I took the motors out of an RC car, used the wheels as flywheels and rigged it up to a tommy 20. The results are pretty impressive with well over 100ft ranges.

The reason I wanted to try this is because the linear velocity of the flywheel is in direct proportion to its diameter as long as the rpms are the same. This mean the bigger the flywheel the better the range and since most flywheels are only about 1in these 2.25in wheels along with much beefier motors result in great ranges.

You just have to wire one motor + to -, -to+ so it spins the opposite direction as the other.

I shot some with only 12v but these motors run at 9v stock so I should be able to safely run them at around 18-20v and either get even better ranges or have a blaster that turns darts in to confetti.
