ADJUSTMENTS AND FLIGHT TECHNIQUES
TRIM
Trim Authority
When Trim adjustments are too sensitive (Ex:
One notch on the trim lever in either direction is
too much) the Trim Rate (Authority) can be
reduced, allowing finer adjustments.
ATL
This type of trim is most useful on the Throttle
channel. When the ATL function is used, the trim
lever will affect only the extreme LOW throttle
servo position. The servo position at HIGH throt-
tle is unaffected by the trim. Therefore, the idle
speed can be easily adjusted, while the full throt-
tle opening remains the same.
Cross Trims
Whether or not the Throttle (CH3) and Elevator
(CH2) trim levers are "crossed" can be selected.
Trim Memory
Trim settings can be memorized by the com-
puter, allowing the trim levers and knobs to be
returned to neutral position. The trim settings
can be left stored on the same program while
flying other models, and may also be copied to
other programs in the transmitter memory.
