Looks like the 2015 list for 21.5 motors doesn't list some of the motors you mentioned. Almost everything on the 2015 JMRCA approved 21.5 motor list is a ROAR motor.
Yes, the 2015 list doesn't mention those motors. However, the 2014 and 2013 do. If I'm right, motors released 3 years ago can be used in current JMRCA events.
