BM5320S 1.7g Ultra Micro Nano Digital Servo JST-SH 1.00mm pitch
The BM5320S digital servo is super tiny, lightweight, and ideal for small RC planes.
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.
