... and some minor modifications...
5.8 lbs total.. are you kidding me? my god. where is the weight savings from?
I can guess the battery is lighter than my 8000mah.. but the LRP 10L is basically the same weight as Tekin 4300pro4 hd. we have the same type of titanium bolt kit. your esc is down right tiny but that can only save max 0.1 lbs (44grams or so).. we both have the Lunsford ti turnbuckles and I assume hinge pins. no body, that's a save but not much. 256 grams mine weighs.. so that's 256+44 = 300 grams or .66 lbs. does not account for the 0.95lbs lighter weight your truck has FAO.
Impressive!
edit: why is your rear brace gone (one next to rear center drive axle)? that has to be 25grams. and I noticed your battery and esc wires are more optimized for reduced length.. along with only 12 gage wires on your battery, nice again. any more tricks appreciated. are there titanium axles for this bad boy?
