BM5320S 1.7g Ultra Micro Nano Digital Servo JST-SH 1.00mm pitch Micro RC 5320 Product Description: The BM5320S digital servo is super tiny, lightweight, and ideal for small RC planes. Features: These are advertised as a 1.7g sized servo, that does not include the wire and plug. Most of them I have weighed are around 1.9g complete but no control horn. These come with a 4" lead (110mm) with the micro JST-SH 1.00mm pitch connector that fits many receivers. These come with the standard X-arm, T-arm, single arm, and mounting screws. These are low voltage servos intended for single cell use only, but seem to work fine at 5v. Please note the polarity of the JST SH micro connector.
