All of the above make it ROAR illegal.
Some people have put the Binary2 arm in a Monster can and have good results.
There are 5 motors
Revenge of The Monster - 40 lamination stack, legal wire length, 2 magnet can - green in color - EPIC27 on tag - Drill balanced arm
The Epic Roar Stock - 36 lamination stack, legal wire length, 2 Magnet can - Gold/Bronze in color - EPIC27 on tag - Drill balanced arm
The Binary 2 Outlaw Stock - 36 lamination short stack, does not meet required wire length, 4 magnet can - Satin/Silver looking can - Epoxy Balanced Arm - EPSTK27 on tag
The Trinity Monster handout - Purple endbell, Chrome can - 40 lamination stack, meets required wire length - Epoxy balanced arm
Then the Epic BRCA stock - not sure what specs this meets as I have never ran one.
Hope that helps.
