Introducing the Avia 51

[Milton Shupe]

Okay, I have now been able to map the exterior and interior in a fog (head cold).

She is ready for the paint shop.

I will focus on the flight model and VC for her next, but ...

Now back to the "51".

[Hurricane91]

I finally got those pesky cockpit windows overhead cut in.

The Avia 156 is looking great Milton. I am suprised that only one was built. I have found very little on the 156 but did verify the Czech registration as OK-AVB.
The three Avia 51s were originaly registered as OK-ABV, OK-ABW, and OK-ABZ.

I am not certain that the 156 ever left prototype status probably due to the war and invasion. I cannot find anything definitive on a production version.

I am still in hopes of finding something on the interior and cockpit. I have dragged my feet on the cockpit design in hopes of some glimpse or hint of the interior.

Thanks for your help.

MY OH MY!!!

My undestanding was that the prototype crashed in 1935. Perhaps the appearance of the Lockheed Orion in Swissair service eclipsed the Avia as it did a number of other aircraft.

Still seaching for anything on these birds. Because of the TX holiday, I will not make it back to the tech library until Friday at the earliest. In the meantime, I will follow up on some leads at couple of modeling sites.

Thanks for all the help and comments; greatly appreciated.

I am trying to make a graphic of the face of the R12 engine ( a 7 cylinder) since a picture cannot be found.

I took the cylinder and housing section from the R17 (a 12 cylinder, same appearance) and mapped it to 1/7th of a cylinder in gmax, then array created a 7-cylinder engine.

Now I need some photoshop help to fill in the gaps.I would also like the graphic to be a little darker as if it were hiding back inside a cowling, and probably more of a monotone.

Attaching the source R-17, an angled view of the RK-12, and the resulting R-12 attempt.

Any takers?

Progress on the "51" side with the exterior mapped, excepting the engine faces of course.

Today, I should finish mapping of the interior cabin.

Cockpit, panel and gauges, and flight model remain.

Milton, I think you could be using far more from the lefthand photo.It certainly looks great quality wise.
The drive-shaft obviously is of no interest if not mistaken.

The 3 top cylinders are in good perspective and seem copy/pastable so it shouldn't be too difficult.

Surely they'll all be rushing to the rescue in a while but, in the event of our many talented texmen overlooking this;
I'll have a bash Chief!


I'd rather they took it on as I'm listening to some serious classical 'music' right now

It looks like you have also cut out the cockpit overhead windows as well. I saw that engine and thought you had located an R 12.
In searching for the Avia powerplant, I looked at many 7 cylinder engines. By comparison, the Jacobs R-755 is very similar to the R 12 and could pinch hit for the Avia.
The center engines exhaust pipes look a bit forward to me. Maybe it's the angle, but you might take a look when you get a chance and see what you think.

Edit: Sorry, I missed the engine work comments above.

[Milton Shupe]

If you have a front-facing picture of the Jacobs, I'll certainly use it. Meanwhile, some additional shots to show where we are on the interior as well.

[Hurricane91]

Wow! That looks great. Silvery.
Meanwhile, here are the Jacobs...

Nail right on the head H!

In my research, I found the two almost identical (sounds similar too).

edit; even the dimensions are similar...copy perhaps?

Good morning, Milton

I would be happy to work your engine graphics if you like. I hope the photo is physically larger. If not, I'll make due.

Oleboy,

The pictures I posted are original size. Once displayed, click to open.

My effort is 838X838. Will be reduced to 512 when done.

Thanks for giving it a go.

Thanks H91, may have to use in a pinch.
