HQProp Ethix S4 Lemon Lime Propeller (Set of 4 — 2CW+2CCW)

Designed in collaboration with Mr. Steele, the HQProp Ethix S4 Lemon Lime is a 5-inch, tri-blade freestyle propeller built for highly responsive flight characteristics. Featuring a moderately aggressive 3.7-inch pitch, it sits squarely between the Ethix S3 and S5, making it an excellent choice for pilots who want a noticeable increase in top-end speed and punch without sacrificing low-end throttle control on custom 5-inch quadcopters.

Key features

• 3.7-inch pitch offers a refined balance of freestyle manoeuvrability and forward thrust.

• High-visibility Lemon Lime colour scheme aids in line-of-sight tracking and drone recovery in grass.

• Standard M5 hub bore fits traditional 5-inch freestyle motor shafts without adapters.

• Tough polycarbonate construction withstands typical branch strikes and hard landings.
