150mm tank

This is the tank I've made for my 150mm gun. In it's description I wrote, that I'll make some aiming system for it. Do do it I unfortunately have to redesign the gun (ammo is separated from the rest of the tank, which, I think, causes lags). Performance issues it causes won't make it possible for the VIZZY to run any program more complex, than few simple commands, like theese for this gun. That's why it will take some time for me to make improvements and to finish what I wanted to do. For now we have this.
ag1: shoot
ag2 does nothing
slider1: gun elevation (dont move it while loading the gun)
slider2: gun traverse
throttle: open door (they're on the rear of the tank)
Set the refresh frequency (physics settings) to at least high, otherwise the gun will jamm.
Have fun
PS. I know, it's not a tank, more like transporter... Another reason to redesign cannon, it's ridiculously hudge, especially its magazine, which is very exposed. And for now it won't work in space.
