XP652 MANUAL Airplane
The Hold Function is automatically activated when
the radio is turned ON and in the S-PCM modulation.
This function stops (or holds) the servos in the
positions they were in just prior to the interference.
Therefore, your aircraft maintains the position held
immediately before the interference was experienced.
When a clear signal is restored, the Hold Function
releases, and control of the airplane returns to you.
The XP652 allows you to combine the hold and fail-safe
presets for all six (6) channels on the receiver you can
select fail-safe or hold independently for all channels
on your aircraft. In other words, some channels will
hold their last clear signal position, while others
assume the preset position. Once the fail-safe has
been activated by signal interruption (interference), the
transmitter automatically moves the servos to a preset
position. The predetermined servo positions are set by
you. In the S-PCM fail-safe, the time delay (the amount
of time it takes, starting the moment the interference
occurs, until the servos assume the preset positions) is
fixed at .3, or 1/3, second.
After the interference has ceased, normal operation of
the airplane returns to you immediately.
