RC enthusiasts, these weighted wheels will seriously upgrade your 1/24 scale crawler's performance! Specifically designed for FMS FCX24M series models including the Range Rover First Generation, Defender D110, Defender D90, and Discovery First Generation. The magic is in the weight - these tires are 72g heavier than stock, which dramatically improves climbing ability and traction on challenging terrain. The counterweight ring adds low-center gravity that helps your RC bike maintain stability on inclines and obstacles where lighter wheels might slip or tip. The plastic construction keeps them durable while the weighted design gives you that performance boost you're looking for. Installation is straightforward if you're familiar with RC maintenance - they're direct replacements for your stock wheels. The 50mm tire size maintains proper scale appearance while delivering functional improvements. Before ordering, double-check that your specific model is compatible to ensure proper fitment. The difference in performance is noticeable immediately - your crawler will handle rocks, gravel, and uneven surfaces with much more confidence and capability. The quality matches what you'd expect from RCAWD - well-made, precise fit, and designed specifically for performance applications. Whether you're crawling indoors or tackling outdoor terrain, these wheels transform your RC experience from casual to capable. They're one of those upgrades that actually makes a measurable difference in how your vehicle performs, especially if you're into technical crawling where every gram of weight distribution matters.
