Granville Miller & Delackner R6H “Quod Erat Demonstratum” – 1:72 scratch
April 24, 2015 in Aviation
Hi! This is my next Macrobertson plane, this time the ill-fated last “true” GeeBee the R6H QED. For whose not familiar with the type (I thinkis not a suprise) the story in short:
“The Gee Bee Q.E.D. (“Quod Erat Demonstrandum”), aka Gee Bee R-6H, aka the “Conquistador del Cielo” (Sky Conqueror) was the last in a series of racing and touring aircraft from the Granville Brothers. Unlike the other famous Gee Bee aircraft, the Q.E.D had the distinction of never finishing a race it was entered in. The Gee Bee Q.E.D. was started by the Granville Brothers in 1933 prior to their October bankruptcy. On 11 February 1934, “Grannie Granville” died in Spartanburg, South Carolina delivering a Sportster E used to finance a new company based in New York and called Granville, Miller & De Lackner. The R-6H (Q.E.D.) was completed later in 1934 for customer Floyd B. Odlum, with Jacqueline Cochran chosen as the pilot. The touring aircraft was designed with large fuel tanks to compete in the MacRobertson Air Race from RAF Mildenhall in East Anglia to Flemington Racecourse, Melbourne. A Curtiss Conqueror was the specified engine, but a Pratt & Whitney Hornet was substituted to make the race delivery date. The Gee Bee Q.E.D. shares the same general shape as the Gee Bee R1 racer, but is nearly 10 ft (3.0 m) larger in span and length. The aircraft was powered by a 675 hp (503 kW) Pratt & Whitney R-1690 Hornet. The fuselage is steel tube with fabric covering. The wings used wooden spars and ribs with mahogany plywood covering. The aircraft was painted bright green with orange markings to match the sponsor “Lucky Strike” cigarettes.”
Well curretly isn’ a kit out there about the R6H (and good plans neither) so I drawed my plans based on photos and started to squared off the parts – fuselage from balsa wood wings are from plastic sheets. I smoothed the surfaces and replicated the “rough” parts from resin and made further adjustments on them. At this stage I began to think about a small serie because at least I wanted to build two QEDs – Sarabia’s “Conquistador Del Cielo” it’s pure art deco painting is a must 🙂 . Finally all little parts and bits finished and I could begin the building – prior to it I assembled a prototype wthout any filler or paint just to be sure my “kit” is buildable at least. If anyone doesn’t try scratchbuilding an entire subject may won’t know how many small and fiddly bits have to produce for a completed project. This wasn’t a short project either. Finally I made assembly instructions and painting guides for my homemade decals, some “box art” and voila 🙂
