Torpedo (oz3619)

About this Plan

Torpedo. A 38 inch span Wakefield FF rubber power design from Model Aircraft, June 1950.

Quote: "THIS model is the result of experiments in streamlining which I have been making since 1937, and, as you will see from the plan, the layout differs from that favoured by Copland, Bullock, Chasteneuf and others of that school in that it employs a folding propeller, a lower aspect ratio, elliptical surfaces, a high wing position and a thin, highly cambered aerofoil. A further difference, not evident from the drawing, is that the model is intended to climb fast and high in order to make full use of its exceptional glide. The stability of the design is excellent, showing none of the vices supposedly inherent in streamlined models.

The pre-war versions all had free-wheeling propellers and were relatively light except for thu 1939 Wakefield model. After the war I made the Torpedo, a 1946 Wakefield model, and a FAI job with a slimmer fuselage; all with folding propellers. So I have no hesitation in saying that the design has been well tested and the theories on which it was based are well-founded.

Fuselage The construction of streamlined fuselages has been well covered in the past and there are ample notes on the plan to assist the constructor. It is therefore, only necessary to say that this one is conventional and merely requires care in lining-up the stringers; the selection of good wood to start with, being half the battle..."
