Design and development

The Hawk Major was a variant of the Miles M.2 Hawk, developed by F.G. Miles to take advantage of the new inverted de Havilland Gipsy Major engine. Other changes included metal (instead of wood) engine mounts and streamlined undercarriage. The prototype M.2F Hawk Major) was first flown in 1934 and went on to second place in the 1934 King's Cup Race at an average speed of 147.78 mph. A racing version was developed as the one-off single-seat M.2E Gipsy Six Hawk with a 200 hp de Havilland Gipsy Six engine. The production Hawk Major had the 130 hp de Havilland Gipsy Major engine. The aircraft sold well to private owners, including two that were fitted with smoke generators to allow them to be used as skywriters. An improved version (the M.2H) with a trailing edge flap replaced the M.2F on the production line. A number of special one-off racing versions were also built.[1] In October 1934, Squadron Leader Malcolm Charles McGregor flew a Hawk Major from RAF Mildenhall to Melbourne, Australia in 7 days, 15 hours while competing in the MacRobertson Air Race.[2][3] In 1936 Miles Hawk Speed Six, G-ADOD was entered into the Schlesinger Race from Portsmouth to Johannesburg and flown by A. E. Clouston who nearly made it all the way to Johannesburg but had to make a crash landing due to engine trouble 150 miles south of Salisbury.[1]

In 1935, an improved version for training use was developed as the Miles Hawk Trainer.

gollark: Pretty sure anything below 2.125, which 2.1249 is, should round to 2.12.
gollark: If you don't want the images and stuff it's only 15-ish gigabytes.

gollark: The equation is 4FeS2 + 11O2 --> 2Fe2O3 + 8SO2. You want to know how many moles O2 are needed per mole FeS2, so that's 11/4 = 2.75. Then, since the question asks for how many moles O2 are needed with *3* moles FeS2, multiply by 3, and you get 8.25.
gollark: The answer is just (3/4)*11 then, which is 8.25.
