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.

Covering the Aeromodel

Covering the Model

TWO COLOR COVERING

The introduction of heat-shrinkable plastic covering has saved a lot of labor and time for many modelers. Plastic coverings require far less effort and skill than the silk and dope or silkspan and dope coverings of the past. A tight, glossy, attractive covering job can be achieved by anyone with the right tools and a little patience.
