Operating principle and design
The KST X20-1035 2BB servo drive belongs to the class of digital HV servos that can operate directly from high-voltage LiPo batteries without additional stabilizers. Featuring a brushless motor, it provides high efficiency, instant response and the ability to withstand long peak loads, which is critical for 3D aerobatics and operation in high vibration environments. Digital technology guarantees high angular resolution and precise positioning of the output shaft.
The aluminum case with milled cooling fins effectively removes excess heat, maintaining stable performance even under the most intense loads. Dual ball bearings minimize output shaft play for precision accuracy. The hardened steel gearbox guarantees shock resistance and durability.
