As it sits right now it weighs exactly 48oz (3lb). I'll need to do some driving tests with the weapon running to verify that I won't need a bigger battery. If I do, I'll have to find some weight somewhere, but I'm really happy with where it is at the moment.
I was hoping to get registered for Motorama again this year, but registration filled up in 3 minutes! So hopefully I'll get in through a wait list. Otherwise I'll find a more local competition to try this out on.
