HACKING A SERVO

Hacking Servo

This page is going to describe how to take a R/C servo and make it into an excellent gearhead motor. The changes are quite easy to do, once you have seen the insides. This modification is known to work quite well on Futaba S-148 servos, which are commonly available. But before beginning make sure that you know how servo motor works.

AERO-MODELLING SERVO

SERVO

A Servo is a small device that has an output shaft. This shaft can be positioned to specific angular positions by sending the servo a coded signal. As long as the coded signal exists on the input line, the servo will maintain the angular position of the shaft. As the coded signal changes, the angular position of the shaft changes. In practice, servos are used in radio controlled airplanes to position control surfaces like the elevators and rudders. They are also used in radio controlled cars, puppets, and of course, robots.

TYPES OF AEROMODELS

Aeromodels can be basically classified into 2 types:

• Static and
• Flying

Static model aircrafts are not intended to fly. They are commonly built using plastic detail parts, photo etched brass, and wire, though other materials such as wood, metal, and paper are also often used. Some static models are scaled for use in wind tunnels, where the data acquired is used to aid the design of full scale aircraft.
