Introducing the Avia 51

Looking good OleBoy!

That photo Milton posted and this one are the only photos I have ever seen of the 57.

Also found a neat period photo of a Avia trade show display.

Oleboy, excellent work! That looks great. :applause:

Moses, eeewwww! That picture helps alot. Can see the wing tips, ailerons, not sure about flaps there ... if that is all aileron or flap included.

Wheels do look large and I look forward to getting that strange retraction animation done.

Thanks for this one ... a real helpful gift to the project! :applause:
 
Excellent work Moses. Those are great shots. I would love to see someones collection of the photos displayed at that display!

Milton, I think I have the perfect tire texture to use. Let me know when you get to that point.
 
ok it mentions flaps equal to the span between engines, split type, so they probably run engine to engine with a split where the centre of the fuselage is on the underside only.....

just my thought as it mentions words to that effect....

It appears from Moses' photo that there is a degree (or ten :icon_lol:) of dihedral to the outer panels. The center section appear near 'flat' so Matt's guess looks pretty accurate (similar to the DC-3). Split flaps were often simple with only 1 or two intermediate stops in extension so 3-positions would be typical. Ailerons appear to be 3/4 of span of outer panels (less the tips)

At first I thought the rib-like bit at the wing panel joint was just that ( a joint cap ala DC-3) but the more I look at it, it seems to be a track standing slightly proud of the wing which is the guide for the V-strut of the gear to move along during retraction... ie. the gear pivots at the top of the main struts and is pulled backward by the V-strut to retract aft of the nacelles.

Also interesting to see the tailwheel faired fore and aft of the wheel

You are "right on" regarding the retraction mechanism. ;-)

And I suspect you are both correct regarding the flaps.

This gives me some things to go on. I appreciate your insight. :applause::applause:

I just put my maps down to take 5...It took 25, but boy, oh boy was it worth it just to get a gawk at this...:jump::applause::salute:

If I spot any difference between your version Sir and the official 'Avia', I'm keeping it to myself, as there's no way I'd want to be associated with spoiling a single curve on that beautiful creation.

THIS IS the 'official model' in my books!

:running: I can hear the awesome thunder of engines rrrrrroaring...:jump: just wait till I get out of this traffic jam...you'll see...:wiggle:

Does this mean that you volunteer to do the sounds? :)

After doing more research, I've come to the conclusion that the Savoia Marchetti SM 73 is the Av57's kin. The shapes are so much alike.

Lots of pictures. http://www.google.com/search?q=praž....,cf.osb&fp=687dbb61086f72be&biw=1759&bih=731

The front of the aircraft does. After the cockpit it appears to change shape dramatically. I've noticed that the Fokker F7 types are very similar too
 
Beautiful aircraft the SM73 for sure. :) It's much more classy IMO.

Is that available for download somewhere?

Stefano Meneghini did a nice one. Look for s73_v20.zip at Flightsim (I can't ever seem to get a link to work). There is also an update. Stephano also did the S.81 and Fiat G.12 as well. All are wonderfull and the instruments or gorgeous.

Thank you; will check it out! :jump:

And thanks OB.
 
Another great tri-motor is Manuele Villa's excellent SM 79. Many versions and paints, including one with a Corsa livery.
 
Avia 57: Finished the wing work (fairing, wing thickness and dihedral), added the flaps, and now ready for some main gear work. :)

I also have the cabin and cockpit floor in, the separating panels for the cockpit and cabin and navigator or galley area, and have the passenger door animated.

I would like your thoughts on the cabin appointments. Similar to the Avia 51 or more austere?
 
Interesting that Nebessar seemed to have a 'trademark' approach to engine mounts. Like the Type 51, the Type 57 wing-mounted engines had a thrustline angled down compared to the center one which seemed to be online with the fuselage ref. line. It's quite noticeable in the "Flight" photo.

Also, when it comes to the 'details' phase Milton, there seems to be a small single eyebrow bump for an intake at the top front of each cowl. Letting my squinty old eyes squint a bit more, it appears to just be a formed bump with an extended induction tube mounted to the engine, not a full "scoop".

Wish there were more pics as the wing fairing looks huge and rather unusual in the first photo (left side view) - indeed like a separate piece grafted on
