h) Trimming the Helicopter
Push the pitch stick (see figure 1, item 12) from the bottom position (engine off) carefully forward and observe the
response of your model. Shortly before the helicopter starts hovering, you can already determine in which direction
your model wants to move.
If the helicopter wants to turn to the right with the tip of the fuselage, then reduce the speed and push the trim slider for
the tail function (see figure 1, item 11) gradually to the left. Push the pitch lever carefully forward and check if the
adjustment was sufficient. Keep repeating this procedure until the helicopter no longer has any tendency to turn to the
right. If the nose of the fuselage turns to the left, carry out a right trim adjustment.
Figure 11
If the helicopter wants to turn or tilt sideways to the right, reduce the speed and push the trim slider for the roll function
(see figure 1, item 3) gradually to the left. 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 to the right. If the helicopter wants
to drift sideways to the left, carry out a trim adjustment to the right.
