I'd like to make a remote control car with steering and forward/back functionality.

Looking at the LEGO Power Functions parts I'm assuming I need the following:

  1. A battery box (8881 or 8878)
  2. A motor for drive (8883, 888003, 7772)
  3. A servo for the steering (88004)
  4. A IR receiver (8884)
  5. A IR remote (8885)
  6. Some Extension Cables? (8871, 8886)

But I'm not sure how the IR remote is configured to control the motor/servo or whether I need an IR receiver (8884) per motor/servo, or whether I'm missing another part.

What Power Functions parts do I need to make a LEGO remote control car?

  • The servo is not mandatory, you can use a standard motor with elastics for the steering: youtube.com/watch?v=jQ5ug1CwRa8 (warning: aggressive music)

Your assumptions appear to be mostly correct. Just for clarity, these are the minimum parts required:

  1. A battery box
  2. A motor for driving
  3. A motor for steering (unless you want to try a steer-on-reverse single motor design)
  4. An IR receiver (these can support two motors each)
  5. An IR remote

Extension cables and/or lights are optional depending on the design of your vehicle.
