LEGO Pullback Motors in Series [HD]

In this video, I demonstrate using LEGO pullback motors in series and parallel. With pullback motors in parallel, you will get more power. With pullback motors in series, you will get more runtime. Runtime is how long each motor lasts before completely unwinding.

When using the pullback motors in parallel, you just simple link their shafts with an axle. However, when using them in series, it's much more complicated. It took me FOREVER to figure out how to do it. Furthermore, the way I used to link the pullback motors in series is very unstable. It only works maybe one out of two times and thus, its just a concept. This is also the reason why I didn't make instructions for this either.

Series and parallel are words commonly used in the electrical and electronics industry. The most easy way to understand what series and parallel means is by using batteries. If you place two 5 volt batteries in series, linking one of the positives to the other's negative, you will end up with a 10 volt battery. If you place two batteries in parallel, linking their positives and negatives together, you would still have a 5 volt battery, but it would last two times as long as just one battery. You can use as many batteries as you want to achieve the voltage or battery life you desire. Note that this explanation is quite simple, and in reality there are several other factors such as the internal resistance of the battery and output current.
