## Summary description

HQ Prop BN5X4.5O & BN5X4.5RO is a pair of 2-blade bullnose racing propellers sized 5x4.5" including opposite-rotation blades (CW and CCW). Designed for multirotors and racing copters, this set provides matching pitch and diameter for balanced thrust and maneuverability. Suited for lightweight race frames and freestyle setups requiring quick throttle response.

## Long description

HQ Prop BN5X4.5O & BN5X4.5RO are a matched pair of 5x4.5" 2‑blade bullnose racing propellers supplied with one clockwise (CW) and one counter‑clockwise (CCW) blade. Engineered for multirotor and racing quadcopters, the props combine a 5‑inch diameter with a 4.5‑inch pitch to deliver a balance of thrust, quick throttle response and predictable handling on lightweight race frames and freestyle setups.
Advantages
These bullnose props offer consistent blade geometry between the CW and CCW units to reduce vibration and simplify tuning. The 2‑blade configuration reduces drag and improves responsiveness compared with multi‑blade alternatives, while the bullnose tip design helps maintain thrust at high RPMs and increases durability in aggressive flight. Supplied as a matched pair, they eliminate the need to mix different pitch or diameter props when setting up motors with opposite rotation.
Suitable for
 5" and lightweight race quadcopters
 Freestyle multirotors requiring fast throttle response
 Pilot setups where matched CW/CCW props are needed
 Practice and race environments focused on agility and acceleration
Key specifications
 Diameter: 5.0 inches
 Pitch: 4.5 inches
 Blades: 2 per propeller
 Tip style: bullnose
 Rotation: one clockwise (CW) and one counter‑clockwise (CCW)
 Application: racing and freestyle multirotors
How to use
Install the props on motors with the correct rotation orientation: the CW prop on clockwise‑spinning motors and the CCW prop on counter‑clockwise‑spinning motors. Ensure propeller nuts or lock hardware are torqued to the motor manufacturer's specification and that props sit flush against the motor bell. Perform a props‑off inspection before each flight to check for chips, cracks, or deformation. Balance props if vibration is detected during hover or flight testing.
Usage recommendations
Use these propellers with motors and electronic speed controllers matched to lightweight 5" racing frames. Replace any prop showing visible damage before flight. For optimal performance, pair with frames and powertrains designed for high RPM efficiency and perform regular balancing and shaft alignment checks.
