High-efficiency 5" propellers with a 3.0" pitch. Optimised for stable flight and extended battery life in micro drones. Includes universal paddle ring adapters for varying shaft sizes.
Achieve ultra-smooth stability and extended flight times. The 5030 Orange Propeller Set is designed for the "efficiency-first" pilot. While aggressive racing props focus on top speed, the 3.0" pitch on these blades ensures your motors draw less current, keeping your electronics cool and your flight times long. It is the perfect choice for indoor flight, technical aerial photography, and educational robotics.
Probots™ ProSpec Grade Stability
Crafted from high-tensile glass fiber reinforced nylon, these propellers are Probots™ ProSpec Grade. This composite material provides the necessary rigidity to prevent blade "deformation" under the high RPMs of 1806 and 2204 series motors. The precision-molded 5mmaperture ensures a direct, vibration-free fit on standard FPV motor shafts, while the included Paddle Ring (Adapter) set provides backward compatibility for smaller motor configurations.
Diameter: 5.0 Inch
Pitch: 3.0 Inch
Rotation: 1 x Clockwise (CW) + 1 x Counter-Clockwise (CCW)
Material: High-Strength Reinforced Nylon
Colour: Orange
Centre Hole (Aperture): 5.0mm(Primary)
Adapter Rings: Included (Fits 3mm, 3.17mm, 4mm shafts)
Weight: ~9g per propeller
Recommended Motors: 1806, 2204 (2000KV - 2400KV)
Micro FPV Quads: Ideal for 180mm–210mm frames like the ZMR180.
Beginner Training: Low pitch provides a much more forgiving throttle curve for learning.
DIY Hovercrafts: High-efficiency thrust for surface-effect robotic projects.
Unlock New Capabilities (Project Evolution)
Feature Upgrade: The 5mm native aperture eliminates the need for spacers on most modern brushless motors, ensuring a lower profile and higher rotational accuracy.
Effort Level: Beginner. Simply secure to your motor shaft using a standard M5 Nyloc nut.
Package Includes:
1 x 5030 Clockwise (CW) Propeller (Orange)
1 x 5030 Counter-Clockwise (CCW) Propeller (Orange)
2 x Sets of Paddle Ring Adapters (Standard micro sizes included)
What does "5030" mean? "50" is the 5.0-inch diameter; "30" is the 3.0-inch pitch.
Will these fit my 2204 motors? Yes, this is a very common pairing for stable 5-inch builds.
How do I tell CW from CCW? CW propellers rotate clockwise (viewed from top) to push air down; CCW rotate counter-clockwise. Markings usually indicate rotation.
Is the 5mm hole too big for my motor? If your motor shaft is smaller than 5mm, use the included adapter rings to center it.
Are these better than 5045 props? They are more efficient and offer better battery life, whereas 5045 props offer more top speed.
Are they durable for crashes? Reinforced nylon is flexible enough to take minor hits but rigid enough for performance.
Do they come in other colours? Yes- Black & Orange
Will these help with "jello" in my video? Yes, the low-pitch and stiff material minimize vibrations.
What is the hub thickness? Approximately 7mm.
Can I use these on a 3-inch frame? No, they will strike the frame. Use 3-inch props for 3-inch frames.
Do I need a specific prop nut? Use a standard M5 flanged lock nut.
Are they factory balanced? They are high-precision moulded, but we always suggest a manual check for professional work.
Can I use them for a pusher plane? Yes, provided the orientation is correct.
What is the weight per pair? Approximately 8g.
How many props are in a pack? You get one pair (1 CW and 1 CCW).
Are they suitable for high-speed racing? They are more for stability; racers usually prefer 4.0 or 4.5 pitch.
What happens if I install them backwards? Your drone will push air up and fail to lift. Markings must face the sky.
Can I use these on 4S batteries? Yes, as long as your motor/ESC can handle the 5-inch load.
What is the maximum RPM? These are rated for standard brushless speeds up to 30,000 RPM.
Is there a warranty? Standard manufacturing defect warranty applies.
