I filmed this in November of 2006. My mother had loaded the video on to her computer and forgot to send me a copy. I thought that she had deleted it until I found it while fixing her computer. The tank uses a combination gear and chain drive with NPC motors. It is about 170 lbs with a power supply of 24 volts and 18 ah and an anvillus speed controller. The videos of it shooting were lost in a previous clean out.
I hope it can go faster after I rebuild it or at least give it a longer runtime. 10 minutes is not long enough.
