The Trim Offset Memory Function of your XP652
allows you to test fly your aircraft and correct for
any built-in trim requirements. After you adjust the
aileron, elevator and/or rudder trim levers during
the test flights, the trim levers are no longer in their
center, or neutral, positions. The use of trim offset
allows you to return the trims to their center, or
neutral, positions without readjusting the control
surface linkages mechanically.
This function is very useful when switching from model
to model. It allows your trims to remain in their
neutral positions while retaining their corrections.
Using this feature, you can easily switch among the
five (5) model memories without the need to readjust
for each aircraft’s individual trim requirements.
Note:
In helicopter mode, the trim offset memory
values stored will alter the servo position in both
normal and stunt modes. Separate adjustments each
mode is not possible, except through the stunt trim
function (page 83).
1. First, test fly your aircraft and adjust the aileron,
elevator and/or rudder trim levers. After all
adjustments have been made, land your
helicopter. DO NOT adjust/reposition any of the
trim levers at this time.
CAUTION: Do not attempt to adjust the Trim Offset
Memory Function while your model’s engine is
running. Please stop your aircraft’s engine before
entering the Function Mode.
2. Turn on the transmitter.
3. Press the MODE and CHANNEL buttons
simultaneously to enter the Function Mode.
4. Press the MODE button until TRM offset appears
on the screen.
