HEP-L 21*7 High-Performance Ultra-Light Rotor Propellers

3% Increased Flight Time · More Stable Forward Flight · Motor Collaborative Design

• Single Propeller Weight 32g

• Recommended RPM Range 2650~3700RPM

• Recommended Thrust Range 1.2~2.3kg

Extended Flight Endurance

Aerodynamic optimization improves hovering efficiency and increases effective flight time by up to 3%

Optimized Motor Propeller Matching

Designed specifically for T-MOTOR efficiency motors to achieve optimal RPM and torque matching

HEP-L is precisely matched with T-MOTOR's high-efficiency motors enabling long endurance multirotors with flights of 60~90 minutes

Forward Flight Vibration Suppression

Enhanced propeller structure reduces vibration and improves wind resistance during cruise

Lightweight and Durable

Breakthroughs in lightweight and toughness

Scaling industrial-grade lightweight processes for ultra-lightweight mass production

HEP-L 21*7 single propeller weighs about 32g

Enhanced Damage Resistance

Engineered high-toughness resin surface fiber reinforcement, and damage-tolerant design limit micro-damage propagation for enhanced reliability

Under identical 6J impact energy, HEP-L achieves a 1.93mm impact depth versus 2.54mm for NS, delivering 24% improved impact resistance
