Ethan's Sweet Remote Control Tank

Ethan, a 13-year-old boy Alexandria and I mentor, designed a tank. We were looking for a project to keep us busy without having to find a new activity each week. With his input and help, I built this tank for him. It uses a tethered remote for control and weighs a little over 42 lbs. It is welded from 1/8" steel plate and is very robust. It  literally shakes the ground when on concrete. I finished the mechanical part last week and on Saturday we painted it. Then I finished the wiring. By that time the batteries were running low, so I charged it for a day. These batteries are massive compared to most RC batteries and I am trying to charge them with a 330 mA wall adapter. Its working, but slowly. A car battery charger would work better. As heavy as it is, it definitely moves. Check it out!

Ethan's dad joined us to paint it.
