The Sparko F8 Concept
The Sparko F8 was engineered with the professional-level racer in mind. From the very beginning, corner speed was the highest priority, driving every design decision while maintaining uncompromising build quality and maximum durability. The result is a modern, fast, and agile platform that incorporates the latest design philosophies in competitive off-road racing.
Named after the F8—one of the most sophisticated fighter jets ever built—the F8 reflects precision, performance, and advanced engineering. Designed as a future-focused platform, the F8 is built to evolve, with performance upgrades and optional components continuously developed through rigorous testing by Sparko’s factory drivers and engineers.
Supporting Features
Race-Focused Geometry: All components work together to give the F8 exceptional steering, corner speed and durability straight out of the box.
Steering & Front-End Precision
16° Aluminum C-Hub (Standard): Delivers sharp initial steering response with increased precision on corner entry.
Rigid Front Upper Arm: Increases suspension rigidity, helping the front end track accurately and maintain a consistent, predictable steering feel.
Aluminum Steering Bellcrank: Creates a highly responsive, slop-free steering system with enhanced accuracy and long-term durability.
Powerful and Efficient Drivetrain
The F8 features a robust three-differential drivetrain built to handle high power with maximum efficiency. Both the front and rear diffs use high-capacity 43/13 ring and pinion gears for strength and reliability. The center differential comes standard with a 46T spur gear paired with a 13T pinion, delivering smooth power transfer and consistent performance. A dogbone center driveline reduces rotating mass, while universal driveshafts at the outdrives ensure efficient power delivery and durability under extreme load.
Molded Electronics Tray
The F8 features a sleek, molded electronics tray that securely houses the servo, receiver battery, receiver, transponder (AMB), and switch. Optional grommets can be used to seal the tray, helping protect electronics from dust and moisture for reliable performance in harsh conditions.
Suspension
Dual Sway Bar Sets Included: Supplied with both low-traction and high-traction sway bar options, allowing quick tuning to suit changing track conditions.
7075 Hard-Anodized Aluminum Shock Bodies: Built to withstand big jumps, rough terrain, and high-speed landings while maintaining consistent damping and control.
Optimized Shock Springs:
Hard front springs combined with medium rear springs provide a balanced, versatile suspension setup that works across a wide range of surfaces.
Sparko Body Shell
The F8 body is engineered to maximize steering response and corner speed while maintaining excellent balance and stability over jumps for confident, consistent performance.
3-in-1 Rear Wing System
The Sparko rear wing features an adjustable wickerbill that can be run with holes, without holes, or completely removed. Combined with multiple wing-mount angle options, this system allows precise tuning of downforce, stability, and overall handling.
