Servo match.

[flypaper 2]

Does anyone remember the name of the electronic device that enables two elevator servos conected to a harness and be able to match one another.?

or matchbox

Any idea who the manufacturer is? Needs to be replaced as, when you give elevator control all the servos including the ail. start jittering. Had been working OK before.
Thanks for your help mpope 1. I googled matchbox and it came up made by JR . Not what's in the Chipmunk but will work better.

I used a simple y-adapter, and placed one of the two servos upside down on the mounting rails.

That's the way I do it too but a fellow flier bought this plane used with this device in it . It looks like a Y connector with this electronic chip about 1/2 in long at the joint. Flew once for half a flight when things took a dump. He managed to get it down in one piece. I'll install a normal Y connector in it for him. at least it will fly reliably. Thanks.

I was experiencing similar glitching, or movement in other servos. I was running a ppm receiver , I switched to a pcm and that got rid of the glitching. I was running hitec 965 mg's in a 27% cap. I think these servos throw out some interference, thought it was the servo reverser but I tried it also by flipping one of the servos and using a y-harness and it still glitched.
