The DS90DLHV is a high voltage (HV) digital servo built on a tough hybrid case of aluminum and plastic. Equipped with dual ball bearings and all-metal gears (for durability), it outputs 90 oz-in (+5 pounds of force) and has a transit time of 0.165sec/60° - it's what's called a standard-size servo. Standard size means it fits most .40-1.20 remote control model airplanes.

It's our opinion - this servo is the yardstick against which you objectively measure others in its class because it's sealed with 13 o-rings, has bronze hardpoints reinforcing the case, offers the superior cooling and strength of an aluminum center, and is held together with Allen head fasteners. So good it alters your perception of everything in its class with respect to value.
