The Ripmax SD150 is exactly the same servo as the Dymond D60, and is rated for up to 9.6V operation. This allows it to be used with a 2S LiPo receiver battery without a voltage regulator, reducing cost and increasing reliability - and allowing useful rx battery voltage info to be transmitted back to the pilot when using modern telemetry radios.

The Ripmax SD150, like the D60 is a precision 9 g analogue servo with a good torque and excellent centring. It has a low backlash geartrain and can be used for all control surfaces. Suitable for models weighing up to 2 Kg.

Another benefit of the SD150 (and D60) is the very low operating current. This increases the flight time of the model by about 40% in comparison to a similar digital servo.
