In the realm of miniature rock crawlers, two giants stand tall: the FMS FCX24 and the SCX24. Both pioneers in the 1/24 scale, promise more than just diminutive dimensions, bringing the thrill of off-road adventures to your palm. In this article, we delve into the technical marvels of these two RC cars, evaluating their features, design, and capability, guiding enthusiasts on which might best suit their adventurous desires. Strap in as we navigate the miniature terrains of these behemoths.
The Gear’s Role
The FCX24’s dual-speed gear comes into play, making it an enticing option. Its faster gear offers an edge over the SCX24, making transitions between sections where low speed isn’t needed not just faster but also exhilarating. Ideal for open spaces, it’s advantageous for moments demanding swift wheel speed for evasion or sudden weight shifts to prevent toppling. Compared to my stock SCX24 electronics, the FCX24 offers superior low-speed control in low gear. Its ability to crawl at blazing speeds during “idle” more than compensates for its mediocre suspension and high center of gravity, allowing it to gracefully crawl on huge rocks.
Controller Dynamics
FCX24 offers a more refined palette of options for controlling the truck, compared to SCX24’s rather simplistic approach. More control can sometimes mean more fun, especially for those who like to fine-tune their RC experience.
Structural Analysis
Undoubtedly, the FCX24 outshines the stock SCX24. Its broader wheelbase reduces its inclination to tilt sideways, with the FCX24 tilting at 41 degrees compared to the SCX24’s 37 degrees. However, the SCX24 is slightly less prone to tipping forward, possibly due to its lower center of gravity.
However, it’s not all rosy for the FCX24. Its battery space is confined, and the fragile elastic strap meant to hold the battery could be its Achilles’ heel. It’s a stark contrast to the SCX24’s spacious battery compartment. The tight space under the FCX24’s hood raises concerns about potential wire entanglement or damage during component swaps. Plus, the FCX24’s tiny screws prove more cumbersome than SCX24’s axial hex screws.
Crawling Comparison
While the FCX24 can comfortably outperform a regular SCX24, it’s humbled by my slightly modified SCX24. Equipped with mudslinger tires, weighted plastic wheels, wider wheelbase brass hexes, and a superior servo system, my upgraded SCX24 is a beast. The total cost of my enhanced SCX24 was around £170, with the FCX24 coming in at £133. Traction is where the FCX24 falters, struggling on steep slopes on my exterior wood/stone track. Its tires seem less grippy, and the bulky front bumper might be a culprit. Though the FCX24 is prone to tipping both forwards and backward more than the SCX24, its throttle control levels the playing field significantly in terms of overall capability.
Material and Design Sophistication
FMS’s FCX24 isn’t just another entry in the RC crawler market; it’s an engineering marvel. The frame is crafted from high-strength nylon, contrasting sharply with the SCX24’s steel components. Compared to the traditional trapezoidal beam composed of metal side beams and plastic trusses, the FCX24 has a lighter yet stronger frame.
Advanced Technology vs. Reliability
Axial’s SCX24, on the other hand, is built on a foundation of reliability and user-friendliness. Although it does not feature a two-speed transmission like the FCX24, it does boast a host of steel components ranging from the C-channel frame rails to the front and rear axles and dogbones. This ensures durability even when tackling the most challenging terrains.
The SCX24’s suspension system is robust, featuring a three-link front and a four-link rear suspension. These, in tandem with coil-over shocks, ensure that the crawler can navigate tricky terrains with relative ease. Powered by a 030-size motor and included LiPo battery, the SCX24 doesn’t cut corners in providing a genuine off-roading experience.
Accessibility and Readiness
The SCX24 model stands out for its convenience. It comes 100% complete and ready to run, right out of the box. It includes a 3-channel 2.4GHz radio system, servo and ESC/receiver unit, a Dynamite® 88T brushed electric motor, and even a 350mAh 2S 7.4V LiPo battery along with a USB LiPo charger. Axial even throws in four AA cells for the transmitter! This all-in-one package serves as a stark contrast to the FCX24, which, while advanced, may require more preparation time and familiarity with RC car assembly.
Conclusion: Which is Better?
Both RC crawlers have their merits and shortcomings. The SCX24, especially when upgraded, shines in specific scenarios like side slopes and steeper climbs. On the other hand, the FCX24’s throttle control can be a game-changer. Choose wisely based on your preferences and the adventures you seek!
