Adjustable travel limit (ATL): makes the channel 3 TRIM LEVER (THROTTLE TRIM) effective only at low throttle, disabling the trim
at high throttle. This prevents pushrod jamming due to idling trim changes. This function defaults to ON. If you are not using
channel 3 for throttle, you may want trim operation the same as on all other channels. To do so, set ATL to OFF.
If you need the ATL to be effective at the top of the stick instead of the bottom, reverse the THR-REV setting. Note that this
affects all models in the radio, not just the model you are currently editing. See servo REVERSE, p. 31.
GOAL of EXAMPLE: STEPS: INPUTS:
Servo reversing (REVERSE): changes the direction an individual servo responds to a CONTROL STICK motion. [Since channel 9 is
switch only (and only available with a PCM receiver), its servo REVERSE is in the AUX-CH control screen with its switch assignment.
See p. 39.] For CCPM helicopters, be sure to read the section on SWASH AFR (p. 79) before reversing any servos.
Except with CCPM helicopters, always complete your servo reversing prior to any
other programming. If you use pre-built ACRO/GLID functions that control multiple
servos, such as FLAPERON or V-TAIL, it may be confusing to tell whether the servo needs
to be reversed or a setting in the function needs to be reversed. See the instructions for
each specialized function for further details.
Always check servo direction prior to ever
y flight as an additional precaution to confirm proper model memory,
hook ups, and radio function.
NOTE: THR-REV is a special function that reverses the entire throttle control, including moving the trim functionality to the
Stick’s upper half. To use THR-REV, turn off the transmitter, hold down the MODE and END keys, turn on. CURSOR DOWN to
THR-REV and turn the DIAL to REV. Turn the transmitter off and back on. This change affects all models in the radio.
