One of the easiest things you can do anytime you are having trouble, is to plug one of the servo leads (either rudder or elevator) into the channel that you are using for the LED Controller. PLEASE MAKE SURE NOT TO PLUG THE ESC INTO THIS CHANNEL.
The servo should move according to the input from the transmitter. If it doesn’t follow your radio inputs, then there is a problem with your transmitter programming.
If the servo does move correctly, according to your radio inputs, then the next test would be to use a servo tester connected to the LED Controllers CH1 input. With the servo tester powered up, the knob on the servo tester should control the LED patterns on the plane. If it doesn’t, double check the connectors for the LED strings that are plugged into the LED Controller. The signal wires should be connected to the pins that are farthest away from the board.
I plugged in my LED Controller, but the LEDs don’t light up.
The most likely cause of this, where absolutely no LEDs light up, would be if the cable from the receiver to the LED Controller is flipped. Make sure the signal wire is connected to the pin farthest away from the board, on both the input pins and the pins connecting to the LED strings in the plane.
I plugged in my LED Controller, but the LEDs all just blink red.
Any time that all the LEDs constantly blink red, it indicates that the LED Controller does not see a signal from the receiver on either of the input pins. This can happen if there is a bad connection or broken wire in the interconnect cable from the receiver, or if the transmitter/receiver is not programmed correctly. Keep in mind, the BNF (bind and fly) version of the FT Night Radian comes from the factory with channels 4 and 6 not assigned to any channel in the receiver. You will need to get the programming cable in order to unlock these channels for use. If you google "as3x programming cable" you will find links to buy the cable, as well as articles and blogs from people who have done it. See our FAQ page for more information on this.
Another cause of the LEDs all blinking red is if the Controller Board was damaged during installation. If the cable from the receiver is not plugged into the CH1 or CH2 input correctly, the unit can get damaged. Make sure the pins are all lined up correctly before powering the unit up:
If this happens, and you have verified that it’s not a configuration issue with the radio, I can send you a replacement board for $15, which covers shipping the new board and repairing the damaged board once it’s been returned. Shipping costs for returning the old board are your responsibility. There is a link on the Products page to purchase this repair service.
