Jason, if the part is listed in the additional hardware, you can have as many as that list says, but, for things not in the additional list in the manual, or things from Small Parts, you must use on your robot no more than the quantity listed in the (newer) kit parts list handed out at the kickoff.
That means only two FP's and three Drill Motors, and so on.
If you didn't receive all of the quantity in the list, get on the line to
tammy@usfirst.org, soon!
