Q. How do I set up the HFX?
A. First, turn on your transmitter and make sure the throttle trim is set to neutral and your throttle EPA (if you have it is at 100%. Next, while pushing the set up button, turn on the switch. Wait for the red light to blink, and then pull the trigger to full throttle. Wait for the light to blink again and push out on the throttle for full brakes. Wait for the light to blink again, and then let off to neutral. You're done! You should have full control at this point. However, if the light is blinking, then a mistake was made and you will need to repeat the process.
