Number of motors that a team can use??

[pfreivald]

The total number of motors you can use is clearly delineated in the manual. It is: The number of motors that came in the KOP, except that the Banebots motors are mix-and-match with a total of four.

Thus, two FP motors are illegal.

As for the FP gearboxes, that depends entirely on whether or not they are available as a COTS item. If they are, then it is legal to use as many as you want (subject to cost limitations). If they are not, then you may only use the one in the KOP.
