These four pictures begin a project that should result in one of the largest models I have ever attempted. Not the biggest - the 1:32 Liberator holds my record here - but close!
However, the impressively large box contains surprisingly little and, also surprisingly, large components such as the fuselage, wings and tailplane are already assembled. Incidentally, these are made of fibreglass and require their own treatment.
These parts are also stable and clean. A bit of filling was required, as the traces of glue and filler on the seams are very rough and show air pockets. This will now be sanded, the cockpit sawn out and the windows drilled - well, modelling a little differently than usual! 🙂

The panel lines look ok I guess. I mean, I would be happy with those panel lines.

Mr D
Like it , nice project.
I'm working on the Beriev Be-6 Armoured Flying boat,
Revisiting a kit after 33yrs.
All the best with yours...😃👍👍

Robert Podkoński
A true behemoth it is. I will surely follow this build with utmost interest!

Looking forward to seeing this take shape. 🙂
I believe the last Mars had it's final flight two weeks ago.

BTW. Do we see the finished Fairchild in the background, Roland?

Roland Sachsenhofer
I am very happy about all your interest! In fact, I also started this project because of its topicality; the pictures of the last flight of Hawai Mars are always a heart-warming pleasure; this one in particular, thanks Gorby for posting it!

Today I drilled the openings for the windows in the fuselage; I determined the diameter of the holes from kit glass parts. They seem a bit big to me, but we'll see. As I'm not going to use the clear parts from the kit, but want to make them with Klearfix, I could reduce the diameter quite a bit.
The next steps will be to finish sanding the fuselage seams - now only the top side has to be done - and then to glue the wings and stabilisers to the fuselage. To do this, I'm cutting solid steel rods to length, which I'll glue in place with a two-component adhesive.
The Mars should be ready by mid-October: I want to take it to the Euromodel in Ried, Upper Austria.

And yes, In fact, the more or less finished Fairchild F.91 had to serve as a scale model in the background! 🙂

Du bist echt eine Bau-Maschine, Roland! Und immer kommt etwas sehr schönes raus! 👍

Roland Sachsenhofer
Danke für die Einschätzung, Thomas! 🙂

Roland Sachsenhofer
The construction of Mars is progressing: I'll show you a few construction steps in a little 'time lapse'. Attaching the wings and tailplane with 2k glue worked well; the materials could be sanded smooth and fine afterwards. However, the brittleness of the fibreglass caused some difficulties; parts kept splintering off and had to be filled, sanded and re-engraved. As I always do the whole thing standing up, wearing a mask and under running water, this always turns into an almost athletic exercise 🙂 But now it seems to be over and the Mars is ready for its first encounter with colour... I took the two crew members under the cockpit canopy to make the proportions clear and to keep my options open for presenting the finished aircraft - who knows, maybe it will take off or fly?

gorby
It's a bit of a monster! 😮
Doesn't look like an easy build but you seem to be beating it into shape. 🙂

Robert Podkoński
You're the brave man, Roland, not me...

DerMattes
Das schau ich mir weiter an 🙂

Mr D
Looking good Roland 👌
Be a nice bird when she done, pilots look smart 👍👍

Cuajete
Wow... an unusual and gigant model... It seems like fiberglass is difficult to handle.
Great job so far, Roland!

Michael Kohl
Na, da hab ich doch auch nen Blick drauf

Roland Sachsenhofer
Thank you very much for your motivating feedback and your interest, mates!

Łukasz Gliński
I have to follow that behemoth 👍 I don't think I'll ever find enough space to build one myself 😄

Thomas Kolb
My goodness, your models are just getting bigger and bigger! I cannot wait to see it finished!

Finn
Looking interesting, I'm in

Ray Loch
Following as well. Just saw its retirement flyby and landing in Pat Bay, Its Huge.

Roland Sachsenhofer
Fortunately, the Martin Mars has reached the stage where the colouring and surface design will be the main thing; so far I've been 'plugging holes' again and again: the fibreglass surface proves to be quite brittle, damage is difficult to putty, and when re-engraving the lost panel lines it quickly happens that it cracks again under the carefully guided scalpel blade - and a new hole has already appeared. The new pictures show a few such construction sites, for example at the bow under the cockpit glazing or on the back of the fuselage between the wings.
But, all in all, in retrospect it's all half as bad, now I'm looking forward to the paintwork!

Thank you, mates, for your interest and feedback! Ray, I would have liked to have experienced that too!

Cuajete
Roland, I was unaware of these problems with fiberglass and it is a shame that these kits are so expensive considering the quality of these materials. I think the worst is over. You can feel proud of the work done so far. The effort was worth it. Go on!

Roland Sachsenhofer
Those are encouraging responses, yes, Cuajete, I think so too. Thank you both for your interest and comments!

Mr D
How big is the model??
Is it cast in fiberglass because it's to big for injection molding??
Nice to see the update 😁👍👍
The vent in behind the cockpit done now.

Mirko Römer
That's what you call a project!👍

Nicolas
Cool project, following.

Roland Sachsenhofer
Thank you friends! The Mars as a 72 model measures 84.5cm in wingspan and has a length of 48.5cm: huge, but not so huge that it couldn't have been made into an injection moulded model. The B-24 Liberator from Hobby Boss in 1:32 that I built this spring, for example, was significantly larger and yet still injection moulded.

What is now proving to be a challenging issue is that the acrylic paint I used does not seem to want to adhere properly to some parts of the resin fuselage and wing panels, even though I have meticulously and accurately cleaned the surfaces. And another thing: after I sprayed a first coat of white paint on the fuselage today, something became apparent that hadn't appeared before: the resin surfaces are covered with small air pockets, i.e. holes.... 'Much enemy, much honour' as they say in German! 🙂

Ben M
What are you using for primer? I almost always use tamiya spray primer as it usually adheres even to challenging surfaces. I have had trouble occasionally on some resin surfaces where I've resorted to krylon plastic compatible spray paint as a primer.

Roland Sachsenhofer
That's a good question, thanks for the tips: I used glossy black acrylic paint here as usual - it actually looked quite good until yesterday, after a few days drying time, I started to mask off the black areas on the undersides of the wings....
I think I'll just carry on with Gunze and Tamiya acrylic paints - and touch up where necessary.

Roland Sachsenhofer
Der aktuelle Zustand der Mars in Weiß hat noch nichts mit der finalen Oberseiten-Farbe zu tun, sondern bildet nur die Basis für das Rot der Unterseiten. Aktuell erstrahlt die Mars sogar in leuchtend Gelb: Dies sollte die Leucht- und Deckkraft des folgenden Rot noch weiter stärken. Der Aufwand wird allerdings dadaurch erhöht, dass immer wieder Spachtel- Schleif und Gravierbedarf auftaucht: die Resin Oberflächen sind äußerst uneben und voller kleiner Lufteinschlüsse, ein echter Jammer. Aber ich bin zuversichtlich, dass mit der steigenden Stärke der Lackschichten auch die raue Oberfläche etwas mehr Geschlossenheit zeigen wird!

Mr D
It's come along way 👌👍👍

Łukasz Gliński
Oh man, that is bigly yuge indeed 😄

Cuajete
You're doing very well, Roland. Don't be discouraged.
Kopf hoch! 👍

Roland Sachsenhofer
Sapperlot! I only wrote the text in German yesterday: here it is in English:
The current state of the Mars in white has nothing to do with the final upper side colour, but only forms the basis for the red of the undersides. At the moment, the Mars is even shining in bright yellow: this should further enhance the luminosity and opacity of the red colour to follow. However, the effort is increased by the fact that there is always a need for filling, sanding and engraving: the resin surfaces are extremely uneven and full of small air pockets, a real shame. But I'm confident that as the thickness of the paint layers increases, the rough surface will also show a little more unity!

Thank you very much for your encouragement and motivation! Yesterday I mentioned that Mars has now been coloured yellow as the last stage before the red - here are the pictures!

Cuajete
👌

Roland Sachsenhofer
Thank you Cuajete!
....and now in red! It's getting really exciting for me now. Not just the question of how I'll manage the masking for the white upper sides, but above all whether the colour under the adhesive strips will stay on them or - hopefully - on the model when I peel them off!

Cuajete
I'm sure it does, Roland. That Mars looks great and the red color looks great.
Is the stand underneath included in the kit?

Roland Sachsenhofer
Thank you! Yes, that's him. Doesn't necessarily look much, but is very useful when building

Mr D
Hi Roland 👋.
Is it heavy? Being fiberglass ?
I've read about the difficulty you had with Glass resin!
My dad used to make parts for race bikes ....and air bubbles very hard to avoid! Also cutting against the grain....tends to pull other strands.
Your getting to a better stage now and it's coming on nicely now...
I thought it was the Goose at first glance.. earlier in build.
Good luck with rest.👍👍

Arseny K.
I just love it! Respect

Roland Sachsenhofer
Thank you both! Somehow it is really comforting and above all interesting that I am not alone with the problems with the fibreglass surfaces! Yes, the construction is fairly heavy, but above all it needs enough 'air space' above the workbenches when it is swivelled to get everywhere with the airbrush! 🙂
Well, the 'Spruce Goose' is still a dream - but one with a chance of realisation!

Roland Sachsenhofer
The time has come! Now the layers of paint under the masking have to prove that they can adhere to the fibreglass surface and want.... prognoses say it will all be possible! In the meantime, the white has been applied to the surfaces, which definitely looks good on the Martin Mars.

Cuajete
Great, Roland! 👍

Roland Sachsenhofer
Thank you for encouragement!
I would like to show you the condition of the Martin Mars this morning: The red and white areas survived the masking quite well, only small areas had to be touched up with brush strokes, but the black areas on the undersides of the surfaces, on the other hand, remained generously on the adhesive tape. I masked them again straight away - I now trusted the red areas surrounding them - and sprayed over the black, applying a first coat of glossy clear varnish over everything in the same session. Now I have to break up the red and white edges on the fuselage with a cloth, well, the white always builds up beautifully... Maybe I can try out the decals tomorrow!

Agnius
Interesting project! Following

Zbynek Honzik
It looks spectacular, Roland! Fingers crossed and looking forward to seeing the result. 👍

Cuajete
I agree with Zbynek Honzik 👍

Mr D
Very nice 👌
The hard work is being rewarded now 😁👍👍

Roland Sachsenhofer
Thank you very much for your encouragement and motivation - much appreciated! I'm all the more pleased to be able to show you the Martin Mars with decals! The decal material was anything but easy to apply and in some parts - with the red stripes - it broke into numerous stripes, but I'm all the more pleased to be able to show you the pictures of a reasonably well-marked Martin Mars! The engines and floats have been under construction for some time now and will soon complete the Martin Mars as it approaches the finish line.

Cuajete
Looks really great, Roland! 👍

Roland Sachsenhofer
Thank you Cuajete!

Nick Dragone
Excellent job ! The same plane is on the cover of the November 2024 edition of Fly Past Magazine. Fabulous work Roland

Mr D
Looks great 👍👍 hard work paying off 👌👍

Roland Sachsenhofer
ank you very much, Nick and Mr D! It's really quite inspiring to have a 'current' aircraft in the works. 🙂
I would like to show you a few current pictures of the Mars - the completion of which is slowly coming into sight. The surface qualities such as colour scheme and gloss level have been determined, the windows are in progress. One on the left side of the fuselage is still missing and the two small windows at the very front of the bow are so cracked by the drilling - the fibreglass material has its pitfalls - that I have to think of an alternative. Perhaps they will be finished with a decal.

Neuling
