Pitch trim:
Set the trim slider for the pitch trimming (see figure 1, item 15) to the middle value. The helicopter should then hover
at a consistent height if the control stick for the pitch function is a little above the middle position. The pitch controller
(see figure 1, item 2) should be turned to the very right (100%).
