TheSequencermenuoptionprovidesthis-then-thatmixingwitha
timedelay.Fivedifferentsequences(S1throughS5)areavailable
tocontrol2functionseach(AandB),in2timingdirections(for-
wardorreverse).Sequencesappearthroughoutfunctionscreens
as assignable switches.
CAUTION: Always review the action of a sequence on the
MonitororX-PlusMonitorscreenBEFOREoperatingthe
model to ensure controls act as desired. Failure to do so
could cause a crash, resulting in property damage and or injury.
You can program multiple functions to sequentially activate in
responsetoanassignedswitch.Forexample,anassignedGear
switch can open gear doors, lower the gear, then close the doors.
In reverse, gear doors open, the gear retracts and the gear doors
close.
You can assign each Sequencer function to a switch in most
FunctionscreenssuchasFlightMode,DualRate,Mixing,Throttle
Curve,PitchCurve,etc.
You can assign several functions to a sequence to decrease
thenumberofcontrolsyouneedtotouchduringcomplexight
transitions—forexample,applyingyourassigneddualratesand
exponentialwhenthelandinggeardeploysandtheightmode
changes.
IfyouselectanS-Number-Asequence(e.g.S3A),thesequence
operatesasatimed5-positionswitch.AnS-Number-Bsequence
operatesasatimed3-positionswitch.The5positionscorrespond
to the sequencer values shown on the time delay graph in the
second Sequencer screen. In a function screen, highlight each
point(0–4)andselecttheswitchpositiondesiredforafunctionto
be active.
WhenS1B(oranothersequence-number-B)isselectedasa
switch in a function, the sequence will operate as a timed 3-posi-
tionswitch.The3positionsactas‘kickpoints’ofthemovement

Sequencer Set Up
1.IntherstSequencerscreen,select1ofthe5available
sequences.
2. In the second Sequencer screen, assign a switch to the
sequence. We recommend using a 2-position switch.
Tip: If you need to use a 3-position switch, you must assign
one direction to two adjacent switch positions—e.g., 0 and 1.
Assign the opposite direction to the third switch position.
3. Assign the timing for the Forward and Reverse directions as
desired. There is no delay when you use the Nor option. You
may also select a delay time between 0 and 30 seconds.
4. Assign names for each sequencer function as desired.
5.SelecteitherStep (S) or Proportional (P) for the Sequencer
output.
Step: The sequence only changes at kick points. Otherwise,
thereisadelayinthesequenceuntilitreachesthenextkick
point.
Proportional: The sequence movement is proportional be-
tween kick points. The sequence maintains rate and direction
untilitreachesthenextkickpoint.
6. Adjust the Sequencer motion percentages in the third screen.
Forexample,youmaymovepoints1,2and3closertothebegin-
ning of the sequence so the motion occurs earlier. This results in a
delay between point 3 and point 4 at the end of the sequence.
Testing the Sequence
The Sequencer function determines the response for channels
included in the sequence.
Refer to the Monitor screen to see how respective channels
interact in the Sequencer.
