There was talk of a smoke screen system bein used in this thread.
I tried several options. A party fogger with quality fog solution. Results were poor. I think my tank smokes more by itself.
I tried injecting solution straight into the exhaust. Result was even less than the fogger.
I gave it some more thought. My other hobby is pyro. I belong to a group that get together every month or so and put on firework displays. I own remote systems that will ignite fireworks. What I ended up doing was taking a 4in pvc 45 fitting. Mounting 4 2min smoke grenades at the bottme. I wired them to the wireless cue box and had the wireless remote in the turret. On top of the pvc fitting I had a 12v fan that I could turn on/off from the turret. I am able to fire any combination of the smoke grenades that I want. All of them at once. 1 at a time, 2 at a time etc. I was able to test thy system in action at a game a few weekends ago. I was very pleased with the results. With only using 1 smoke grenade at a time it produced a thick cloud of smoke. I was able to lay down smoke in front of the other teams base allowing for my team to advance. I was also stationary at times and the fan did its job in making sure to blow the smoke away from the tank and not back up into the turret. When I get a chance to will post pictures.
