servo lag
I think I read about someone having the same problem, but I really cant find the thread.
I'm running 8611 on the elevators for the edge. Both linkages are set up identically, I've adjusted mid points to give a perpendicular servo arm. I've adjusted throws using end points to give identical up and down throws on both elevators.
But, there is a noticeable delay in one servo. I cant time it, but it is apparent.
I'm running one servo into one channel, and the other into another, so I know it is not an issue with a y lead.
Any thoughts?
Mike.

RE: servo lag
well, that could be your problem. i had the same problem on my edge. i had a 6 " extension on the cahnnel 7 servo, and it also lagged, but only during the range check. so for all my servos, instead of using extensions, i cut the servo leads and solder a new piece inbetween so it is one long lead coming from the servo. i do this for all my servos anytime i need an extension. the more connections you have, the more voltage you loose. and that long of a lead, it could loos a lot of voltage on the way to the servo. thats all i can think of, if any one else has any other ideas, please post em.

not sure why only one side would do it though, since they both have the extensions. futaba or JR?

RE: servo lag
um, is the 4.8 fully charged? 5 8611's may be draggin it way down, which could possibly be it, not too sure. what radio are you using? i cant think of any other reasons why it would be doin that.

RE: servo lag
I heard of this problem before hear on RCU with split ailerons. Someone said that it has to do with the bandwidth available to us. I will post a link if I come across the thread.
Sure enough, I notice it a slight bit on a plane I have, on the ailerons. I would assume the same situation happens with the elevators. But I could be wrong.

RE: servo lag
i remember the thread your talking about and the lag was in the radio it was a mid lvl futaba i think they where talking about 7 c 0r 9c something about the first channel being 1024 and the second channel being half that

RE: servo lag
yeah, it is only a small 4.8 volt battery, and they are all dgital servos, could be just not enouhg power form that little battery if it isnt fully charged to keep them all going 100 %

RE: servo lag
All radios will do this, some worse than others.
When you use 2 different channels for the elev./etc. the refresh/frame update rate is delayed between channels. The further the channels are apart the worse it seems to be. No way around this.
It will not affect how the models flies in real flight.
If you move the sticks slow you will not notice this, but when slammed from side to side 1 servo will lag slightly.
The only way around this is to use 1 channel for both. (I would not!!!!)
Or buy a new Futaba 14mz, I believe there refresh rate is so fast you will not see this.
