Since wire connections are a common source of problems, it seems to me it might be a "con" to have more connectors in the wires.

How do you remove the removable board? do you have to unscrew the motor wires from the victors? or disconnect an (additional) plug in connector? sounds like a hassle or an additional potential source of problems.

If you really can't design the robot to allow easy access to a fixed electronics board, then a removable board might be helpful. My suggestion is to try to make the electronics board accessible, so you don't have to move it to fix any problems that may occur in competition.

Also, you could design the board to be removable under non-competition conditions, such as to swap onto a prototype chassis or something. We did that with our promotional robot, we swiped the complete electronics board from it and got the new kitbot running very quickly.
