This Thunder Power battery retails for $54.95, and the 6.0v Regulator retails for $35.99, for a total of $90.94. Draganfly Innovations offers this package at only $59.95, a 34% savings!!
Did not find the 6v regulator listed seperately and search for same came up empty. Also checked to see if prices listed were CAN or US dollar based.
This is yeilding some good reference sites.
