Hi, sorry to hear about the issues with your CC3D… by the sounds of it there is nothing actualy wrong with the board but rather just a setting issue. I am fairly sure that your servos are just reversed.
My suggestion would be reinstall the firmware and run through the setup wizard as towards the end of the wizard there is section that allows you to check the control sufraces on your aircraft and reverse them if needed.
Changing the Orientation on CC3D
However if you think your orientation might be wrong, here is a table showing you what you need to change. (thank to Sam for the image)
Once you have decided on your orientation then just change the appropriate settings on the openpilot GCS on the attitude tab.
Hope that helps!
