Thanks for that Lee I will spray a little polish on the belt and move the rx to see what happens.I was thinking about static from the belt causing the brown out. Try spraying some silicon lubricant on the belt and or you can ground the tail boom to the frame. I would be careful with that placement as it looks from the picture as if the antenna could get caught in the main gear. I had mine sitting in the frame with the antennas towards the back sticking out to the side.
