I might be in the minority, but latency was most certainly an issue with
some of the early PCM radios (which were SLOW, compared to a good FM set).

 

So far as the latency in recent times, it was noticeable with early 2.4
sets..and even some relatively modern sets I find difficult to fly because
of the variation in latency (differential between minimum response time and
maximum response time).  Most of the modern radios are fast enough that the
latency is not an issue, and whatever latency there is can be pretty easily
adjusted too, if it is consistent.

I'm with you on this one Mark, I could notice the latency a little bit in
some systems but the servo grouping is nothing that I can tell. I think the
guys that really see this are the heli guys. I have talked to many of them
and they do tend to tell me they can "feel" the difference. They are using
much more servo throw all the time between positive and negative collective
as well as cyclic.

Andrew is right, this all got started with the heli guys who flew CCPM. On a
big plane grouping is noce just to minimize servo stress and current draw,
but it is not something you are going to feel while flying. And in a glider
the only thing I ever work hard on matching is that the flap throw is
matched through the entire range of movement.

Like I said, a couple of years ago nobody even heard of latency, now it is
