Trim System

The Trim System Code 83 allows the adjustment of the trim
authority and also allows the flap trim and aux trim levers to
be turned on or off. An LST function when turned on causes
the aileron, elevator and rudder trim levers to only affect the
center and not affect the endpoints, which is desired for aircraft
to prevent over-driving the servos when trim is used. For most
40% aerobatic aircraft it is recommended to turn the flap trim

and aux trim off. The remaining settings are recommended
to be left at the default settings, 100% throttle, 4 for Aileron,
Elevator, and Rudder, and leave LST turned on. Once the aircraft
is trimmed using the default settings, the trim rate for Aileron,
Elevator, and Rudder can be reduced to 1 to allow for fine
adjustments of trim to perfectly trim the aircraft in flight.
Note: If a large amount of trim is required for the model,
LST trims will reduce the amount of throw in the direction
of the trim, and reduce control effectiveness in that
direction.
