OpenROV Build Day 4

Parts for the thrusters. Three fans, three motors,
and some plastic custom adapters.
The outside shell of the motor is held on with a C clip around the shaft. The clip does not appear to be necessary, which is good -- it has to come off, and I could not get them off without damaging them.
I pried the clip open with a probe and a screwdriver.  Once they come off, the shell lifts off. It's held in place by the magnets that make the drive go.
After the housings come off, it's time to remove the shrink-tube and wires. They will get replace with longer wires and liquid electrical tape.
The blue plastic adapters press into the fan. Note -- this one had a lip of plastic around the bottom, and did not slide in all the way. They are a tight fit.
Once removed,  it's time to solder the wires on and to re-insulate them. I'll get back to that shortly. Waiting for replacement wire from the OpenROV folks.
