If the helicopter wants to drift forward, then reduce the speed and push the trim slider for the nod function (see figure
1, item 7) gradually backward. If you dismantled the Nick/Pitch stick function at your transmitter, then you must adjust
the opposite steering trim (see figure 1, item 9). Push the pitch lever carefully forward and check if the adjustment was
sufficient. Repeat the procedure until the model does not show any tendency to drift forward. If the helicopter wants to
drift backward, carry out a trim adjustment forward.

Later you can adjust the steering trim for the Pitch function so that the Pitch control stick remains in the centre position
when the helicopter hovers.
If the control paths of the steering trim are not quite adequate for an optimum correction, you have the possibility to
change the control of the lower rotor blades mechanically. For further information, refer to the chapter "Fine-tuning the
model helicopter".
