Hitec HS7954SH G2 Premium HV Super Torque 7.4v

The Hitec HS7954SH G2 Premium HV Super Torque 7.4V (part no. 2220540) is a high‑voltage, high‑torque digital servo designed for demanding control duties. Built around Hitec’s G2 digital circuitry and an HV coreless motor, it combines strong holding power with rapid response, making it a solid choice where precision and durability are essential.

At 7.4V the HS7954SH delivers up to 29.0 kg·cm (403 oz·in) of torque with a swift 0.12s/60° transit time, and 24.0 kg·cm with 0.15s/60° at 6.0V. A heavy‑duty case incorporating an aluminium heat sink, hardened steel gears, and steel gear pins nested in brass axial bushings provides robust mechanical integrity, while dual ball bearings support the output shaft for smooth, consistent operation. Optimised for 2S LiPo systems, it balances speed, strength and longevity.
