AZ (ex Heller) Potez 540 - engine gondola question

[Roman Schilhart]

Dear fellow Britmodellers,

can someone explain to me, what these two bars running along the outside of the engine gondolas, are good for?

Here they are, already pre-shaded:

 

 

Any information is welcome.

it's the mouting to fit the flare bomb shackles. Two flares, Michelin BEC 1933, are mounted in line.

EDIT: there were two flares on each outer side engine nacelle

and at the rear tip of port gondola, there were two pyrotechnic lights(Holts)

Alright, that explains why the AZ/Heller kit has those rods/bars on the outer sides of both gondolas.

What would be the technical term for this shackles (if there is any specific designation)?

Or is it simply called "the mouting to fit the flare bomb shackles"?

Thanks so much for your assistance, BS_w - informations about this aircraft type are hard to come by!

Greetings from Vienna,

support engin éclairant: parachute flare  mount
blue: lugs
green : electrical wire (jrelease control)
red: sway braces
yellow : pyrotechnic lightings, seems like a tin can hanged in a stirrup.

As you work on the Potez, i remember that the aileron is eleven millimeters too short,.
it misses 3 mm at inner side and 8 mm at outer side.
another problem is the number of the wing ribs is too high but it's not easy to modify it

BS_w@ Beautiful pic, what's the source? Any book? Thanks for answer!

Thanks for pointing this out.

Since I have no conclusive reference material I will not be able to make any modifications to the kit.

Rather treat it as a "classic build" with all its pros and cons.

I contemplated about reducing the fabric-sag effect on the wings but left them as is;

Correcting the number of wing ribs seems impossible without eliminating virtually all surface detail.

From "notice descriptive et d'utilisation de l'avion Potez 540"

@Roman Schilhart I came across your post by chance, and was wondering exactly the same - I'm building the same kit at the moment. This bit appeared to feature on some 540s but not all, and isn't in the callouts for my particular scheme so I left them off and filled the holes. In the original Heller instructions they're referred to as support(s) d'engin, but there's no mention of éclairant. Thanks for the clarification.

 

(I too am wondering if I should try to do something about that exaggerated ribbing on the wings... they seem to numerous and too deep...)

Roman, how did you detail the wheel wells of your Potez? I can't find any reference regarding wheel wells interior of this plane.

Roman and Marko , did you found this page? 

https://aviation-ancienne.forumactif.com/t7856-potez-54-derives

There are some photos of machines under construction showing structures of insides.

 

Some insight from bottom is available on photos from SCW demolished Potez published her https://www.sas1946.com/main/index.php?topic=27891.0

But below is structure of gondola of developed from Potez 540 passenger/transport machine Potez 62/65. It was a bit shorter in rear part due as in cases of radial engines variants of 540 family, but surely the structure in wheel bay must be the same.
