YIKONG YK4106 RC Car Parts Chassis Beam front rear Counterweights 21176
The body has a relatively high center of gravity; pay attention to speed when crawling. You can add front axle counterweight (part number 21174) and rear axle counterweight (21175), or chassis beam front/rear counterweights (21176) to improve weight distribution. The stock front/rear weight distribution is close to 50:50; removing the spare tire and adding front weight can improve crawling.
