This tank is the newest T90 Pro (new molds!) with not only steel gearboxes but also some of the latest electronics from HL, the 6.0S electronics system.
This tank comes equipped with steel gearboxes, metal caterpillar tracks, metal drive wheels, metal road wheels with rubber tires, and metal idler wheels instead of the plastic versions found on the normal tank. This tank also comes with an upgraded lithium battery and USB charger and is available as a desert tan weathered paint scheme.
*This T90 is also a new mold. The lower chassis on/off switch has been plugged and the tank is turned on from the rear of the tank. There is also a new smoke unit which has the pump and heating element separately wired to the motherboard. This is a new version and not widely distributed yet!*
