being somewhat of a shameless plug, but when we were involved in discussing
features of the new Airtronics radio (SD-10G), this issues of grouping channels
was a BIG deal to the glider guys. They often have 6 and 8 servos in
their wing alone, and having a small delay between some of the channels
updating creates trimming issues such that they would not be able to take
advantage of using separate channels if there were delays. Having such a
strong presence in the glider community, they needed to address it. The
result is that the new radio updates all 10 channels simultaneously rather than
in groups of 4. NO clue how that was pulled off technically (or how
they got their speed so high) but both are clearly a result of these types of
“threads” and the resulting priority that they’ve placed on
latency concerns.<o:p></o:p></span></font></p>

The original post was in '05 in that link. He has been updating it as he
gets new info. It's worth a read--but takes a while. Some feel the
thread has contributed greatly to latency being decreased in radios across the
board. As someone pointed out "..radios got pretty damn fast pretty
damn fast..."<br>
Regarding Futaba modules--at least on the TM14, the information is sent in
groups of four, so you would have minimum latency difference for example
between channels 1-4, 5-8, 9-12, etc.. so it would be better to have dual
elevators next to one another and possibly ailerons in one of the 1-4 groups if
your transmitter has the capability to reassign channel positions. It
would also be helpful to those that have more than one servo per surface.
It's very important to the helo guys as they need the swash plate to move
evenly. Apparently not quite as noticeable in pattern.<br>
I switched from 50mhz/5114DPS to the 2.4/TM14/6008HS combo and the best
one word description I can give is "silky"--but it could be
additional latency--Futaba says there should be no difference. I think I
like it--but I have to--it's what I've got! <br>

PS Anyone need any DPS5114s on 50mhz.?..yeah, that's what I thought...<o:p></o:p></span></font></p>
