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

As far as I can see, only the connections to the motor are severed, so I think it should be easy to fix with some solder. The problem is, I do not know where to solder, as there are no visible copper tracks on the PCB. Any help or guidance here would be greatly appreciated.[...]By the way, the servo I'm using is the HS 311 standard.
The only thing is that the pulse required to make it stop spinning seems to have changed (probably because I replaced the potentiometer with two identical resistors).. So would any of you be able to guide me into how I could find out what the value to make it stop spinning is?
How much have it changed?If it's in the interval 1495µs to 1505µs (i.e. a 5µs tolerance on the 1.5ms) you can consider it centered OK. If not, the exact pulse duration will be helpful in estimating the new values.
