About CROSSRC 2024 UT4 Pro Tiger Shark 1/7 Climbing Car Introduction as follows:
UT4 first generation began in mid-2020, through a special period, so far, the pursuit of power and play methods of simulation model players have undergone tremendous changes. Through the targeted strengthening and transformation of the transmission system, the continuous exploration and upgrading of materials, and the structural strengthening of brushless power. After 18 months of brutal testing of multiple power systems, the 2024 UT4 Pro has been reborn from the ashes.
The 2024 UT4 Pro is designed to be a comprehensive crossover model. The front wheel has a double wishbone independent suspension, and the rear wheel uses a four-point lower blade arm integral hard bridge. The original car is equipped with a mid-mounted two-speed gearbox and a front and rear differential lock system. You can simultaneously achieve a crossover experience of crossing the ash and climbing the dangerous peaks.





The 2024 UT4 Pro adopts a pipe frame inlaid beam design, which combines the space of the load-bearing structure with the hard-core chassis performance of the non-load-bearing structure. The simulated cab space is designed with a complete instrument and control panel, which can accommodate a simulated racing driver; the front position has a simulated engine decoration; the rear axle four-link has added a reinforced ball head buckle and an integral blade arm tie rod structure, so that the rear suspension forms a strong overall frame without losing a flexible twisting posture.


The front and rear differential assemblies use aviation aluminum CNC-carved cages to ensure that the gears will not jump due to axial force under high power. The differential case is made of aviation aluminum CNC, which effectively extends the service life of the differential lock teeth. The large and small teeth are integrally cut and formed from special steel, which greatly improves the impact resistance during rapid acceleration and braking.


The centrally placed two-speed gearbox balances the center of gravity distribution of the vehicle, and at the same time reversely offsets the unilateral tail collapse caused by the shaft effect during rapid acceleration in situ. The gearbox uses all-metal gears and ABEC3-level long-lasting bearings inside, which can basically achieve maintenance-free unpacking when not immersed in water.


The RTR is equipped with a customized 775 motor + Haoying 880 high-voltage electric regulator, with a standard 21T motor gear, and a 3S5000mah90C battery with a maximum speed of 30Km/H. (Speed ​​measuring equipment: SKYRCGSM020)

The original car is equipped with a large-diameter all-metal CNC low-center-of-gravity hydraulic shock absorber, which is originally set for climbing. The frame has a reserved position for installing a secondary shock absorber damping cylinder, which can be optionally installed to increase the vehicle's handling stability during high-speed crossing.



The 2.6-inch lightweight clamped tire hub is equipped with a 152mm diameter simulated MT tread tire, which can adapt to various complex road conditions. The 2.6-inch hub also has a relatively rich CNC style for players to customize


2024 UT4 Pro launches two versions, RTR and ARTR (only the frame is installed without electrical equipment). Both RTR and ARTR are equipped with a tiger shark painted car body and a controllable multi-mode high-power headlight system. RTR is equipped with Haoying 880 ESC, a newly customized high-power 775 motor, a 25KG high-voltage steering servo and 3 high-voltage medium-sized servos (for shifting and front and rear differential locks), and a 6-channel remote control device.
