Gemfan 1219S 31mm 3-Blade Propellers
Product type: 1.2 inch propeller with 3 blades for tinywhoop craft. Materials: PC, designed for efficiency and durability. Specifications include 31mm paddle diameter, 1.9 inch pitch, 3.4mm pad thickness, 1mm center hole, and 0.18g weight per propeller. These props are crafted to reduce hub size while keeping blade thickness, enabling ultra-light builds with minimal power loss. Best for ultralight Tiny Whoop setups seeking higher efficiency and reduced moment of inertia.
Best for: Builders prioritizing ultra-light weight and efficient thrust in micro quads. Why selected: The 1.0 shaft compatibility and 3-blade design aim to improve thrust-to-weight ratio in tinyframes.
Caution: The data indicates a very light prop weight; verify hub fit and motor compatibility on your specific frame before installing multiple blades on a high-speed configuration.
Gemfan 1210 31MM 2-Blade Propeller Set
Product type: 31mm props with two blades, 1.0 mm shaft. Made from thin PC material to provide strong power off the ground. Best for: Quads needing reliable lift with a straightforward, robust design. Why selected: The 1.2 inch diameter and 1 mm shaft offer solid performance for 1S micro setups while maintaining balance and ease of installation.
Limitations: Two-blade designs may offer less yaw stability in aggressive maneuvers compared to three-blade variants, depending on flight style.
Gemfan Durable 31mm 2-Blade Propellers
Product type: 31mm 2-blade PC propellers with 1.0mm shaft, designed for micro Whoop drones. Features highlight lighter weight (0.19g per propeller) and improved efficiency for Tiny Whoop builds. Best for: Micro quads where reducing weight directly translates to flight time and agility. Why selected: The combination of ultra-lightweight material and compact size supports tighter control in small frames.
Limitation: 2-blade design may have reduced thrust at low RPM compared to some 3-blade options in high-demand flying styles.
Gemfan 35MM 3-Blade Props For 1S Micro Tiny Whoop
Product type: 35mm 3-blade propellers designed for micro Tiny Whoop frames, compatible with 1.0mm shaft hole and 0802/0802SE motors. Weighing about 1.23g per set, these props balance power, efficiency, and control for compact builds. Best for: Micro frame pilots who want more thrust without sacrificing efficiency in a slightly larger 35mm prop size. Why selected: The 1.0mm shaft compatibility and three-blade configuration yield strong lift for small frames that can still benefit from extra blade surface.
Limitation: Slightly larger diameter than classic 31mm props; ensure your frame and motor clearance to avoid prop strikes on full throttle.
Martyr Anodes, Streamlined Shaft Anodes
Product type: Corrosion protection anodes made from zinc alloy with stainless steel slotted head. While not a propeller, these shaft anodes relate to shaft protection for saltwater equipment. Best for: Marine or coastal systems needing low-cost protection for iron, steel, aluminum, or magnesium components. Why selected: Demonstrates an important accessory category for shaft-related hardware, highlighting different needs in shaft maintenance.
Limitation: Not applicable to micro drone propeller shafts; intended for marine use and metal protection in saltwater environments.
Gemfan 35MM 3-Blade Props – Quick Reference
Reference: This entry consolidates 1.0 mm shaft 35mm prop options for micro Tiny Whoop builds. Best for: Pilots seeking a slightly larger prop with higher thrust potential on compact frames. Why selected: It showcases how minor diameter changes influence thrust and efficiency in micro quads while staying within 1.0 mm shaft compatibility.
Limitation: Always verify motor clearance and frame compatibility before switching to larger propellers in a tight build.
Buying Guide: Key Considerations For 1 Inch Propeller Shafts
- Motor compatibility: Verify the shaft diameter (commonly 1.0 mm) and the motor’s prop shaft fit to avoid loose blades or misalignment.
- Propeller material and weight: PC materials are common for tiny props; lighter designs improve efficiency but may sacrifice durability under hard landings.
- Blade count and diameter: More blades generally boost thrust but can reduce efficiency. Match to your flight style—aggressive freestyle vs. hover-focused cruising.
- Frame clearance: Ensure prop diameter and blade width will not strike the frame or battery on full tilt or during aggressive maneuvers.
- Intended use: For Tiny Whoop or micro quads, prioritize ultra-lightweight designs; for more stable indoor flying, two-blade props can improve control at lower speeds.
FAQ
- What is a 1.0mm shaft propeller? A propeller designed to fit motors with a 1.0 millimeter shaft, common on micro drones and Tiny Whoop builds.
- Are three-blade props better than two-blade at micro scale? Three-blade props can provide more thrust and control at higher speeds, but they may reduce efficiency and require sturdier frames.
- Can I mix 31mm and 35mm props on the same frame? Mixing sizes is generally not recommended; ensure frame clearance and proper motor mounts before pairing parts with different diameters.
- Do lighter props increase flight time? Yes, lighter props reduce motor load and can extend hover time in small quads, though durability and efficiency at your flight style should be considered.
- What should I consider when selecting props for Tiny Whoop builds? Look for 1.0 mm shaft compatibility, lightweight PC construction, and a balance between thrust and agility for indoor flying.
