HQProp Durable DP5.1x4.1x3 Tri-Blade Propellers (2CW+2CCW)

HQProp Durable DP5.1x4.1x3 is a 5.1-inch tri-blade polycarbonate propeller for 5-inch FPV freestyle and racing quads, supplied as a set of four (2 CW + 2 CCW). The Durable line is built for impact resistance: the blades flex on contact rather than snapping, so a set keeps flying through hard landings while thrust and throttle response stay consistent.

Key features

• 5.1-inch disc, 4.1-inch pitch: slightly more diameter than a plain 5-inch prop for extra thrust, with a moderate pitch that keeps mid-throttle smooth for freestyle lines and race laps.
• Tri-blade layout: balances cornering grip against efficiency and top-end speed.
• Durable polycarbonate: resists cracking and holds its shape after crashes.
• Four colours: Grey, Light Green, Light Blue or Yellow; the brighter shades are easier to spot when searching for a downed quad.
• Full quad set: two clockwise and two counter-clockwise props per pack.

A 5.1-inch prop sweeps a little wider than a 5-inch one, so check tip clearance against the frame and neighbouring props on compact 5-inch frames before the first flight.
