I just got a superx and installed it in a trooper Q700 in an x8 config. I'm currently running into some issues with vibrations/oscilaltions in fast forward flight. This is evident in the brushless gopro footage. I currently have the att gain set to 20% and i'm trying to dial it in by changing the basic gains in the app. I started at 1.2 and now i'm on .9. I'm not sure if the vibrations are from the wind hitting the camera during FFF. The gimbal is mounted on a clean plate and the 6s 8000 pack is mounted to an adjustable CG tube also on this clean plate. If you grab the battery and move it side to side, it does shift a bit and can see it causing the movements i'm seeing in the video. I'm hoping that dialing gains down further will reduce it.
Also, does anyone have an X8 coaxial log I can look at? the motor output seems weird.
Here's mine from yesterday:
http://log.xaircraft.com/report.htm#2014_09_18_190951.750_38.1.03.32
I'm running 13x5.5" on top and 12x6.5" on bottom.
Arm 1: M1=54%, M5=34%
Arm 2: M2=32%, M6=52%
Arm 3: M3=54%, M7=34%
Arm 4: M4=36%, M8=56%
It's weird that the top and bottom motors alternate roughly the same power outputs on each arm. I wonder if this is a coaxial thing or all 4 arms are out of alignment by the same amount. With the trooper, the motor mounts and tube is indexed for alignment. I feel like if the motors were out of alignment, the motor outputs wouldn't be that consistent per arm. Unless all the arms are off by the same amount.
Any thoughts or comments about my log?
Thanks
