Offering Stealth’s renowned hybrid-electric drivetrain combined with the well-known Speed Drive two-speed transmission, the F-37’s simplicity is also its strength. Its long travel suspension package and ergonomically designed cockpit are modeled for ultimate maneuverability, whether in flight or glued to the trail.
