Servo and servo horn
The parts supplied with this stage are one of your model’s two servos, and a servo
horn. Both servos are the same. When fixed to the chassis plate, one will operate
both the throttle and the brake, and the other one the steering.
You cannot yet fit the servo, so these two pages will provide you with some details
about servos and how they work. This information will be useful if you have any
problems with a servo when it’s in use.
