This post has built-in some improvements on my old T-90, AG1 for open canopies and lights, AG3 for flares, AG4 for deploy/retract dozer, some unsolvable bug will appear when using AG2 so don't use it. The AA turret is auto-aimed, and you can control main turret by switching camera to the one which named "T90". Engins controled by VTOL, and turning is controled by Roll. I already adjusted the suspension system so it can work better then before, but there might still have problems when driving over bumps-this problem can be solved by removing attached armor.
If you want more mobility or can't bare the suspension system problems, you can remove the attached armor by removing 16 small pillars, it may increase the ability of surmounting obstacles.
Tell me if there's any problems when using.
