K, once i start building that part, I'll try to see if I can set that up, but use electronics. I was also thinking some sort of chain that hung from the front of the hull and used a screw drive to push and pull a harness that held the paintball gun, to allow for transverse, mount that on some sort of arc shaped slide, and have another to push and pull that setup. I think it might be too complicated to get to work, and I don't even know that it would work.
For tracks though, would the v belt thing work? I was thinking more on it, i could just use 2 and connect them in between with whatever I could use for treads, and not have to have the 2 extra wheels for each axle. It would sort of be like your Tyng track system, but using v belts and the pulleys for them, since I definitively can get them before i can get a treadmill belt. Since v belts do hold when tensioned, but slip when they get locked up, that would save on a drive system, so I could use the m1 sprocket type chain for that part.
