Radio Control

by Vic Smeed          .

Our model is based on a craft built by the old-established British firm of John A. Thornycroft "Sung a Marutham" is a sleek looking craft which is in regular use by the Customs and Excise Service of Ceylon. Its 58-foot hull is urged along at a top speed of some 20 knots (25 m.p.h.) by twin Thornycroft eight-cylinder diesels ­each developing 275 b.p.h. at 2300 r.p.m. Power is fed to the twin screws through a 2:1 gear reduction unit. The craft is a hard chine type (sharpie) and the prototype's skin is made by double diagonal planking among the equipment on board is a full radar outfit used for night or bad weather interception of shipping. Sporting a royal blue and maroon color scheme, the craft is a handsome and smart ad­dition to any modeller's fleet.

The material was a prime consideration during design. For greatest efficiency and longest life, plywood con­struction is favoured. Since this materi­al is not always easy to find we decided to show construction in balsa. The model in the pictures was a balsa job and built by M. Purday. It is powered by an English E.D .12 diesel and is operated by a pulse radio giving proportional rudder control. Any power plant up to .19 is suitable and we suggest .074 as a minimum.
