The Saturn 12-turn, 550-size motor is the most powerful motor in the HPI Racing Saturn line-up! If you're looking for an easy to use power boost for your off-road racer or touring car RC, this is the motor you've been looking for! The extra-large size means you'll get extra torque for excellent acceleration and "pop" over jumps, while the 12-turn construction gives you wild top speeds thanks to huge amounts of RPM! Features standard motor mounting screw locations for an easy drop-in fit for most 1/10th scale RC kits.
