PR2/PR3 payloads (cost and design)
About the cost reduction of PR2 and PR3 payloads, I asked one of the manufactures and its answer was that there would be some possibilities of cost reduction if the A6000s can be changed to A5000s. Please take this into consideration, if required.

I picked up some candidate parts of the PR2/PR3 payloads whose materials could change from A6061(-T6?? --- it would be nice to be indicated clearly by VIS...) to A5052-H112,
and asked the manufacture company about the cost reduction.
Those parts are for box structres of IM and IRM.

Hope the oreder can be done soon (in low cost!)...
