| Utilizing blind rivet construction and common
high grade aircraft aluminum the builder can easily assemble the
Darling in as little as 400 hours.
The design will be offered in the form of A-B
partial kits, full kits and fast finish type airframes. Smaller
canopies can be purchased for shorter pilots, the one shown
accommodates a 6'4" 200 lb.
The manufactured components in the kit provided to
the builder include all the machined parts,
TIG welded 4130 assemblies, pre-formed leading edge radius skins,
pre-bent spars / stringers etc. All the skin patterns are traced on
the raw sheet stock and all the necessary hardware, rivets and other
fittings are provided.
Pre-formed fuel tank, landing gear legs and
fiberglass cowling are also provided in addition to a very complete
assembly manual.
The Power
The Darling can be flown with a
minimum of 40hp and up to 60hp! This is a Rotax 447 fan cooled
installation! Partial to full kits could be made available including
a fast build option! John Harvey is at the controls below he is
6'4" 170 lb.'s. In the photo you can see the rollover structure
which comes as a standard feature.
The Darling utilizes twin Mikuni
Super VM floatless carburetors to maintain a clean aerodynamic
cowling exterior. The Darling can utilize air-cooled two or
four-stroke power plants in the 40 to 60 hp range. Pictured above is
the Rotax 447 fan cooled installation being ground run.
The ideal power plant would be the HKS 700E.
This is what it will look like if
a retract version was available! My personal favorite.
This aircraft was designed and fabricated by John
Harvey in fifteen weeks. John's background is in R&D, production
engineering and industrial design with the emphasis in
conceptualization. Prior to this project John's company, ETI,
provided design development engineering and tooling services for
LoPresti Speed Merchants' new Howl Cowl design, Velocity's new Elite
door system, and Fillet fairings, weldments, tanks and other details
on Jim Stewart's scale S-51 Mustang.
John's background in experimental aviation dates
back to the Polywagon in the late 70's. Prior to being full time
with ETI in '93, John worked within Bombardier Sea-Doo's design
group providing direction in vehicle dynamics and systems
integration for their personal watercraft products since its
inception in 1987.
