The machine is a staggered biplane, with large gap and very small bottom plane. As to the outward appearance, this is shown in the general arrangement drawings and photograph given herewith, and it will be seen that the machine is, for a biplane, of extremely pleasing and graceful lines.
That it is the result of the most painstaking work in detail design will be obvious, and literally not one ounce of unnecessary weight has been allowed to remain in the structure. How this very low figure for structure weight has been attained will, it is hoped, emerge from the following description. Assuming that the engine weighs roughly 100 lbs., the machine itself weighs only about 270 lbs., which is extraordinarily light. The weight empty - i.e., complete with engine, but without pilot, passenger, petrol and oil - is only 373 lbs. So much is this the case that the two Hawker machines will be the lightest of all those taking part in the competitions. The old Sopwith firm had a reputation for light construction, and it is significant that the same characteristics are to be found in the two light biplanes. Hawker Engineering Co., Ltd., of Kingston-on-Thames, considerable interest attaches to the two machines that have been entered by this firm for the Lympne competitions. 14 AND 15)Īs the first light 'plane to be designed and built by the H.
