Last year, we had a compressor and 2 accumulators. Our robot used a piston to actuate the gripper (4 or 5 times a match) and 3 pistons to actuate each wing (once a match).
If your system won't be actuating many times a match, you should figure out how much air pressure you're using each time, and base how many accumulators you need on that. A compressor may be unnecessary depending on the amount of air you're spending a match.
Losing the compressor is a significant chunk of weight, so I suggest figuring out whether you're going to need to refill your accumulators.
