| Gemfan 31mm 3-Blade 1.0 Shaft Propellers | Lightweight micro quads | Ultra-lightweight design for reduced hub weight |
| Gemfan 1210 31MM 2-Blade Propellers | Versatile power and control | Two-blade efficiency with strong off-the-ground thrust |
| Gemfan 1210 2-Blade PC Propellers | Ultra-light tiny whoop upgrades | Low weight with high efficiency for micro drones |
| Gemfan Durable 31mm 2-Blade Props | Durability-focused builds | Ultra-durable PC material for rough flights |
| Gemfan 35mm 3-Blade Props (1.0mm Shaft) | Small form-factor micro quads | 3-blade power with 1.0mm shaft compatibility |
Gemfan 31mm 3-Blade 1.0 Shaft Propellers
Best for ultra-lightweight builds where every gram matters. These 1219S 31mm 3-blade props feature a 1.2 inch diameter with a 31mm paddle and a 1mm center hole. They are designed to minimize weight while preserving blade thickness and aerodynamic efficiency. This makes them suitable for TinyWhoop airframes aiming for longer flight times and nimble handling. Best for pilots prioritizing efficiency and minimal inertia during rapid yaw and pitch maneuvers.
Limitation: The extremely light construction can be less forgiving in rough outdoor conditions or with heavy landings, where stiffer props help maintain shape. Best used on smooth indoor tracks or soft landings.
Gemfan 1210 31MM 2-Blade Propeller (Set of 4) – 1mm Shaft
Best for pilots seeking a balance between power and control. The 1210 31mm two-blade design provides solid off-the-ground thrust with a clear black finish. The 1mm shaft accommodates common micro motors and is well-suited for 1S micro quads. The two-blade configuration emphasizes tighter response and easier durability in routine flying. Choose this if you want consistent, predictable behavior during quick throttle changes.
Caution: Two-blade props can feel different compared to three-blade versions in hover efficiency; expect slightly different flight characteristics around hover and slow-stabilize scenarios.
Gemfan Durable 31mm Props 1210 2-Blade PC Propeller
Best for durable micro quads that endure frequent indoor crashes. These 1210 2-blade props use high-quality PC material to maximize efficiency and resilience. Weighing about 0.19g per prop, they maintain lightness while offering improved durability for bumpy indoor flights or beginner practice sessions. They are suitable for 1.2 inch diameter, 1.0mm shaft setups often used in tiny whoop configurations.
Limitation: Slightly heavier than the ultra-light variants, which can marginally affect flight time in very weight-sensitive builds. Best paired with motors that tolerate minor extra weight without sacrificing agility.
Gemfan 35MM 3-Blade Props for 1S Tiny Whoop
Best for small, powerful micro quads that still seek strong lift. The 35mm three-blade propellers are designed for micro Tiny Whoop frames and come with a 1.0mm shaft hole compatible with 0802SE motors or other 1.0mm shaft motors. Weighing about 1.23g per set, they deliver a balance of thrust and control for compact builds. Choose this if you want more thrust for fast climbs without significantly increasing motor load.
Caution: The larger blade area can introduce more torque, so ensure your flight controller gains and prop direction are correctly configured to prevent twitchy behavior in tight spaces.
Buying Guide: Key Considerations for 1 Inch Propeller Shafts
- Propeller size and shaft compatibility: Confirm the motor shaft diameter (commonly 1.0mm for micro quads) and ensure the propeller hub fits without binding.
- Material and weight: PC (polycarbonate) props offer a good balance of weight and durability. Lighter props improve efficiency but may be less durable in crashes.
- Blade count and design: Three-blade props provide more lift and stability at the cost of efficiency; two-blade designs are typically lighter and more responsive for quick maneuvers.
- Flight application: Indoor beginners benefit from durable, stable props, while advanced pilots may prefer ultra-light options for longer flights and sharper control.
- Durability vs. performance: Consider the typical wear and crash scenarios. Higher durability is beneficial for training and casual flying, while ultra-light props shine in performance-focused setups.
Frequently Asked Questions
- What is a 1.0 shaft propeller? Answer: It refers to the propeller’s central hole diameter, which must fit a 1.0 mm motor shaft used on many micro drones.
- Are three-blade props better for Tiny Whoop drones? Answer: They can provide more lift and stability, but may reduce top-end efficiency compared to two-blade designs.
- How do I choose between plastic and PC props? Answer: PC props are typically lighter and more efficient; however, some setups benefit from the added durability of PC for crashes.
- Can I mix different brands of 1 inch propellers on the same quad? Answer: Mixing can be possible if shaft size, pitch, and blade count are compatible, but it may affect flight characteristics; use consistent pairs where possible.
- Will larger blades fit smaller frames? Answer: Larger blades increase lift but require careful weight and center-of-gravity management to maintain control.
- What maintenance is needed for propellers? Answer: Inspect for cracks or chips after landings, replace damaged blades promptly, and ensure hubs are secure to prevent in-flight prop failure.
