KST BLS915 V8.0 Brushless Swashplate Servo

The KST BLS915 V8.0 is a high-performance brushless servo designed for 600–700 class helicopters and demanding 3D aerobatics. With an upgraded brushless motor, powerful electronics, and a hardened steel geartrain, it delivers strong, precise, and reliable swashplate control.

The servo features a durable aluminum housing with integrated cooling fins, helping improve heat dissipation and extending the operating temperature range up to 65°C. This makes the BLS915 V8.0 well suited for high-load helicopter applications where consistent performance is essential.

The V8.0 version also supports programming via a programming box or USB link, allowing users to configure and fine-tune servo parameters to match their setup.

With its combination of brushless power, hardened steel gears, aluminum cooling housing, and programmable functions, the BLS915 V8.0 is built for pilots who demand high-speed, high-load, and precise swashplate control.
