Motorized Technic-style builds: motors, remotes and gearing
Add a motor and a model drives itself. These guides cover the battery box and switch, which motor to choose, how to gear a motor for speed or pulling power, servo steering, two-motor skid steering and IR remote channels. Every guide links free motorized builds with step-by-step instructions.
