removing old solder from the solder tabs on the motor is easy enough..

thinking more about the solder on the esc wires.. i cant cut the wires much because the wires are at a optimal distance.

i am using 63/37 solder and flux.

Solder itself does not go bad from use. As solder ages, it can tarnish and lose conductivity, but a little flux, and rework of the connection fixes that.

The biggest problem with constant reworking of a solder connection (like repeated motor swaps between chassis) can cause component damage. You can degrade the motor or ESC from repeated high heat exposure.

So be careful when soldering not to let heat spread far.

Or try to route wires in a way that allows you to remove the motor and ESC without needing to disconnect the wires.
