Buy an Axon, Axon II, or Axon Mote and build a great robot, while helping to support SoR.

When I adjust the pothead, the gears stop but after a while, they start to spin again. This happens again and again. Am I doing something wrong?
This is a really noobish question: how does the value of the resistors used affect the servo
and would these resistors produce good results?
They just create a voltage divider with half the supply voltage out on the common node, this is how the pot will work when the wiper is in the center position.It's a feedback to the control circuit, which is comparing the commanded value to the feedback from the pot and when in the middle, it equals 1.5ms pulses in.There's a timing gap called dead band in the control electronics, to avoid the motor constantly hunting and if you initially set the pot close to one edge of the dead band value, a little temperature change will eventually make it drift.You could try finding the two exact positions where it starts to move and place it right in the middle of them, but the two resistors will be easier.
Why buy from Rapid (paying shipping as well) when you can get those in your nearest shop?
I replaced the resistors with two 2.2K R resistors with equal resistance (measured beforehand), but when I run the hold_servo.hex supplied by admin, it just spins in one direction (fast). Isn't the modified servo supposed to stop when I run hold_servo.hex or should I adjust something?Picture of servo:/Fleet
