陈泽熹 陈泽熹 Chen Zexi’s winning aircraft entry from the first MENG modelling contest, Beijing 2014 The Editor was honoured to be invited as part of an international judging panel at MENG’s first model competition held in Beijing back in May as part of Hobby Expo China. Knowing little of the modelling scene in China it was encouraging to see the country which is the driving force behind some of the most exciting kit releases has some very enthusiastic and highly skilled modellers. One such guy is Chen Zexi, the builder of the winning MENG kit in the aircraft catagory.

SHORT S.8 CALCUTTA MODELLED AND DESCRIBED BY MEGAS TSONOS
The uniqueness of this subject led this modeller to a different thinking in relation to the construction that was to follow. First, at a wingspan of 23”, the model had to be robust enough so as to withstand the inevitable mishandlings during its construction. Its sturdiness, when finished, must ensure a long life in the showcase. Second, and more important, the construction had to be designed in a way of leaving an unobstructed cabin interior into which all details would be installed. All the weight of the wings had to be carried by the fuselage skin and not by reinforced bulkheads, as there weren’t any on the real thing… Considering the above, the construction of the Calcutta deviated a little from the traditional scratchbuilding using styrene, as it will be shown in the paragraphs that follow.
4 THE WINGS As usually happens with flying boats drawings, a major design line called “the base line” is drawn below the hull, to serve as a starting point for all measuring and dimensions to be determined. The base line is horizontal, and when looking at the side profile of the drawing, it allows for all design angles, except for the dihedral (which can be seen from the front), to be determined. On the Calcutta (see photo 1), the wings angle of attack is 2.5 degrees (angle a) with the engine nacelles “thrust line” (orange line) set at 0 degrees, that is, parallel to base line (red line). The hull’s top profile (green line) rises at 3.0 degrees (from bow to tail- angle b) so the horizontal stabilizer is set in line with the nacelles thrust line. The result is that the wings are mounted onto the hull at an angle of incidence of 5.5 degrees (angles a+b). With the above in mind I gave priority to the making of the wings; their main 12
