For those worried that the RF-002 upgrade kit has been sold out, I would like to share news that a new batch will be made sometime in February!  So far, close to 200 out of 350 kits have been sold for the main set.  The new batch will be made in a higher quality resin.  Also, there are plans to remove all QC issues which the first two batches had, along with a better fitting for the helmet parts.  Stay tuned for more news in the coming months.
