Overview
The Hitec HS-648MG is a high-torque metal-gear analog sport servo featuring the industry-standard 25-tooth output spline with 3mm hex screw. Built as the 25T version of Hitec's powerful HS-645MG, it's a perfect choice for larger sport planes, monster trucks, and buggies that demand durable, high-torque performance at a sensible price.
Equipped with Hitec's unique M/P (Metal/Plastic) first gear technology and one of the strongest gear trains available in any servo, the HS-648MG delivers 9.6 kgf-cm / 133.32 oz-in of stall torque at 6V with a 0.20 sec/60° transit. Dual ball bearings and an IP4X-rated case round out a servo built to take a beating.
