*Ko servo help*

[jonny123]

Hi, everyone.

After a meeting racing outdoors this sunday. In very hot conditions in my TC my ko 2343 servo has gone alot stiffer than it ussualy is. It is also making a strange noise when you move it by hand from left to right. It doesnt feel rough like it does when theres a broken gear it has just gone very stiff.
Anyone know whats wrong with it?
Maybe a dead motor?
Or does it just need rebuilding and re greasing?

Please help me
