Injora is beefing up its micro servo catalogue with the INJS2065 PRO, listed on 21 August 2026. In the 2065 format, this high-voltage digital servo targets 1/24 and 1/18 crawlers, two scales where tight packaging and moisture quickly put electronics in trouble.

The INJS2065 PRO micro servo in numbers

Injora‘s spec sheet claims a stall torque of 7.93 kg.cm (110.1 oz.in) at 7.4 V, rising to 9.00 kg.cm (125.0 oz.in) at 8.4 V. Speed follows the same logic: 0.069 s/60° at 7.4 V and 0.061 s/60° at 8.4 V. The accepted supply range runs from 4.8 to 8.4 V, which allows both a direct 2S LiPo installation and a conventional regulated supply.

The rest of the specification: aluminium alloy and nylon case, cored motor, fully stainless steel gear train, waterproof design, PWM signal, 180° travel over a 500 to 2500 µs range, 5.9 mm 25-tooth spline and a 250 mm JR-type lead in 26 AWG. Dimensions stay contained at 23 × 13 × 25.9 mm. Two nylon servo horns are supplied with the servo.

Three ready-to-fit versions

Beyond the bare servo, Injora offers the INJS2065 PRO as complete kits with a mount and horn matched to a specific chassis: a version for the 1/24 Axial SCX24, a version for the 1/18 Traxxas TRX4M, and a version for the Redcat Ascent-18. It is the brand’s usual approach, sparing the modeller from separately sourcing a servo mount with the right hole spacing.

Price

The servo on its own is listed at 24.99 dollars. The sets with mount and horn go up to 34.99 dollars for the SCX24 and TRX4M versions, and 35.99 dollars for the Redcat Ascent-18 version. Aggressive positioning for a waterproof servo rated at 9 kg.cm in this format.
