Description
Overview
The YIKONG YK4107 PE is a powerful 1/10-scale 4WD brushless rock crawler with a low center of gravity (LCG chassis), portal axles, a 2-speed gearbox, and full LED lighting. Thanks to its robust drivetrain and realistic scale details, it is perfect for trail driving, technical crawling, and off-road adventures.
The main difference from the PRO is that it no longer has tank turn functionality or manual diff locks; otherwise, it retains all features.
The YK4107PE is supplied fully assembled in RTR form with the electronics pre-installed. Still required: a 2S or 3S LiPo battery, battery charger, and batteries for the transmitter.
