CHAPTER 6: FUNCTIONS (SYSTEM MODE)

Helicopter
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 XP662 allows you to combine the hold and fail-
safe presets for all six 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 byyou. 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.
