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.

Q. What port in the receiver do I plug my HFX into?
A. The HFX always plugs into the throttle channel, typically CH #2 for a two-channel radio and CH#3 for a 4 or more channel radio.

Q. What is B.E.C.?
A. B.E.C. stands for Battery Eliminator Circuitry. This means that the speed control supplies power to the radio from the main power battery, so there is no need for a separate battery pack for the receiver.

Q. Is the HFX reversible?
A. No, the HFX is a forward only "Race Type" speed control designed for high performance. If you want reverse then you will want to get the HFX-R.

Q. What is the motor limit on the HFX?
A. We recommend no lower than 10 turns but if properly geared the HFX has no motor limit. Be aware that the lower the turns, the hotter the speed control will get and it may go into thermal shut off. If this happens you will need to gear down or go with a milder motor. Always make sure there is sufficient airflow over the heat sinks to help keep it cool.

Q. What is current limiting and why do I need it?
A. Current limiting limits the amperage that the motor can pull, the lower the setting the less acceleration you have but it will also increase your runtime. In situations where traction is limited the current limiter can actually act as "Traction Control" thus making the car easier to drive.
