Hitec Servo

These are some of Hitec servos that I looked at:

Size Speed

(Time/60° (s))

Torque (Kg.cm) Price


Bang per buck (Torque/Time/Price)
HS-475HB Standard 0.23 4.4 15 1.3
HS-645MG Standard 0.24 7.7 34 0.9
HS-985MG Standard 0.16 9.6 58 1.0
HS-755HB 1/4 0.28 11.0 25 1.6
HS-805BB Mega 1/4 0.19 19.8 34 3.1


Micro 0.17 3.6 41 0.5


Standard 0.23 10.3 48 0.9

For standard size analog servo, the HS-985MG performs best. It is based on a coreless motor. It provides the highest torque as well as the fastest speed.

The HS-475HB is the best value servo. It has the advantage of using Karbonite (just like kryptonite 🙂 ) gears. Karbonite is supposed to be stronger than nylon but has less wear and tear compared to metal.

The HS-645MG has good torque compromise without being overly expensive. It uses mostly metal gear.

For a mega 1/4 scale servo. The HS-805BB looks awesome.
