Ultimate Nerf Stryfe Mod - Mass Effect
This modification will allow you to control the motor speed of a Nerf Stryfe and thereby the impact force of the Nerf darts.
The Stryfe is my favourite Nerf gun, but like all electronic blasters in its stock form it is kind of weak. There are multiple instruction on the web on how to perform a voltage mod, but to change the speed you would always have to use different batteries. You might ask why would you want it to run on a lower speed? Well if you have ever heard how loud it is after the voltage mod the question answers itself.
As an added feature, the speed of the motors is indicated by nine LEDs on the side of the blaster.
