He said the problem was still there with top deck loose indicating the issue is at chassis level. If your sure its not a thick screw head as I found, start loosening the bulkhead screws 1 at a time and carefully watch for a bent head or one that does not run true as your spinning it. From there loosen each bulkhead and check again for flatness to determine a possible bulkhead issue.

That is another good point, if you mounted the servo to the mounts outside the TC and dont have it flat then install...you have a problem. Also using washers on the servo screw heads will help from twisting the mount and causing tweak.
