Features:<\/span><\/span>
<\/font>HNR will introduce a new 1\/8 high-performance brushless EP monster truck, named ‘X-MARS MT’. Built on the upgraded original ‘X-MARS’ platform, it’s upgraged and engineered to cater to different needs of hobby players. <\/p>\n

The ‘X-MARS MT’ features a honeycomb-structured,  AIO molded nylon chassis, equipping with 6061 aluminum alloy reinforce plates. The whole vehicle uses steel gears paired with rubber-sealed, dustproof and waterproof bearings. Its transmission system incorporates front, middle, and rear differential units, equipped with sway bars in  front and rear. The frame supports multiple professional parameter adjustments, easily adapting to various terrains. Additionally, it’s powered by a Hobbywing brushless system, compatible with 4-6S high-discharge li-po batteries for exceptional performance. Quick-release design for the motor mount, facilitating players to modify different gear ratios. The original factory comes standard with a remote control and a complete power system,  90% in RTR version (no battery and charger)
