I installed an Itelite antennae mod today on my P2V+ V3. Everything seemed to go smoothly. When I went for a test flight I was pleasantly surprised to see 2200ft where in the past I would lose signal around 1000ft. But I have no control over the movement of the camera. I am able to take pictures and video but I'm not able to control up/down. Does anyone have any ideas? Thanks in advance.
