Just seems like im running into more trouble with this gimbal. After I installed the 7th channel wire and the lever on my transmitter I tried powering the gimbal up and now it stabilizes to an off center angle. No matter where I position the gopro it always resorts to being skewed and crooked. This leads to manual tilt also being skewed and even oscillating if I tilt too quickly. Here's a video demonstrating the problem. Any help?

Seems a lot of people are experiencing some kind of roll when they attach the pitch wire. (just to be sure,. did you leave the roll wire disconnected, or did you connect it to the Naza? definitely leave it disconnected just in case).
What you need to do to try to remedy this is to run tje CALIB_ACC in the software..
connect the gimbal up to your windows computer (using your gopro usb cable or similar), install the setup software,. make sure you're running a current version of java,.and then run the ARRIS GUI app.
you click on Com8 (or one of the Com's on the left side of the screen, hit Read,. then the gimbal should come to life and show you all the settings.

To calibrate accelerometer, you don't need to connect main power. Just connect FTDI cable.
Simple mode: level the sensor board strictly horizontally (this is “base position”), fix it in this position by hands, and press CALIB_ACC button (or menu button). Signal LED will flash about 2-3 seconds. Don't move sensor board while calibrating.
(I havnen't tried the following , but it's in the SimpleBCG manual):
Extended mode (preferred): first of all, make calibration in simple mode. Then, rotate sensor board by 90 degree, to make every of 5 faces “looking up” (total 5 positions excluding “base”). Fix sensor in every position, press CALIBRATE_ACC and wait about 3 second. Repeat this step 5 times (the sequence of rotation is no matter). Remember, that calibration in simple mode will cancel results of extended calibration, so make it first.
Hint: Precise ACC calibration is very important to keep horizon stable in case of aggressive flight
