The Ripmax SD100 is exactly the same servo as the Dymond D47, 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 SD100, like the D47 is a precision 4.7 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 1 Kg.

Another benefit of the SD100 (and D47) is the very low operating current. This increases the flight time of the model by about 40% in comparison to a similar digital servo.
