Default Sanwa Exzes X / servo twitching

Hi All,

after some opinions/suggestions... set my nitro up after years of not using it and the servo i put on thottle was one i used to use on steering on another car. had an issue where it would just stop working / lock up - you couldnt turn it by hand as it was still powered - it was as if it was being told to stay neutral. steering servo fine. assumed faulty servo so swaped with a new / known working one. worked fine for around 15 minutes and now does the same thing.

if you turn power off/on then it might work for a few seconds but then stops again and might work for a bit more. steering remains fine. tried swapping the servos over on the receiver and throttle control worked the steering but steering did not work thottle - points to servo issue.

a very kind chap was going to lend me a servo and i tried two - but i could hear them both twitching when they were plugged into throttle channel even though transmitter was at neutral. turn transmitter off and noise stopped. it was as if the throttle was twitching. i wonder if the throttle on the transmitter is knakered and wont hold 0 - wondered if this could have damaged two servos - asking for constant small movements (wasnt enough to actually move the servo).

so ive tried the transmitter on computer using a VRC dongle and i can see the crosshair moving slightly, but tried different receiver and different transmitter and its the same on all of them so im a bit stumped...

anyone got any ideas what issue is or how to sort? i thought it was solved with faulty transmitter until i plugged into pc.

as a side note i have occasionally had it recently turning on electric the speedo would take 10-15 seconds before it turned on fully so this also leads me to think that the transmitter wont hold 0. just confused me with the pc not showing any jumping/twitching.

any suggestions please??
