Avia Av-57 (Translated)
The fuselage was all-metal construction. Eight main longerons were shaped as first picture in the text. Main longerons carried loads from wings and undercariage. The others longerons were shaped as second picture in the text. Eleven bulkheads were riveted, the others were made from profiles of shape in third picture.

Pilot's cabin was enterable thru the door from passenger's cabin.
The windshield was made of shatter-proof glass. Side windows could be opened.
Left pilot's seat was adjustable up-down.
Pilot on the right seat operated radio station.
There was an emergency exit on the cabin ceiling.
Wheel controls were dual. Pedal controls were adjustable.
Compressed air brakes was controlled by lever on the steering wheel together with pedal controls (see the photo of A-204, which I sent you earlier - it's the same system).
Stabilizer was controlled by stabilizer control wheel. Two flettner control wheels were placed on rear wall of the cab.
Throttle levers and setting of fuel mixture were under dashboard.
Flaps lever was under throttle levers.
Lever for retracting undercarriage was on the left side of the pilot. Emergency control of undercarriage extension was between pilot seats.
Main undercarriage had oleo-pneumatic shock absorber. Retraction was operated by hydraulic hoist.

Baggage spaces there were placed under the pilot's cabin, behind the toilet and in the wing.
Capacity of rear baggage compartment was 2,3 m3, total capacity of all compartment was 4,14 m3.
Other equipment: navigation lights, two accumulators, radio station, hand-held fire extinguisher, first-aid treatment box, tool kit.
Engine assembly consisted of three Hispano Suiza 9V engines (license of Wright Cyclone 1820-1).
Airscrews Hamilton were in-flight adjustable.

After reading the data listed, it appears that the '57' was a solid airplane, to say the least, and that all of the available technology was implemented into its construction. Vents and heaters for each seat... Nothing was overlooked or ignored and passengers who could afford her luxury were given an exceptional flight experience for the time period. Those big tires, oleo-neumatic gear struts and slow gentle stall speeds most likely provided the softest possible landings for any airliner of its size.

LOL Moses. He probably thinks we all are making plans for his time. He has a lot on his plate. :isadizzy:

Well Gentlemen - here's the story so far:
Still bags of room for those little extra details, blending, highlighting and just generally giving this most worthy subject the attention she really deserves.
Milton has created a spectacular model that just cries out for all we can give her.

WOW!!!
The 57 is looking gorgeous Nigel!
Stunning work guys!
We shall once again be spoiled by your efforts.
Keep your airspeed up,

A few progress shots so far on the Avia 57 textures.
More to come now that the finishing line is within sight.

Fire! Fire! Your pants better not be on fire....
There has been some super serious work gone into this bird by Nigel in sounds and exterior/interior paint. She is a gem. It's a shame the real world version met with such a fate.
The wing fillet looks like the ones I used to draw when I was in grade school. Well, same vintage, so no surprise!

A tad high and a tad hot is better than a tad low and a tad slow - H52
LOL I can relate to that. There are a few people here that know we had to design this aircraft looking at 3 pictures originally. It went through many iterations with several people looking at results.
Fortunately we got a window measurement and was able to scale most things on the fuselage from that. Its one of the toughest things, and rather frustrating, that I have done. In the end it turned out well even with the complicated exit stairs and gear retraction mechanisms. Later, Hurricane91 came up with a few more pictures and that helped finalize the design.
The flight model came together well, the sounds, and now the textures are rockin'. It's great to see it come this far. Thanks to Hurricane91, Nigel, and Oleboy (in the beginning) for their support. Hurricane91's research and contacts were critical to all the Avia projects we have done. Nigel's work has been "top shelf" from the beginning. Thanks guys. :-)
Absolutely.
In fact I believe it's the very mystery that shrouds this unique aircraft that has served us to be that much more creative.
Even its disasterous crash is mysterious, the initial announcement indicating structural failure, but the fact that another Avia crashed within minutes in the same area casts a shadow of doubt on that hypothesis.
Hurricane91 pulled me out of the mud with excellent research work on Czech military markings for the period.
Many thanks Sir.
I fear a second variation of sounds has been devolped while working on the textures - more on that later.

Getting into some enjoyable details on the inner flap/spoiler reccess, I've run some electrical wiring through there too - well it had to go somewhere.

And while I'm there, and as none of the few photos we have clarify this:
Should I take the gamble and metal skin the underwing surfaces between the nacelles?
It seems to make sense.
I'd be grateful for some feedback Gentlemen.
