Bob Function
The bob function allows you to move your model helicopter forward and backward (see Fig. 13). Steering likewise
occurs with the right joystick (see also Fig. 1, Pos. 5).
If you push the stick forward slightly, the electronics in the quadrocopter change the propeller speeds such that the
model tilts slightly to the front and thus also flies forward.
If you steer backward on the transmitter, exactly the opposite speed changes of the propellers occur and the model
flies backward.
