d) Nod function
With the help of the nick function you can move the model helicopter forward and backward. The right control stick
(see ill. 1, pos. 4) is used for this as well. If the stick is moved forwards slightly, the swash plate will be tilted forward with
the aid of the nick servo and the model will fly forward. If you pull the stick towards the back, the model flies backwards.
