An interview with Mike Patey describing the changes he made to his Wilga to create his Draco.

https://www.youtube.com/watch?v=PqhI4MeCn1c



A series of 20 videos of Mike Patey going through the design and very hands on build process of creating Draco. This series could be called "Airplane Improvement" and he does a great job of explaning and showing step by step how he did far more than just go from piston to turbine power. He also has one heck of a man cave.

Click on the link and then click on "Draco Build" to start the playlist: https://www.youtube.com/channel/UCSvdee86uThqIrloZjWwNVg/playlists

A few additions in the Light Aircraft section ... Unbuilt and Built conversions including those Wilgas and Lancairs, but also DHC Beavers and Otter and Legends.

This is only a “Fantasy” project, but it is interesting to consider.



The “PBY-7AT” amphibian aircraft concept is based on the proven design of the classic rugged PBY Catalina flying-boat. A PBY airframe would be entirely stripped, redesigned and rebuilt for exploration, bush-flying and circumnavigation. The end result would be a complete rebirth of the aircraft, bringing this classic flying-boat up to 21st century standards.

This conversion project is based on 1) the fact that “SuperCat” and “Bird Innovator” variants of the PBY aircraft have historically proved to be successful and viable conversions of the type to high-power engines and 2) the fact that the Basler BT-67 conversion to this type of turboprop was successfully achieved in the past (The DC-3/C-47 and the PBY-5A being originally equipped with the same Twin Wasp family of engines).

Among others, the following modifications are planned:

- 2x Pratt & Whitney Canada PT6A-67R with Hartzell 5 Blade Aluminum propellers.
- 75-Inch fuselage extension (10%, 1,9 m.) forward of pylon.
- Complete cockpit retrofit with Garmin G1000.
- Row44 worldwide broadband internet.
- Single-pilot certified.
- Improved STOL performance. VFR/IFR/Known Ice certification.
- Improved low-level, low-speed handling and maneuverability with BLCs.
- Redesigned wing enhancing aerodynamic and structural performance. Composite control surfaces.
- Landing gear refit/optimization for bush/rough terrain.
- “Tall-tail” redesign if applicable (cf. PBY-6A/PBN1 Nomad).
- Excellent sound-proofing and insulation of the cabin to cope with extreme weather conditions.
- No pressurization.
- Redesigned hull for better performance on water (V-hull "Clipper" bow, redesigned steps, etc.)(cf. PBN1 Nomad).
- Addition of the rear observation blisters if absent.
- Addition of the “airstairs” access door if absent. Bulkheads overhaul.
- “yacht” cabin, with berths, galley, toilet/shower, workstations etc., fit for long-range travel exploration (cf. Bird Innovator).
- Standard Airworthiness Certificate: Certified for 9 passengers (11 counting pilot & copilot).
- Increased fuel tank capacity. Auxiliary wing tanks mounts. Transcontinental ferry range: 2,500 nm.
- “zero accumulated fatigue damage” certification if poss. (cf. Basler BT-67)

Fokker Turbo-Triplane being considered.

IMVHO, no we should not put a turbine in a Fokker triplane. With their light weight they might be able to take an electric motor so will that be next? Just my ten pence worth.

December 10, 2019, Harbour Air test flew an electric powered DHC-2 Beaver on floats. magniX provided the electric motor and other electrical components. They only plan to test fly a single Beaver prototype, but their long-term goal is an electric conversion kit for Cessna 208 Caravan. Harbour Air operates the largest fleet of floatplanes (Cessna 208 Caravan, DHC-2 Beaver, DHC-3 Single Otter and DHC-6 Twin Otter) in North America. Most of their routes carry passengers from Vancouver harbour to Victoria harbour or Nanaimo harbour or Seattle harbour, etc. Most legs are less than one hour.

I presume this advertiser's what-if would date from around the time of the F.Mk.8? Possibly an F.Mk.4 airframe I guess, but the larger F.8 tail would have been handy with the turboprops.
Interestingly there is an article on the Trent-Meteor in Air Britain's magazine this month, they show the advert Joe posted but trimmed to only show the aircraft!

I flew in a Saunders ST-27 from Montreal to Ottawa during the early 1980s. The ride was similar to a Beechcraft King Air. Remember that Beechcraft introduced the stretched 99 to compete in the exact same market (19 seater commuter). Beechcraft still sells dozens of Model 1900 commuter planes every year.
I also saw the remnants of Saunders Corp. when I jumped at Gimli in 1992. Misc. incomplete fuselages and spare parts littered an RCAF-surplus hangar.
