Hello again Guys.....Now im tried some Heavy Vehicle like Doozer. people know that CAT is the Famous Heavy Vehicle in the World btw i more like the Huge Dumper Truck but im tried this one. This Dooozer have Several Light And Controller. The Light is Headlight (LOL He does have one Headlight) and Tailight, The Controller is Header Control and Header Head Control. I don't know this is Replica or Fictional but im take that Fictional. The Engines is Actualy need to activate Manualy. Read this Description How To Use is: 1. To Activate Engines Use 1, 2.Then To Activate The Header Controller Use 2 And Then Use VTOL Slider To Move It Up And Down, 3.And To Use The Header Head Is Just Click 3 Then Use Trim Slider To Move It Up And Down, 4.The Fourth is Headlight to use it just Click 4, 5.And Finally the Last Thing To Use The Tailight is Activated by Clicking 5. This Doozer is not too Fast you Know Doozer Right it doesn't Fast as you thought. And the Unique Thing You can see These Switch Working In the Controller Seat, If you want too see that just Change View to Camera 1 Ativate The Switch Same As Activate Header and Header Head, Enjoy Mine Maybe ill try about new Transportation Vehicle..........SHIP >:)
