YIKONG YK7081 TB8 – 1/8 Scale 4WD TRAIL BREAKER Desert Truck RTR

Where the road ends, the TB8 begins. The Yikong Trail Breaker is a compact 1/8 scale 4WD desert truck built to tackle forest tracks, gravel pits, desert trails and tight technical terrain. With a rugged off‑road SUV body, integrated roll cage, LED headlights and roof‑mounted spotlights, the TB8 delivers scale realism with genuine high‑speed capability underneath.

Sharing the same no‑compromise base as Yikong’s 1/8 performance platform, the TB8 uses a 3674 2800KV brushless motor and waterproof 120A ESC to reach 70+ km/h on 3S and over 85 km/h on 4S. Independent suspension, sway bars and big‑bore aluminium shocks keep it predictable at speed, while the shorter 565mm length makes it noticeably more agile on tight trails compared to a short course truck.
