HQProp 5136R36 2 Positive and 2 Reverse Propeller Set 5.1 Inch 3-Blade PC Prop for FPV Drone Racing Quadcopter Blue and White Gray Yellow
HQProp 5136R36 2 Positive and 2 Reverse Propeller Set 5.1 Inch 3-Blade PC Prop for FPV Drone Racing Quadcopter Blue and White Gray Yellow
HQProp 5136R36 5.1-Inch 3-Blade Propeller Set for FPV Drone Racing and Freestyle
The HQProp 5136R36 propeller set delivers a matched pack of two positive and two reverse 5.1-inch, 3-blade propellers designed specifically for FPV racing and freestyle quadcopters. With a 3.6 pitch and polycarbonate (PC) construction, each propeller weighs only 4.1g, helping to keep overall rotating mass low for quick throttle response and agile handling. The set suits standard 5mm motor shafts and requires no adapter, making it a straightforward replacement for many common FPV drone builds. Available in Blue and White, Gray, or Yellow, the colour options aid visual orientation during aggressive manoeuvres.
Features and Construction
The 5136R36 propellers are built from injection-moulded polycarbonate (PC), a material chosen for its combination of stiffness and impact resistance. The 3-blade layout provides additional grip in the air compared to two-blade designs, while the 5.1-inch diameter and 3.6 pitch balance acceleration with top-end speed. Each propeller has a 13.3mm paddle plate diameter and a 7mm paddle plate thickness, with a centre bore of 5mm that fits most modern FPV motors without a reducing adapter. The set includes two clockwise (positive) and two counter-clockwise (reverse) propellers so a quadcopter can be fully outfitted straight out of the pack.
Material and Build
Polycarbonate (PC) is a tough thermoplastic that resists cracking on light impacts while staying rigid enough to maintain consistent blade pitch under load. The 4.1g per propeller weight is achieved through a thin but shaped blade profile, reducing rotational inertia for faster spool-up and braking. The colour is moulded through the material, so the finish remains visible even after light scuffing from landing or collisions.
Size and Practical Fit
With a 5.1-inch length and 3.6 pitch, these propellers suit 5-inch FPV racing frames that run on 2204-2306 class motors with 5mm shafts. The 13.3mm paddle plate diameter provides a wide base for the blades to spread thrust evenly, while the 7mm paddle plate thickness adds stiffness at the hub without adding significant weight. No adapter is required, so installation is a simple nut-and-lock procedure on standard prop nuts.
Uses and Placement
The 5136R36 set is aimed at FPV drone pilots who need a reliable, balanced propeller package for racing or freestyle flying. The 3-blade design gives extra thrust and grip during tight turns, while the PC material handles the stresses of rapid throttle changes. The pack's combination of positive and reverse propellers means it can also serve as a spare set for pilots who break one or two blades mid-session, or as a replacement for a worn-out set on an everyday quadcopter.
Event or Professional Use
In racing or professional FPV settings, consistent propeller performance is critical. The HQProp 5136R36 set offers matched blade pairs that save time during pit-side replacement. The 5.1-inch size and 3-blade profile provide predictable handling on race gates and obstacle courses, while the PC material holds up to repeated high-RPM use without noticeable flex.
Everyday Home Use
For hobbyist pilots flying at local fields or in back gardens, this set provides a straightforward upgrade or replacement for worn blades. The colour options help distinguish the quadcopter in the air, and the 4.1g weight keeps the overall build light. Because the set includes both rotation directions, there is no need to order two separate packs for a full quadcopter.
Benefits and Buying Value
The HQProp 5136R36 propeller set delivers a complete four-blade package in one purchase, reducing the hassle of matching individual propellers. The PC material extends usable life compared to softer plastics, while the 5.1-inch diameter and 3.6 pitch remain a widely supported size for 5-inch FPV frames. Colour options add a simple customisation touch without affecting performance.
Reuse and Low Maintenance
With proper handling and installation, PC propellers can be reused over many flights so long as they remain undamaged. The 5mm shaft bore fits common motors without adapters, simplifying replacement. After heavy use or a crash, a visual check for cracks or bent blades will indicate when a fresh set is needed.
Why Choose This Product
The HQProp 5136R36 set stands out for its matched four-piece configuration, specific 5.1-inch 3-blade design, and PC construction at a 4.1g weight. The inclusion of both positive and reverse props in one pack saves ordering separate sets, and the colour choices add useful flight orientation cues. For pilots running standard 5mm shaft motors, this is a ready-to-install solution with no adapter required.
