Lego Technic Power Functions controller steering MOD
The standard Power Functions IR Remote Controller has two buttons which are aligned vertically, one of them can be used this way to control the drive of a remote-controlled car, but for the steering, this setup is not intuitive nor practical.
This simple MOC adds a steering wheel on the right button to allow a much better control of RC cars, providing an easier and better play experience.
This is the setup I use to control my Lego RC cars.
