The TD-18 Hellhound is a turreted tank destroyer inspired from M18 Hellcat's chassis and M36 Gun Carrier's 90 mm M3 gun with several tweaks and modification (features semiautomatic breech to increase reloading speed and recoil system). The tracks used my Type 015 Multi-Purpose Gear and Suspension System (MPGSS). Armaments used are one M2HB with 100 rounds, 7.5 seconds reload and red night sights (converged) for defensive purpose, also one 90 mm XM4 gun with 3 second reload, aiming module, and working gun controller. Driver controls: Trim to go forward or backward, yaw to turn left or right, Act3 to activate boost if you stuck or to climb hard obstacles. Driver's tip: Never push the trim fully up or down with this boy, you'll not gonna like it. also the brake is too powerful. Gunners controls: Act1 to enable main gun, and turret controls, Act2 to enable defensive machinegun (all guns controled with roll and pitch). That's all you need to know. I hope you guys enjoy it, it took a long time to make this bad boy. Well, Enjoy!
