Servo very slowly pulls up when i arm my plane.

I Was just wondering if any one has been in the same situation as me.
I plug in the battery and the servo very slowly pulls 1 way to full deflection.
It's a very cheap servo and i have many so easy to swap out but not sure of the cause.

A faulty servo can be the cause but not always!
Recently I had a rudder servo start to do the same and I discovered that the potentiometer that is connected to the rudder stick in the transmitter was faulty or somehow full of dirt Etc. I simply replaced the entire gimbal with a replacement unit from Banggood and now all is working fine again!

Have fun!

Easiest just plug in another servo to that port and see what happens.
