Sikorsky S.42 Flying Boat questions...

[Randy_Cain]

Hi,

I'm trying to get started on a boat and need some help..all ready.

So far, I've been able to determine that the S.42, 42A, and 42B had 2 different wingspans and up to 3 variants of the Hornit engine. So far, I have the 118' winspan for the S.42. What was the span for 42A and/or B?

On another point, the props. I can't find anyone that has any details on prop type, shape or diameter. I only know they had 3 blades each.

Any info would be greatly appreciated! ;D I know several of you know a LOT more places to look than I do. Any links would REALLY help.

Thanks in advance,

Hi Randy,

Forgive my ignorance here I'm just trying to help, in the aircraft.cfg is that information accurate or is it just a rough guide, it mentions wing span and props etc?

I'll post more links here as I get hold of them

There are some remarks with ref to the following three links which will help to identify different versions/MKs

Hi Colin,

One little problem with that. I don't know of anyone that's built one. Do know of one for FS9?

To date, this is the most comprehensive site I've found for flight characteristics and development.

www.sikorskyarchives.com/s42.html

As for the general specifications, they are available from the usual sites, (Wikipedia, etc.) only I'm not always certain what version of the plane I'm looking at, depending on the site.

Yours,


P.S. Thanks, Adrian!
;D

I'm not 100% but I think I have one very similar, give me a few minutes and I'll check.
I recently got a new PC so all my old stuff is on disks, I'll have a look through them for you.

[Randy_Cain]

Hi Colin,

I think I can give a point in the right direction in your library. ..the Sikorsky S.43 by Bill and Lynn Lyons, known also as the JRS-1 (the Mini-Clipper). It was used by Pan American Airways, the InterIsland Airways, as well as others..and, of course, the US NAVY.

Yours,

I found this which I use as an AI type, it isn't your aircraft but very similar, it's a Dornier X



I also have a Sikorsky VS44 if that's any use.

Hi Randy,

the link provided by Adrian at airminded.net gives a 114 ft span for the plain S-42 and the longer 118 ft span for both the A and B version.

Bill Lyons also has AI S-42's doing touch-and-go's at Dinner Key, Miami, in his Golden Wings package.

Personally, I wouldn't want to use the Do X - it looks different enough to me, and it is a kind of high-key aircraft.

Best regards,
Volker

At a later stage flaps were fitted.

Hop this helps,

Also the S42 used the same engine and props as the S43 but 4 of 'em instead of just the 2 used on the S43. Discovered that when researching the S43.

[Randy_Cain]

Thanks so much, guys! ;D

Now, if I can only figure out the "best" way to do this. Here's what I have for a propeller, so far....along with my rendition of the Hornet engine.



With the tip from Willy, I went back the S-43 .air file and grabbed what Bill Lyons used for prop specifications.

I hope this is close. Any suggestions would be greatly appreciated.

Yours,


P.S. Adrain, you posted a link above that we can't use. There's just a box that says, "Remote Linking Forbidden"- yadayadayada. Could you figure out a different way to get us there?

[Tom/CalClassic]

Hi Randy,

That forbidden photo is in the link just under it ("mmm, forbidden photo...").

Hope this helps,
