Important
: Move the flap switch to the rearward position. Adjust
the FL. Travel adjust to 0%. Reposition the servo arm so that the
ailerons are neutral. If necessary, readjust the aileron sub trims
slightly.
Note
: To get the most performance out of your Ultra Stick™ Lite,
long servo arms (1 inch) like JRPA215 are
recommended. This provides for large control throws, allowing
for more aggressive maneuvers. To achieve the control throws
listed below, long servo arms may be necessary.
Note:
Use the Dual Rate function to achieve these throws (see
page 52).
