I. Trim Levers
• The trim levers associated with each control stick are used to correct (trim
out) the tracking of the aircraft.
• (Caution) Make sure the trims will move the surface past neutral when
moved to their extremes. This will assure you have adequate trim control
• During the initial test flight, note the positions of the control surfaces that
required trim.
• Next, center the trims and turn the receiver off. Now adjust the control
linkage on the plane so the surfaces are in the same position before the
trim levers are re-centered.
• Turn on the radio and receiver and recheck the control surfaces to ensure
that all the corrections were applied in the proper direction.
