The 13mm is not standard on the Novak 13.5 motor and has to bought seperately.
In the coming weeks there is going to be feed back coming as more motors start meeting ROAR specs and guys are still experimanting with the other brands available.
Some swear by Novak others by LRP, Orion and new kid SpeedPassion.
probably hear what is working after this weekends Snowbirds too.
