🪨 Crawler or Speed Car? This one is a CRAWLER
🪨 Rock Crawler (this model) — slow, powerful and precise. Gear reduction, high-torque motor and long-travel suspension let it climb rocks, steps and slopes at walking-to-jogging speed.
🏎️ Speed / Basher Car (buggy, truggy, monster truck, rally) — built for 40–70+ km/h and jumps on open ground; not good at slow climbing.
Speed level:
Slow & controlled (≈12 km/h) — ideal for climbing and trail driving.
🔰 New to Hobby-Grade RC? What These Specs Mean
- Hobby-grade vs toy-grade: hobby-grade RCs use proper motors, ESCs, servos, oil shocks and metal parts, and every part can be replaced or upgraded. Normal toy RCs usually can't be repaired.
- Brushless motor: more power, more efficient and longer-lasting than cheaper brushed motors.
- KV (3500KV): motor rpm per volt. In a crawler, gearing turns this into strong, slow torque for climbing.
- ESC (45A): the "brain" that controls the motor; 45A means it can handle heavy climbing loads.
- 2S LiPo (7.4V): "2S" means two battery cells. Higher "mAh" = longer run time.
- Servo (20 kg): the steering motor. Higher kg = stronger steering when wheels are stuck between rocks.
- 1:12 scale: 1/12 the size of a real truck — about 39 cm long, best enjoyed outdoors or on a home obstacle course.

🛠️ Before You Drive — Care & Returns
- Fully charge the LiPo before first use with the supplied charger; never leave LiPo batteries charging unattended, and unplug the battery after every run.
- Check screws and wheel nuts after the first few runs — vibration can loosen them on any hobby-grade RC.
- Tyres, shafts, arms and links are normal wear parts in the RC hobby. Damage from crashes, water, wrong batteries/chargers or modifications is not a manufacturing defect.
- Please record a clear unboxing video and test the car on arrival. Return and replacement terms are as per our Return Policy.
