76" wing span. 50" length. 11" chord. Power .60.
History: Igor I. Sikorsky's S-39 was built to meet the demands of the individual pilot-owner. Following the success of the S-38, Sikorsky felt that a market existed for a smaller amphibian intended for the sportsman and executive. The aircraft had a wing span of 52 feet, a wing area of 350 square feet and a gross weight of 4,000 pounds. The aircraft was capable of carrying one pilot plus four passengers. It sold completely equipped for $20,000. The design of the S-39 started in mid 1929 as a twin engine aircraft powered by British Cirrus "Hermes Mark I" 100 horsepower engines.
First flight was December 24, 1929. On December 30 the aircraft crashed due to lack of power from one engine. The twin engine concept was abandoned in favor of the small Pratt & Whitney 300 horsepower Wasp Jr. engine. First flight was early February 1930 and test pilot Boris Sergievsky commented; "During the first test flight I looped the aircraft." More than twenty-three S-39's were produced in spite of the depression.
The little amphibian established an enviable service record. The "Spirit of Africa", Osa and Martin Johnson's S-39 logged more than 60,000 miles of exploratory flights in Africa. The S-39 established two Aviation World Records, was the first aircraft to use the Pratt & Whitney Wasp Jr. Engine, the first aircraft mounted on a private yacht and the first aircraft designed and produced by Sikorsky after it moved from Long Island to Connecticut.

As of 3/31/07, now redrawn with RC in mind if desired. Other improvements included adding to the perfection of the plan.
Nice little FF or RC flying boat. Twin rudders too! How cool. This is the perfect plane to build just for the joy of building. Could be converted to RC using today's micro radio gear. And economical build and fly too! Wouldn't she look pretty covered in silk and dope? You could use that old engine that is collecting dust and a old wooden prop.
Ya know, if your not living like it was the good ole days,
you might not be living!
35" wing span. 24" length. Power: .049 shown..
The magazine article is included from 1951.
What a neat looking back yard flyer that could be built in an apartment on your dining room table.
The file will print a plan 24" x 44".
The cost to print a plan this small should be about $2.00 with tax included!
File $5.00
Did you check your pulse? And?

Captain Willie Nemo here. I have just return from exploring an uncharted volcanic island in the South Pacific. I was able to make this voyage undetected in a ship that sails the seas "under water" ! I have classified this boat as a Submarine, for which I have christened as the Naughtyless. Although faster than any sea creature including the Giant Squid, it would be nice to fly like the albatross. I was able to capture such a bird late one night while surfaced far out to sea. While at dinner, I made a careful examination of this elegant creature. I made note of the very light wing bones. How the wings where long in length. And how they where thicker near the leading edge and how they tapered back to the trailing edge, while displaying a slight under camber. I noticed that the breast muscles where strong and tasty and where capable of providing enough energy to sustain flight. The tail of the albatross appeared to be able to change the incident of the creature allowing the beast to alter its altitude. And by tilting the tips of its delicious wings, the bird could turn left and right. After dinner, I retired to my study. With pencil in hand, I soon drafted a mechanical flying boat for my own use. Such a craft, with its powerful engine and air screw, would allow me to further my exploration of the South Pacific. Especially the islands of Tahiti for where I have made quite a practice of studding the indigenous natives and there fertility dances.
Hmmm, I hear the natives drums a beating in the Tiki Hut. I think it is ladies night tonight. Time for me to return to my "research". Tonight, my experiment is "how many pina coladas must a native girl consume before I look like Tom Cruise?"
Oh, the burdens I bear in the name of scientific research... Cheers.,,,, Also, I have made these plans available of this flying boat so as to share with others who seek adventure and the joy of flight. She is free flight but could easily be converted to R/C.
This is a high resolution TIFF file containing 200 x 200 dots per inch.
The file will print a plan 36" x 44".
Also included is 3 a page magazine article with a BOM for FREE.
This file has NOT been restored and are being sold "AS IS".
It should be considered as "JUST A COPY".
The following plan will MOST LIKELY show evidence of:
Fold lines, tape, hand writing, damage where the fold lines intersected, specks of ink, fading, blotches of ink, and typical signs of old age and wear.

HISTORY: Republic RC-3 Seabee. The prototype of the Seabee was flown by Republic Aircraft in 1944. Full production did not begin until the end of World War II. Designed and built by the same company as the famous P-47 Thunderbolt fighter of WW II renown, it was the first fully amphibious light or sport aircraft built for private use.
Intended as an everyman's airplane, it sold for $3995 in the beginning of its manufacture, but inevitably the price climbed to $5995 before Republic cancelled production. By that time Republic discovered it was costing twice that much to produce the airplane. I think it is safe to assume that management was not made up of previously gifted students?
Approximately 2500 Seabees were produced.

Hi
Thanks for this deal, the plans look great!
Over the past weeks I've been looking for Seabee stuff like this. My father used to hang around at a long gone local airport when he was a teenager, and used to do odd jobs for a small airline operating a Seabee. So I thought I'd get these printed as a gift for him. Being a modeller, I also recently aquired an unbuilt old Lindberg Seabee from the fifties. Looking forward to building that. And with these plans, doing a bigger one from scratch is possible too!
Again, thanks!
Greetings from Norway!

WING SPAN 46" , CHORD 6.5", LENGTH 37", POWER .10
A nice building project for those who have limited building space, and enjoy float planes. A perfect plane for electric power?
This is a high resolution TIFF file containing 200 x 200 dots per inch.
The file will print a plan 36" x 51".
File $5.00 or 2 gallons of gas! Ya, that's what I thought too.
