The MKS HV9780 is a chrome-titanium gear high-voltage tail mini servo with aluminum case, recommended for 500 class helicopter tail rotor applications. Running on 5.5–8.4V (2S LiPo unregulated) at 760μs/560Hz, it delivers 62.4 oz/in (4.5 kg/cm) at 8.2V with a 0.040 sec/60° transit speed — providing fast, precise tail authority in a compact 38g mini servo package.
A coreless motor delivers instant response and precise centering. Chrome-titanium alloy gears provide precision and durability under the sustained high-frequency inputs of tail rotor operation. Dual ball bearings ensure smooth, consistent output shaft operation run after run. The aluminum case adds rigidity and heat dissipation.
