wobbily servo's
« on: April 06, 2012, 12:48:59 am »

I have just replaced another servo , this time from my club 500 as it's started wobbling (jittering) . now this has happened to me on several ocasions but this time i think i know what the problem is .
Water , yes my club 500 has recently been going inverted on the pond due to my error (too fast into corners) and i think water may have seeped into the electronics . Has anyone had this problem and would just
stripping it down and drying it out cure the problem .

Oh i have about 5 of them , but i think a couple are just old.

first when you get a servo take the bottom off and put vasline in it

when they get wet asap get back home take it apart use a tissue to dry it and spray with wd40 then leave over night till you put it back together and turn it on also when it gets wet turn it off and unplug it asap

dependant on weather you are operating in salt / brackish or fresh water , unfortunatly if in salt or brackish water the servo / receiver WILL  need rinsing in fresh water to remove all traces of the salt before drying them out again . a hot air gun or hair dryer can be used to expell water quickly , but they are best left hanging in an airing cupboard for a few days in pieces to thourghly dry out .

And then there is the power supply for the servo.  This usually comes via the receiver.  If the insides of the boat have been wet, there may be some corrosion on the terminal pins, there might be some black wire in the wiring.

Some crud might have got into the feedback pot, you can spray a little Servisol into them to give it a clean and that will also lightly lubricate the surface (I'm not keen on using WD40 on electronics).

If you're going to be dunking a servo regularly it's probably worth investing in the servos which are designed to be waterproof.

Thank you lad's , some good info there , not sure of the water as we put salt in the pond to curb the weed's (it works) , so i can see a strip down of the offending servo and a drying off .
Just not sure our lass will believe me when she ask's what i am doing with the vasseline  %) .
