The KST BLS915 V2 is the successor to the KST BLS915 (V1). Now upgraded to V8.0 and compatible with the Programming Box/USB Link. The KST BLS915 V8 is a top-of-the-line swashplate servo designed for 3D aerobatics. It is extremely robust thanks to its aluminum housing and improved steel gearset. And it offers the following advantages over the BLS815.

Thanks to the more powerful brushless motor and the more efficient electronics, combined with the hardened steel gear, the BLS915 V8 is a cut above the BLS815. The new housing with cooling fins extends the servo’s operating temperature range to 65°C. Thanks to its high response speed combined with the power it delivers, the KST BLS915 V8 HV is very well suited for advanced 3D helicopter pilots. Ideal for helicopters in the 600 to 700 class.
