Hi bendodgey77
If you going with the ASP Plug-and-Play Champion 3.0
Here
You will not need the 18650 battery or charger, they are part of the 3.0 kit
You will not need the Stunt Warrior and it’s switch, as these are for a setup without sound.
You will need the ASP Plug-and-Play LED
Here a momentary switch either lighted
Here or un-lighted
Here I suggest the lighted.
Everything else you have correct.
So go ahead and start designing your saber, use the designer
Here. The beauty of the ASP system is that there are almost no limits for what you can design! So use your imagination and build away!
Good luck and MTFBWY
