This thing is totally over the top and totally insane love it and my favorite build on the board. I do have a suggestion thou on the fuel, not sure how long real water will last for the gas. I build a lot of low-riders and like to add aquariums to them like they used to have back in the 70's and 80's. I found a resin at hobby lobby , its a two part that you mix together.
these are the most recent that I built, the top one for my Egyptian raider build, and the bottom one for the Aztec warrior build. It last forever once it sets up in about 8-10 hours. You can tint the resin as you are mixing it with a clear like tamiya clear yellow to get the fuel color. Just an idea.
