[NSRCA-discussion] curious

[Andrew Jesky]

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.

Figures I'd end up with a more complicated one to learn on.  I have an Escape as my first F3J plane and it's a 6 servo wing.

At the end of the day I'd be curious to know if anyone can really "feel" the difference that is being discussed here on any of the radio systems.   Slow latency is one thing, but this channel group delay is extremely small...hard for me to believe it's noticeable for 99.9999% of uses, and of the remaining 1 in a million use cases, how many people have the skill to detect it?

Hey Bill,

I wasn't referring to multiple servos on a single control (2 elevator servos, etc) as much as mixing them to function together.  So for example when you want to reflex the trailing edge of your glider wing, you need your inner and outer Ailerons and Flaps to all move in unison.  That's going to be hard to do with the 14mz if you're asking 6 servos to move exactly together because of the way it sends the signal in groups.

Actually it is no issue at all with the 14MZ, at least not that I have noticed on any of the 7 or 8 thermal duration/F3J gliders that I have used it in. Keep in mind that 6-servo wings are rather uncommon. The most common set up uses 4 servos, one aileron and one flap per wing half.
