For various reasons (mainly old age), I have several 20-30 year old Futaba and JR servos, and some even older Cox Sanwa ones.
Noticed today that some of the connectors have a nasty geen colour. (See pic)
They could remain green or turn black for all I care, except that I have 3 models awaiting completion since long, so I need 12-15 std servos.
Asked RC Aunt for advice. She said 'Put some nimboo on it'.
So I gave one connector a few drops of lemon for 4-5 secs, then a shot of WD40.
Now it looks shiny golden! (See second connector in same pic)
Is it safe to use now? Or would the wires also have got petrified?
Advice requested...
