Dave's comment below is why I fly ONLY JR equipment -- the good stuff!

</font><font face="Calibri" size=2 color="#1F497D">This will end up 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.<br>
<br>
It helps that being a little late to the dance afforded them the
opportunity to address those concerns. <br>
<br>
I don’t think it will be long before latency numbers are all low enough
that it won’t be a critical criteria, but for now it’s good to see all
the manufacturers taking note and making improvements with each new
release.<br>

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...<br>
