FlyFishRC Flash 1804 3.5-Inch Motor (2450KV / 3500KV)
The FlyFishRC Flash 1804 is meticulously designed to maximize the performance of 3.5-inch FPV builds. By stepping up to an 1804 stator, it bridges the gap between micro components and full-sized 5-inch power trains, providing a substantial increase in thrust and raw power compared to standard 1404 or 1504 motors. This extra torque translates to unparalleled responsiveness and controllable precision, giving pilots a locked-in flying experience whether navigating tight bando gaps or executing aggressive freestyle maneuvers.
Durability and longevity are at the core of the Flash 1804’s engineering. The motor features a thickened base and a robust Uni-Bell structure machined from 7075 aluminum, designed specifically to withstand severe impacts without deforming. Internally, it utilizes a high-strength titanium alloy shaft running on ultra-smooth Japanese NMB bearings. To guarantee stable power delivery under heavy loads, the stators are wound with 220°C heat-resistant copper wire and paired with N52SH magnets, ensuring the motor stays cool and efficient even during intense flight sessions.
Key Features
- 3.5-Inch Optimization: The 1804 stator size provides the perfect balance of lightweight agility and high-torque punch-out power for 3.5-inch freestyle frames.
- Uni-Bell Durability: Crafted from high-grade 7075 aluminum, the Uni-Bell design significantly increases structural rigidity and crash resilience compared to standard multi-piece bells.
- Titanium Alloy Shaft: Reduces overall motor weight while providing extreme resistance to bending or snapping during hard head-on collisions.
- Advanced Thermal Management: Features 220°C high-temperature enameled wire and N52SH magnets, preventing thermal throttling and coil burnouts under heavy throttle loads.
- Tailored KV Options: Available in 2450KV for highly efficient, smooth 6S setups, and 3500KV for aggressive, lightweight 4S agility.
