Overview
The MKS Aluminium HV777A+ is a high-voltage, standard-sized, coreless servo built for extreme performance. Boasting incredible torque, blazing-fast speed, and a robust metal gear train, it's designed for the most demanding RC applications, such as 1/8 scale buggies and truggies, helicopters and planes. This servo is waterproof for all-weather conditions and features a 25T servo horn for precise control.
Note
Servos are powered by the ESC's output to the receiver. If you're using a higher-strength servo than the ESC can support (usually greater than 20kg), you may experience 'brown-outs' where the radio signal can be interrupted and cause erratic driving. This can be helped by plugging a Glitch Buster into the receiver smoothing the current delivery. However, in some cases, you may need to install an external BEC.
