NERF N-Strike Elite Demolisher 2-in-1 review yesterday. Now it's time to see how this thing ticks because... let's face it... we ALL want to make this blaster better. The best way to learn how is to take a look under the hood. It doesn't take a Nerf Genius to figure out how to mod the Flywheels on this thing. The Rocket Launcher is really what had me thinkin could use some firepower upgrades. Below is a quick video showing the internal layout of the Demolisher so YOU can have a plan of attack on how to improve it based on the space and existing hardware available.
