HQProp DP 7×4×3 Propeller

The HQProp DP 7×4×3 is a tri-blade polycarbonate propeller for mid-to-long-range FPV cruisers and macro cinematic builds, pairing a moderate 4-inch pitch with tough construction for heavier rigs.

Key features

• Tri-blade geometry balances cruising efficiency with the extra thrust larger, heavier quads need.
• 4-inch pitch gives smooth throttle resolution and keeps amp draw down during sustained forward flight.
• Durable polycarbonate construction resists flexing under load and shrugs off rough landings without shattering.
• Direct 5mm shaft fit with no adaptor rings needed, for a clean mount on standard 7-inch motors.
• Supplied as two counter-rotating pairs (2x CW, 2x CCW), enough for a full quad build or a spare set.

Pair with 2806.5-class or larger stator motors on 7-inch long-range and cinematic builds, where the extra pitch gives a bit more acceleration than a milder 7-inch prop without losing cruise efficiency.
