitters, but know where near uncontrollable. I can strap my birds landing gear down and run up to about 97% in manual mode and not see vibes in the log any higher then .1. After many hours of testing I know most are induced in flight. Seems to be a very fine line on the gain settings depending on CG, motor alignment, and prop balance mostly.
