The muscle of the ultra-micro world. At 2.2 grams, this Spektrum linear servo is the control actuator of the micro class — the sliding-arm design that steers small foamies where conventional rotary servos would cost too much weight. This is the high-torque version of the 2.2g family, for the control surfaces that fight the most air, and it ships with its servo mount for a clean installation or a tidy repair.

Fitment

Per Horizon's own compatibility listing, this servo fits the HobbyZone Apprentice STOL S 700mm — both the BNF Basic (HBZ6150) and RTF (HBZ6100). The 2.2g linear family also serves other micro aircraft, but it comes in variants (this high-torque SPMSA203, plus long-throw SPMSA2030L and long-throw-offset SPMSA2030LO) and the right one is position-specific — so for any other airframe, or to confirm which control surface this variant serves on your Apprentice, check the manual's parts list for SPMSA203 before ordering.

Fitting Tip

Micro repairs reward a gentle touch: handle the linkage by the arm rather than the wire, confirm the servo centres before connecting the pushrod, and check control direction and throws in the transmitter after installation — the usual small-aircraft ritual, in miniature.
