These servos are designed to work on the voltage range from a single LiPo cell (3V - 4.2V). Most have a specified maximum working voltage of 5V; some customers report that they work OK on 5V, but this cannot be guaranteed. If you want to use them on a 5V system (e.g. BEC output from 2S ESC), then a power silicon diode (e.g. IN4001) should be used in the positive lead from BEC to receiver/servos to drop the voltage to approximately 4.3V.

An ultra micro rotary output servo for use on single LiPo cell R/C systems. Weighs 2.0gm complete with output disk, wires and connector.

Supplied with 3 types of output arm: single, double & cross. The single arm is 8.5mm from centre of pivot to the end of the arm, the double arm is 10mm from centre of pivot and 20mm overall diameter, the cross arm is 14mm in diameter and 7mm in radius.

Available with JST-SH (1mm), Molex Picoblade (1.25mm) and JST-ZH (1.5mm) connectors, all on 100mm leads.
