need help with a gws v-tail mixer

ok i just got my gws v-tail mixer for my zagi. ive hooked it up and it works, but if i go down fast the right servo will go up, down, then up again. if i go in any direction then to the right both servos go crazy.

its not the radio, ive been using it im my slow stick for months. its not the servos, they were in the plane when i got it and i saw it fly that day. and im doing with the motors off so its not noise from the motors. so it has to the the v-tail mixer.

any idea what it is or how to fix it?

edit: changed directions. i had them wrong

Try twisting the leads from the Rx to servo.

its an electonics system glitch for sure...

How old are the servos? That is a potential sign of servo pot wear-out.

Could be a "flaky" plug somewhere too... or a wire that is about to break in a servo lead

Could even be a bad mixer...

The short wire runs... I personally doubt its induced feedback (which is what the twisted wire is normally used to cure/reduce.)

the servo thats twitching more is the newer one. they are hs81mg, but both twitch, it just the right one does it more. there both under a year old.

the mixer is a futaba plug the rx is a jr, i know there the same other than the plug but could that have anything to do with it.

fhhuber506771 ( is there a quick way to type that )? is likely right, but I like to troubleshoot the cheap stuff first. Even when I KNOW I'm wrong. What I mean to say is don't eliminate anything until you have tested it. I can only say what worked for me.

i was wrong i tested every thing, it has to be the mixer. ive tested that servo on the rx it self and its fine. ill have to email gws. i think the mixer is no good, the wires for the AILE and ELEV are mixed up so the AILE is hooked up to the ELEV on the rx, so im guessing there is something wrong with it.
