Wait a minute before you cut and rewind...I have some PCboard experience and recommend you draw out the layout of the motor tabs are soldered to the pc board and note any labeling at the solder joints. The solder joints on the board ARE the electrical terminations, and you may find out which tabs are the pos, neg and signal. De-solder the motor from the board, solder up your ESC for brushless motor and see what happens!
Let us know how it's coming!

The three wires from the PC board to the motor stator are not +,-, and signal they are 3 phase AC. Don't worry about identifying them they are interchangeable and you are going to replace them with new winding wire connected to a new controller anyway. Don't even think about using the CD controller, it is not suitable for R/C use.
