Overview
About SunnySky EOLO 15x5.5 inch Propellers.
The SunnySky EOLO 15x5.5 is a 15-inch, large-diameter propeller moulded from carbon-fibre-reinforced nylon for heavy-lift and endurance multirotors. At around 21 grams per blade with a rated operating speed near 8450 RPM, it pairs the toughness of reinforced nylon with the efficiency of a carefully shaped airfoil, targeting platforms that prioritise lift capacity, flight time and low noise over agility.
The carbon-reinforced nylon construction is stiffer than plain nylon yet more impact-tolerant than pure carbon, so the blades hold pitch for efficient thrust while surviving the rough handling typical of larger working drones. The EOLO airfoil is tuned for high thrust-to-power efficiency and noticeably lower noise than many standard large props, which matters for survey, agricultural and inspection operations. The blades are rated for a wide -20 to 60 degree Celsius working range.
Supplied as a CW/CCW pair, the 15x5.5 suits heavy-lift quads, hexacopters and octocopters running large low-KV motors for aerial work, agriculture, mapping and long-endurance missions. It is aimed at commercial and serious builders who need dependable lift and efficiency on a big airframe.

Buying guide
How to choose.
The EOLO 15x5.5 is built for large multirotors with big, low-KV motors used in heavy-lift and endurance work. The carbon-reinforced nylon gives a strong balance of stiffness, efficiency and durability, making it well suited to commercial survey, agriculture and mapping where flight time, lift and reliability matter more than agility.
Match the prop to your motor's recommended diameter and pitch range and confirm the mounting pattern and shaft or bolt-hole fit before buying, since large props vary in mounting style. Because efficiency and vibration scale with size on big airframes, choosing a prop the motor manufacturer rates for 15-inch blades keeps the system in its efficient, reliable operating band.
Run matched CW and CCW pairs, and balance large props carefully, as imbalance at this diameter produces significant vibration that stresses motors and degrades sensor and camera data. Inspect blades for cracks and delamination after hard landings, and keep spares for commercial operations where downtime is costly.
FAQ
Common questions.
What is the EOLO 15x5.5 designed for?
It is a 15-inch carbon-fibre-reinforced nylon propeller for heavy-lift and endurance multirotors, such as large quads, hexacopters and octocopters used in agriculture, mapping and inspection. It prioritises lift capacity, efficiency and low noise over the agility of small racing props.
What material is the EOLO made from?
It is moulded from carbon-fibre-reinforced nylon, which blends the stiffness of carbon with the impact tolerance of nylon. This gives efficient, pitch-holding thrust while being more forgiving of rough handling than pure carbon props, suiting working drones in the field.
How much does each propeller weigh?
Each blade weighs about 21 grams. Combined with the EOLO airfoil and a rated operating speed near 8450 RPM, this supports efficient, lower-noise thrust on large low-KV motors used for heavy-lift and long-endurance multirotor missions.
Is the EOLO quieter than standard props?
SunnySky positions the EOLO airfoil for lower noise than many standard large propellers, which users have noted in practice. Lower noise is valuable for agricultural, survey and inspection operations where the drone flies near people, livestock or in noise-sensitive environments.
What temperature range can it operate in?
The EOLO 15x5.5 is rated for a working temperature range of -20 to 60 degrees Celsius. This wide range suits commercial field operations across varied climates, from cold-weather survey to hot agricultural environments common in many parts of India.
How many props come in a set?
This listing is one pair, a clockwise and a counter-clockwise propeller. A quadcopter needs two pairs, and a hexacopter three pairs, so order the matching number of sets for your airframe and keep spares for commercial use where downtime is costly.
