I'd like to make a remote control LEGO car with steering and forward/back functionality.
Looking at the LEGO Power function parts I'm assuming I need the following:
- A battery (8881 or 8878)
- A motor for forward/back (8883, 888003, 7772)
- A servo for the steering (88004)
- A IR receiver (8884)
- A IR remote (8885)
- 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?
