This video shows how I upgraded my Tommy 20.

I attached a 7.2volt battery pack with rubber bands. Then I connected that to a switch which only goes to the spinners which shoot out the bullets.

When I turn on the switch, it scares your enemy away just with the noise - and it is able to shoot more than twice the distance.

I have two videos here:
The first shows the upgrade in process.
The second is the Tommy 20 in action. It is a bit difficult to see the bullets because they shoot out so quick.

I joined the two videos into one and uploaded it to Youtube.
