BANZAI MOM,
the 13*3 is pretty popular
the 12*2 is made for this track
some of the guys would like to try some 10s and 11s
but stock motors dissappear as soon as they hit the display!!!....so i say make him buy like 3 or 4 of each...at least so the suppply will last more than one race night!!!
HAHA THANKS!
JONNY
