Available in C4135 and C4140 sizes with three KV options, this fixed-wing motor series is optimized for 16–18 inch propellers. Pair it with a high-pitch propeller for higher top speeds, built for the long-endurance, high-speed missions of fixed-wing RC aircraft.

Thrust and operating time comparison chart

The PLATINUM C4135 250KV, paired with a 16×13 folding propeller, delivers up to 7.25 kg of thrust. Compared with equivalent motors from other brands, it provides 3.5% higher maximum thrust and over 40% longer operating time at maximum thrust.

Versatile Application Compatibility

Tractor

With its standard propeller adapter, the motor supports both tractor and pusher setups, so it fits a wide range of fixed-wing aircraft.

Pusher

Mount it as a pusher on airframes where the propeller sits behind the wing or tail.

Folding propeller

Supports optional high-speed folding propellers, ideal for pusher applications with limited airframe space.

Optimized Heat Dissipation, Continuous Power Output

The rotor bracket pairs rectangular exhaust vents with a centrifugal fan design to reduce airflow resistance and turbulence. This improves heat dissipation by more than 20%, so the motor delivers steady power output over long runs.

Reliable Protection,
Against Complex Flight Environments

Featuring a dust-resistant structure with a steel mesh design, the motor effectively blocks particles ≥1 mm in diameter from entering through the air inlet. It is designed to withstand harsh environments such as dust and rain, meeting the demands of diverse scenarios.

Anti Loosening Protection

Dual anti-loosening protection ensures long-term reliable operation.

Superior Design, Premium Materials

High-performance 0.15 mm low-loss silicon steel sheets reduce iron loss and improve motor efficiency.

A TC4 titanium alloy shaft reduces motor weight while ensuring durability.

220°C high-temperature-resistant enameled wire handles continuous high-load operation.

A three-bearing design enhances motor reliability.
