its going to be pretty exensive to do a 7 pound electric 808. my nitro 808 weights 7.2 pounds. and it is stock. and i know the electric stuff is going to weight more and xray hop up parts that lighten it are not cheap.

but good luck and if you do get it to 7 pounds. good luck controlling it lol. i have a little 3 port motor in mine that can keep up with any motor. even my buddys crazy modified nova's
