What upgraded configurations does the LDRC LD18401PRO RC car feature?

LDRC LD18401PRO is equipped with a FOC sensored brushless motor delivering high low‑speed torque, full‑car CNC metal half‑shafts, and a 9g servo for precise response.

• Original issue: Loud motor noise and obvious high‑frequency squeal during low‑speed forward/reverse driving.
• Improvement: Rewrote the motor control program (hardware unchanged) and optimized low‑speed operation logic.

2. New dedicated motor heat sink for improved heat dissipation

• Original issue: No independent cooling device; the motor easily overheats during prolonged aggressive off‑roading or low‑speed high‑load operation, causing power drop and shorter service life.
• Improvement: Added a semi‑enclosed motor heat sink (not included in the old version) for better heat conduction by fitting closely to the motor housing.

3. Significantly enhanced drag brake for more stable off‑road and slope control

• Original issue: Weak drag brake; the car coasts a long distance after releasing the throttle, prone to sliding backward on slopes with poor low‑speed off‑road controllability.
• Improvement: Increased drag brake output via program adjustment to strengthen braking drag force.
