if you need a motor that can pretty much pull back anything this is the motor to go with
i use a 11.1 volt lipo and the rof and the spring it is pulling back it is unbelievable this motor is half the coast of the systema magnum motor and it is pretty much the same thing for half the coast.
its great and it halls once it is broken in
will pull back pretty much any spring that you throw in your gun
very very magnetic
there is none
