Game designer parts counter can't see ~200 parts of tracks, keep that in mind before download. !WARNING! Speeds over 6 mph are dangerous because of tracks angle. Starting with thrust to 25% and AG 1 to activate front driving gear. AG 2 is for rear driving gear. To turn tank use YAW but whery carefull! AG 3 for activating turret with machinegun (VTOL and Trim to aim it). AG 4 and/or Brake for lights. AG 8 for main turret deactivating. Wiki: "The FV4030/4 Challenger 1 is a British main battle tank (MBT) used by the British Army from 1983 to the mid-1990s, when it was superseded by the Challenger 2. It is also currently used by the Royal Jordanian Army as its main battle tank after heavy modifications. The variants for the Jordanian military are to be upgraded using the unmanned Falcon turret." I will make more detailed version with fake tracks later.
