<font size=3>Why would it not work to put 4 aileron servos in one group,
and 2 spoileron servos in another group? I can't imagine that a
very slight delay between ailerons and "flaps" would
matter...<br><br>

<blockquote type=cite class=cite cite="">So going back to my first
sentence/example with 6 aileron servos, I would want three each in one of
the three groups of four--in this case--2-4 and 5-7. Any potential
latency 'lag' would have to be compensated with servo speed, end point
and sub-trim? But probably in reality, not really noticeable.
In my mind, I am/was confusing 'grouping' and 'mixing' on how grouping
works in the radio. Thanks for the clarification.<br>

Honestly, you've lost me. On the PPM/PCM 14MZ if you plugged 6 servos in
and they were all assigned to aileron the servos plugged into channels 1,
2, 3 would act together, and the servos plugged into channels 4,5,6 would
act together. Acting together here means with little or not noticeable
latency.<br><br>
The pre 2.4 14MZ grouped channels into 4 groups of three channels. The
2.4 14MZ makes three groups of 4 channels. It is built into the radio.
Plugging a servo into channel one and telling the radio that is aileron
and then plugging another servo in to channel 12 and telling the radio
that this is also aileron will result in a potential lag for the last
servo compared to the first servo. The radio is not going to set up some
sort of Master-slave servo/channel mix.<br><br>
Again, channels 1,2,3,4 are in one group. <br>
Channels 5,6,7,8 are in a second group<br>
Channels 9,10,11,12 are in a third group.<br><br>
The signal will get to the servos within each of those three groups at
essentially the same time. WHat is plugged into those channels and what
function you have assigned those channels is irrelevant from the
standpoint of the radio.<br><br>
So say you had 4 aileron servos, 2 per wing. You plug the left wing servo
into channels 1 and 9. You plug the right wing's servos into channel 2
and 10. The two servos on either aileron will not be in synch as far as
time that they receive a signal so there may be a potential latency
issue. In other words, the servos may "fight" each
other.<br><br>
Channel one is not going to "say" to channel 9 "hey I am
in charge and take your lead from me" as far as the timing of the
receipt of the signal to move. They will act together in the sense that
they will move in response to the aileron command and in the same
direction.<br><br>

<dd>So if I plug say 6 ailerons in to channels 1-6 like the original
Futaba MZ web main page shows, we would have to compensate somehow with
End Point Adjustment and Servo Speed on two? That doesn't seem
right. It would seem more logical that in a non-grouped
setting--but effectively grouped--like ailerons, twin elevator halves, or
flaps, you would want them in the 1-4, 5-8, etc. groups--but if you are
specifically 'telling' those servos "Pal, you are tied to this guy
and he's the boss--you do what he does."...wouldn't the 'grouping'
function operate that way?<br>
