Left bank slight dive - Talon

Something is wrong with my Talon, it is starting to drive me crazy. It banks to the left with a slight dive and I can't fidure out why it is doing this. All control surfaces are level and the only thing I have on the left wing is a Dragonlink dipole antenna. I don't think the weight of the antenna + coaxial cable that runs 2/3 of the length of the left is causing this.
