Scale Aircraft for Free Flight


This book is based upon a compilation of articles by Eric Coates in Aeromodeller from the early 1970s. He was a successful competitor and pathfinder in the development of scale accuracy and these articles remain a leading source of practical advice on how to build and fly a scale model aeroplane.

The major difference between free-flight and radio-controlled scale models is that all the adjustments to the flight path of the former must be made before release:- free flight models must be capable of stable flight, whether under power or on the glide, without the need or the opportunity to carry out in-flight alterations.

This is a challenge most surely met by lightly loaded, slow-flying models based on full size machines having those characteristics, best typified by early bi-planes.

A leading exponent of scale models with this approach was the late Eric Coates. For many years no event for this type of model was complete without his presence; he was a successful competitor & a pathfinder in the development of greater scale accuracy.

His series of articles in Aeromodeller magazine in the early 1970s is still regarded as the classic exposition on the subject, as relevant today as when first written. They offer advice on choice of prototype, construction, covering, finishing and detailing, plus trimming and flying – up to competition standard if required. The articles have been brought together in this book for the first time, updated and revised by technical writer Vic Smeed.

Contents: Introduction; Selection of Prototype; Design Features; Fuselage Construction; Rigging and Wing Attachment; Wing and Tailplane Construction; Covering and Finishing; Detail – Propellers, Engines, Cockpits, Pilots, Guns, Undercarriage, Wheels, Fabric Lacing; Flying; Glossary.
