OK guys, here's the skinny on Horizon. You have to return the radio, they will NOT sell parts...not even an antenna on any Spektrum product. Eric....sorry guy...I sold my DX7 off just before you smoked your screen. You can check this fourm marketplace OR E-Bay to find units that are not working. Right now they have a DX6 listed that the throttle gimbal is inoperative....just an idea.
