Re: Lagging Servo?
The following is what I've been told:
The radio system refreshes the servo positions in sequence. Not positive about JR but I heard futaba used to do all odds then all even channels?
Example
(1-3-5-7-9-2-4-6-8) (1-3-5-7-9-2-4-6-8) (1-3-5-7-9-2-4-6-8)
So if you had for example one servo on 1 and the other on 6 you've got a good bit of lag between those. Having one or both reversed can make the situation worse. Keep in mind this was most noticed in the 9c etc which already had 140ms of latency. The elevator matching was ugly sometimes.
Both manufacturers now have servo grouping which I believe assigns similar servos to adjacent positions in the refresh sequence so Ailerons will be 1-2-3-4 etc. They might even update simultaneously not positive. Ideally the problem should be all fixed now, or at least as much as the radio manufacturers can do.
Having said all that I did not notice any problems setting up my Extra. I use a 9303 and 7955's and I took a LOT of time to make sure it was right. Hours of matching deflections and I did not find any lagging.
Things I'd suggest trying:
-try a different power system on the bench and see if you can remove the issue. Those cells may not be putting out as much power as you think
-check your extensions. Are they heavy gauge? What about those connectors?
-if you plug two servos directly into the receiver with no extensions or linkages is it still lagging?
