Help Needed ... glitchy servo, have videoed the problem !

[szymanski2oo1]

hi all

i have a futaba s9351 servo in my sct truck, its got some odd glitching going on, but only really noticeable when there is no pressure on the wheels... I have uploaded a video clip of what its doing to my dropdox account if anyone doesn't mind taking a look and passing on a diagnosis!

i have brand new futaba receiver in it, but the same problem happened with the previous receiver, also i have tried two different tekin rx8 speedos and the same problem exists!

any help appreciated

cheers

cheers fella, thought about that but the glitching is a recent thing, its been running fine most of the year, im guessing the servo is nakered, but just wondered if theres something im missing before i buy a new servo ! :cry:

the pot in the servo is playing up, either needs cleaning or replacing, this often happens after getting damp or getting fuel in them with nitro's. the servo doesnt see a particular position properly, commonly neutral so keeps searching for it....

ah .. do you think cleaning the pot is a diy job? ive replaced gears before but thats as far as i go. any tips on how to do it?
