Andrew, hope its not a fault but to me it sounds like a calibration error as the light is only supposed to flash if the input signal is out of range. Set your trims on you transmitter to the middle, power up the receiver first (if not using the BEC), then the scorpion (with the calibrate jumper already in place) and move all your sticks to thier full extents several times then return back to the middle and power down the scorption, then recevier. Finally remove the calibration jumper and test it again. Hope that works. Could you also tell me what type of receiver you are using?
