yep you could buy a used serpent probably not in that good of condition and with no motor or servos and then when you break somthing you wont have any spare parts................. a serpent is good yes but blake drives an ntc3 just fine , do what you wish but a guy with an ntc3 already that needs a motor would be very foolish to pass that deal up switching from an ntc3 to serpent is just like getting into nitro all over againspecially if you dont have a motor
