HS-7954SH High Voltage Ultra Torque Ball Bearing Steel Gear Digital Standard Servo from Hitec - HRC37954S

The HS-7954SH could be considered the most economical high voltage, high torque, coreless servo on the market.  Based on the ultra popular HS-7955TG has the added benefit of a high voltage coreless motor.  With 403 inch-ounces of torque at 7.4 volts, the HS-7954SH is fast too with a 0.12 second transit time when operating on a 2 cell LiPo pack.  The HS-7954SH harnesses all this power is by utilizing a heavy duty case that incorporates an aluminum heat sink, hardened steel gears, two strong steel gear pins nested in brass axial bushings.  Put it all together and you get one tough high voltage servo at a price that can't be beat.

What is a coreless motor?

A conventional servo motor has a steel core armature wrapped with wire that spins inside the magnets. In a coreless design, the armature uses a wire mesh that forms a cup that spins around the outside of the magnet. This arrangement is much lighter resulting in smoother operation and faster response time.
