note! a new blog site has been  set up solely for Saunders Aircraft at Saunders Aircraft Canada

One can trace the Saunders Aircraft ST-27 narrow fuselage to it's early days, the Saunders Aircraft ST-27 was a conversion of the De Havilland DH114 Heron, and thus retains the fuselage shape lineage of the DeHavilland aircraft before the ST-27.

The DeHavilland Passenger Aircraft Lineage.

The first DeHavilland commercial passenger carrying aircraft was the DH83 Fox Moth, 

The  narrow fuselage Fox Moth fuselage wraps around the four cylinder De Havilland Gypsy Major in line engine.

The De Havilland DH83 Fox Moth first flew in January 1932 and was built using as many DH82 Tiger Moth parts as possible.  The Fox Moth could carry a pilot and four passengers using a DeHavilland Gypsy Major 1C engine of 145 horsepower.

The Dehavilland Fox Moth was followed by the twin engine DeHavilland DH84 Dragon, flown in December of 1932. The Gypsy Major engines were moved to the lower wing and the narrow fuselage carried on. The Dragon carried six passengers plus the pilot.

The DeHavilland Dragon was followed by the DeHavilland DH86 Express - designed for Quantas Airlines, first flown in 1934 with four Gypsy Six engines of 200 horsepower each. The Express carried 10 passengers plus two pilots.

Also flown in 1934 was the DeHavilland DH89 Rapide, a scale down version of the DH86 Express with twin Gypsy Six engines. The Rapide carried a pilot and eight passengers.

During WWII from 1939 to 1945, DeHavilland focuses on military aircraft.

In September of 1945,  the DeHavilland DH104 Dove is flown, the Dove aircraft is completely metal constructed and powered by was the DeHavilland Gypsy Queen engines of 340 to 380 horsepower each and features and retractable undercarriage. The Dove and carry two pilots and eleven passengers. The last DeHavilland Dove was produced in 1968.

The DeHavilland Dove was followed up by the DeHavilland DH114 Heron in May of 1950. The Heron isbasically a scaled up Dove with four Gypsy Queen 30 engines of 250 horsepower each. The Heron carried 17 passengers plus two pilots. The first Heron version Mark I, had fixed gear, followed by the Mark II that had retractable landing gear.

Then in 1968 Saunders Aircraft at Montreal begins conversion of DeHavilland DH114 aircraft by removing the four Gypsy Queen engines and installing a pair of Pratt & Whitney Canada PT-6 turboprop engines and lengthens the Heron fuselage by 8'-6" with two fuselage plugs.

Post # 2 on Saunders Aircraft.

An ON AIR Limited ST-27 C-FCAT  catches fire on the Dryden Airport apron, Sharing these Facebook images and the story from Ray Fread in Dryden, ON.

Ray Fread, a retired bush pilot and AME has written a terrific book: "From Pickle Lake to Paradise"  see this review Pickle Lake to Paradise book review.



In Ray Fread;s words:  " 1977, I show up for work in the Dryden Airport Weather office and see this on the tarmac. This ST-27 had a failed fuel pump. The owner Fritz Meier and his engineer Marty Doyle showed up to change it. Airports closed, it's dark and cold, they are working with a little generator to run a trouble light. Fuel on the tarmac from pulling the pump. As they walk away, wearing heavy boots and parkas, one of them kicks the cord and breaks the trouble light bulb...KABOOM!!!!!! Parts of this plane landed on the runway, hundreds of feet away  "Got so hot the weight of the engine twisted the spar."

note! a new blog site has been  set up solely for Saunders Aircraft at Saunders Aircraft Canada

Saunders Aircraft Canada at Gimli - a short introduction and a request for help.

Saunders ST-28, photographer unknown via the web


In around 1970 the Gov. of Canada announced that "CFB Gimli", the airforce base in Gimli would  close in 1971 as a federal government cost cutting measure.



The Provincial Government of Manitoba looking at offsetting the employment losses from the base closing began seeking alternate industries or businesses to relocate or set up in the Town of  Gimli that had a population of around 2000.

CFB Gimli


One such firm that was offered a Manitoba Government grant to relocate to Gimli was Saunders Aircraft of Montreal, Quebec led by David Saunders.

The 1970 September prov. gov. news release Aircraft Industry Planned for Gimli

Spitfire Mk. IX build from Brian Taylor's 83" ws plans

Spitfire Mk. IX build from Brian Taylor's 83" ws plans. Part 1
Google Brian Taylor Spitfire and you will get many hits - this iconic aero modeller produced and built many warbirds that were scale and flew good.


Plans were acquire used though Sarik Hobbies in the UK sells Brian Taylor plans and accessories though Sariks pricing and shipping is quite high.

Vic RC in the USA offers fiberglass parts and a fiberglass fuselage for the Brian Taylor Spitfire 1/5 scale plans. http://www.vicrc.com/product_spitfire.htm   this where I got the cowl and oil scoop.

I will not be using bellcranks in the wing for the ailerons and separate servos and pushrods for each elevator. My goal is a weekend flying warbird so access  to all control rods and servos is a must.
Zpoxy and 0.60 ounce glass cloth finish with ordinary latex paint.

I will use a DLE 55 engine.

Since I live in Winnipeg, I will most likely paint the Spitfire in RCAF 402 "City of Winnipeg" squadron colours.



I found three good build threads on the BT Spitfire that I will use as as a guide

John Ranson build at https://www.rcscalebuilder.com/forum/forum_posts.asp?TID=10065&KW=spitfire

Ian Daeary's build at https://www.rcscalebuilder.com/forum/forum_posts.asp?TID=15565&KW=spitfire

Edwin's build at https://www.rcscalebuilder.com/forum/forum_posts.asp?TID=22841&KW=spitfire

I've taken what I needed to learn from these three threads and condensed them on Word Pdf, the PDF's are on Google Drive at https://drive.google.com/open?id=18Ku8015_uCORcPBqvXPjXg8_kqHRzkaM

Green Air (Pacific Aeromodel) Tiger Moth

I got a request from a fellow rc modeler from some pics on my arf Green Air Tiger Moth.
 The biplane is:
Specifications
Wing span: 78 in. (1,980 m.m.) Wing area: 1,841 sq.in. (118.8 sq.dm.)
Fuselage length: 65.7 in. (1,670 m.m.) Take-off weight: 10.5-11.5 lbs.(5.0-5.5 kgs.)
Radio required: 4-ch. With 5 servos. Engine: 2C 0.90 cu.in. / 4C 1.20 cu.in.

I've uploaded the kit manual and addendum and some assembed photos to google drive at https://drive.google.com/open?id=1L0nUnDGAUCttE0KzQpHUOQkM_z-JV0J3

I recommend that you do not use the hardware that some with the kit but get good quality hardward from Dubro, Sullivan or Great Planes.

I used the stock swivles on my rigging and the swivels streched up to 4mm after a few flights - causing major slackness in the rigging.
