2Pack 38mm 3Blade PC Propellers (Left + Right) — For Flytec and general RC boat models Key benefits Balanced thrust and stable handling: Includes one lefthand and one righthand propeller to counteract torque and deliver smoother, more predictable control. Reliable fit and stable operation: 38 mm rotating diameter with a 2.2 mm hub hole designed to fit 2.3 mm motor shafts, providing a secure pressfit for consistent performance. Durable construction: Molded from PC (polycarbonate) for reliable performance in toy boats, bait boats, and model projects. Features Design: 3blade propellers for efficient propulsion and improved thrust in small watercraft applications. Rotation options: Supplied as a matched left and righthand pair to suit twinprop or counterrotating setups. Compatibility: Specifically compatible with For Flytec models and broadly suitable for other RC boat models that use 2.3 mm motor shafts. Size: 38 mm diameter (rotating), 2.2 mm hub hole diameter optimized for 2.3 mm shafts. Practical applications or upgrade props on toy boats and small RC watercraft to restore performance after damage. Install on fishing bait boats to improve push and trimming control during trolling and bait deployment. Use in DIY boat model builds or repairs where a matched left/right propeller pair is needed for balanced propulsion. Quick installation tips Confirm motor shaft diameter is 2.3 mm before installation for the intended secure fit. Clean shaft and hub seating area to ensure proper alignment and reduce vibration. Use matched left/right props for twinprop installations to minimize yaw and improve handling. What you get Two 38 mm, 3blade PC propellers: one lefthand rotation, one righthand rotation. Compatibility with For Flytec and general RC boat models using 2.3 mm motor shafts. This propeller pair is a straightforward, reliable replacement or upgrade for small RC watercraft and model projects where size compatibility, matched rotation, and consistent performance are required.
