How do I add power to K'nex motors? Answered
I'm working on a K'nex automatic machine gun. Unlike most K'nex mg's, this one fires from a hopper and does not have a barrel for every round. Unfortunately, it doesn't work because the motor can't pull back the rubber band. I have one of those clear motors with a red battery pack. I was thinking to hack it so it would take a 9-volt, but i'm not sure if that would work. If anyone can give me some advice, that would be good. Thanks.
