14. Checking the steering and driving functions
Now connect the servos or speed controllers used in your model and the power supply to the receiver.
For a better understanding, the steering function is demonstrated using the example of a model car. To
prevent the model from unintentionally starting when checking the control and driving functions, place the
model with the chassis on a suitable base (wooden block or similar). The wheels should be able to turn
freely.
a) Checking and setting the steering function
Turn on the transmitter and, if you have not already done so, set the trim in the centre position for the drive and steer-
ing functions according to the instructions in Chapter 13.
Then switch on the receiver. If you have connected and mounted everything correctly, the steering of the model should
react to the rotary movements of the steering wheel (see Figure 1, Pos. 2).
When the steering wheel is in the centre position, the wheels should be straight. If the wheels are at an angle even
though the steering wheel is in the centre position, check the correct position of the lever on the steering servo. The
steering linkage rods can be readjusted, if necessary.
If you steer the steering wheel to the left on the transmitter, the wheels on the vehicle should turn to the left (see Figure
11, Sketch A). If you turn to the right, the wheels should turn to the right (see Figure 11, Sketch B).

Warning!
The operation of the steering wheel on the transmitter requires only slight force. Therefore, it is absolutely
sufficient if you operate the steering wheel only with your fingertips. Attempting to turn the steering wheel
with increased force when reaching the end stop can lead to the destruction of the steering mechanism in
the transmitter.
