The Q&A was answered:
"Thank you for pointing out this discrepancy! While the original intent was to only allow the M7-RS775-18 part number for the 2015 season, due to this issue Team Update 2015-02-20 revises Table 4-1 in R18 to include both the M7-RS775-18/RS775WC-8514 and the M7-RS775-12/RS775PH-6221 as legal motors."
devg29, your pictured motor (a Banebots M7-RS775-18/RS775WC-8514) is officially legal!
