Flashing orange lights on the DMD indicate no control signal is incoming from the receiver. Specifically, the rudder channel. I'd suggest checking your bind between the radio and rx with a separate rx battery and servo. Remove the rx, rebind, and connect the battery to the battery terminal. Plug in the servo to 1 channel at a time and verify it works. Then, once you have it where you know it will run, add it back into the tank system and connect it to the DMD.
