The LDARC X43 1/43 4WD Ready-to-Run Mini RC Rock Crawler is an ultra-small crawler built for indoor and backyard obstacles. This micro RC crawler features a brushed motor, full-time 4WD, front & rear LED lights, and a 2.4GHz transmitter. Its palm-sized chassis and high-articulation suspension make it perfect for crawling over books, rocks, or carpet — no extra purchases needed.
Performance
The tiny brushed motor delivers walking-pace torque with excellent low-speed control. Full-time 4WD and soft compound tires give surprising grip on loose dirt, pebbles, and carpet. The suspension articulates far enough to keep all four wheels planted on 2-inch steps. Real-world crawling speed sits around 1–2 mph, but the torque feels stronger than most 1/43-scale rigs. Users report 25–35 minute runtimes on a single charge.
Build Quality
Metal chassis rails, metal drive shafts, and oil-filled shocks in a 1/43 package are rare and impressive. The plastic body is tough enough for light rollovers. All electronics are splash-resistant, and the LED lights (white front, red rear) are wired cleanly. Minor weak point: plastic wheel hexes can strip with extreme abuse, but spares are cheap.
Control
The included 2.4GHz pistol-grip transmitter offers full proportional throttle and steering with ~30 m range. Response is smooth with almost zero lag — perfect for precise line choice. Trim knobs make centering easy. Transmitter runs on 2×AA batteries (not included).
Design and Features
Scale detailing includes working LED headlights/taillights, spare tire mount, and realistic rock rails. The 120 mAh 1S LiPo charges via USB-C in ~40 minutes. A small on/off switch and charge port are hidden under the removable body. The rig arrives fully assembled and tuned.
Special Notes: True Ready-to-Run — just charge the included 1S LiPo, insert 2×AA in the transmitter, and crawl. Ideal for desk-top courses, kids, or as a pocket crawler for 1/10-scale meetups.
