All,

 

I've been looking at the miles speed six for my next project using the phil kent plans. The plans quote 1/4 @ 86" however the fullsize has a wing span of 33 feet making 1/4 scale 99" can anyone shed some light which is correct...???

 

Cheers

 

Dave

After a quick hunt, the 33ft wing is quoted for the Miles Hawk Major........IIRC, the Speed 6 was based on this basic design, but obviously intended for racing. I've never looked into it too much, but was the standard wing clipped a little for racing hence a shorter span maybe?

Phil

Hello There:

 I would appear that two versions where developed the original M.2E derived from the Hawk Major
 with a 33 ft. span and later the one derived from the Sparrow Hawk. In this version the center section
was removed and the outer wing attached to the side of the Fuse.

That head on line drawing is not correct for the Speed 6 (I thought only 1 was built?)......it has no 'flat' centre section with the landing gear. The only flat section of wing is that under the fuz....the dihedral is from the fuz side outwards.

Wiki's take on things:

Looks like the different Mk's are just engine and seat configs .... Interesting guess I could go and measure the full size then I'd know for sure.


Design and development[edit]

The Hawk Major was designed as a successor to the Miles Hawk by F.G. Miles. Main changes were a de Havilland Gipsy III engine, metal (instead of wood) engine mount, and trousered undercarriage. The prototype (designated 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 Mildenhall, England to Melbourne, Australia in 7 days, 15 hours while competing in the MacRobertson Air Race.[2] In 1936 Miles Hawk VI, 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 forced crash landing due to engine trouble 150 miles south of Salisbury.[3]
In 1935 an improved version for training use was developed as the Miles Hawk Trainer.
