Hey, I'm going to report you lol... I have the OBR not the rcmk, yet. But yes OBR ports the heads and gizmo did not until recently. Gizmo told me that theirs would make more power but we would have to see it I guess. I have 2the gizmo motors and they kick ass and it is hard for me to tell the difference between my $350 gizmo and my $600 "other "came motors.
