Today I continued with other modifications to the fuselage Avia Bh.11

Alec K
Nice! Co se dimenzí týće, z čeho vychaziš? Máš nějaké plány?

Ludvík Kružík
Thanks Alec!
Ano, mám výkresy z L+K, z mofeláře a z knihy Václava Němečka - Československá letadla I. Pokud se týká velikosti, měla obě letdla stejné rozměry. Největší rozdíl mezi BH.9 a BH.11 je ve tvaru přídě. Avia BH.9 měla oválnou motorovou přepážku a tím i zkulatější tvar přídě (po 2. trupovou přepážku. Avia BH.11 dostala kvůli zjednodušení výroby obdélníkovou motorovou přepážku, takže její trup včetně přídě je celý až k motorové přepážce hranatý. Avia BH.9 měla většín podvozková kola než BH.11 a pozdější serie BH.11 měla křídla s ostřejší náběžnou hranou. Jedno místné úpravy u obou strojů vznikly zakrytím předního pilotního prostoru a jeho využitím pro insatalci další palivové nádrže. Navíc u BH.11 existuje mnoho speciálních verzí, které se konstručně v mnohém liší od základní vojenské verze.

Díky moc za info. To se bude hodit až se do nich pustím s 1:72.

Ta trupová modifikace se ti skutečně moc povedla. Klobouk dolů 👍

Rádo se stalo.

Kdybys potřeboval podklady, až to budeš stavět, mohu Ti to, co mám k dispozici poslat.

Gorgeous work on that cockpit interior 👍
8 November 2021, 13:45
Robert Podkoński
I agree with Alec here - terrific work!

Ludvík Kružík
Gentlemen, thank you very much for your kind words.
I decided to make a new cockpit because the parts in the kit are too rough and most of the cockpit equipment is missing. And the second reason was that I was enlarging the model to a scale of 1:48 and the few parts that were usable are small (because they are in a scale of 1:50).

Michael Kohl
It is a bit insane what you are doing here, but I like it. Go ahead. Cut the fuselage another time, no?! 😜
9 November 2021, 20:03
Ludvík Kružík
Yes, it may be a little crazy, but I enjoy it ... And that's what it's all about. 🙂
9 November 2021, 22:25
Ludvík Kružík
After a short break, I continued to work on the fuselage of the Avia BH.9 today. Now it's time for sandpaper and putty.
12 November 2021, 21:35
Alec K
Nice precision on that cockpit installation 👍
13 November 2021, 13:00
Ludvík Kružík
Thanks! This is the advantage of a cockpit tailored to the model. 🙂
13 November 2021, 15:59
Ludvík Kružík
After a short break, I continue to build models by producing a cockpits for Aivi BH.11 🙂
22 November 2021, 11:07
Ludvík Kružík
A small step forward in working on the model.
30 November 2021, 19:03
Alec K
Nice progress Ludvíku 👍
1 December 2021, 14:34
Ludvík Kružík
Thanks Alec 🙂

Work continues on the cockpit of the Avia BH.11
4 December 2021, 01:04
Ludvík Kružík
The cockpit for the Avia BH.11 is ready.
7 December 2021, 22:41
Alec K
It's coming along nicely. I have to try that sliding cockpit install technique someday 👍
8 December 2021, 13:51
Ludvík Kružík
For Alec K:
Thanks!

This technique has its advantages. When manufacturing the cockpit outside the fuselage, the individual parts for assembling the cockpit are more accessible. However, it is necessary to work precisely so that after inserting the finished cockpit into the fuselage, there are no gaps between the cockpit and the fuselage.
8 December 2021, 16:29
Alec K
Agreed. I imagine the added sidewall thickness is of concern as well (at least for me in 1/72 scale).
8 December 2021, 19:51
Ludvík Kružík
I make the side walls of the cockpit from a plastic foil 0.13 mm thick. This is comparable to the thickness of office paper. Both sides of the cockpit made of this thin foil narrow the cockpit by 0.26 mm. At 1/48 scale, this difference is negligible. I no longer build 1/72 scale models. But I think that even on this scale, the narrowing of the cockpit by 0.26 mm should not bother you too much.
8 December 2021, 21:35
Alec K
Hmm, that is probably true. Thanks for the info 👍
9 December 2021, 14:09
Ludvík Kružík
You're welcome. If I can, I will help. 😄 😄 😄
9 December 2021, 20:55
Ludvík Kružík
Little progress in construction ... Avia BH.9 and BH.11 fuselages and wings received the first surfacer spray.
14 December 2021, 16:24
Alec K
The droop in the canvas on those wings is superb 👍
15 December 2021, 04:03
Ludvík Kružík
Work continues in the new year. I started assembling the engine for the Avia BH.9
6 January 2022, 21:03
Ludvík Kružík
I finally made time for Avia. After completing the partial assembly, I sprayed the assembled fuselage and wings with primer.
17 January 2022, 21:51
Alec K
Superb progress Ludvíku. It's indeed nice when the wigs can be added 👍. The scratched fittings on top of the fuselage are really nice 👍
18 January 2022, 00:52
Ludvík Kružík
Thanks!
I'm very curious what it will look like when the paint is sprayed on it 🙂
18 January 2022, 14:48
Alec K
It will be a beaut 👍 😄
18 January 2022, 15:08
Ludvík Kružík
I hope you are right 🙂
18 January 2022, 15:20
Ludvík Kružík
Today I sprayed a camouflage scheme on the Avia model. I'm a little closer to the goal again
😄
18 January 2022, 23:15
Robert Podkoński
Looks perfect! I would not believe that you have enlarged the original parts, if I haven't seen this here, Ludvik. And all these hinges... fantastic!
19 January 2022, 05:50
bughunter
What a carnage! That are the most correct Avias ever built in 1:48 👍
19 January 2022, 06:56
Ludvík Kružík
Thank you Robert for your kind words of praise. I really appreciate it.
19 January 2022, 09:23
Ludvík Kružík
bughunter, that's a really big compliment! Thank you very much!
19 January 2022, 11:15
Alec K
Colors look great! I'll have to compare your paint color mixes with mine (I sneaked a peek at your build thread on Modelforum).
19 January 2022, 13:20
Ludvík Kružík
Hi Alec, if you try to mix colors on Avia (or another Czechoslovak aircraft from this time with four-color camouflage), I think the brown color could be a little darker. I would try to change the mentioned ratio of brown colors to 60% H37 and 40% H47.
19 January 2022, 18:50
Ludvík Kružík
After a small retreat, I continue to build the model. According to the photos, I found that the hinges on the Avia's bow I made too big. All that was left was to remove the large hinges and make new ones. It was extra work, but I thought it paid off.
After this small inconvenience and the restoration of the damaged aircraft bow paint, I applied decals to the model.
22 January 2022, 12:58
bughunter
With your enlarged fuselage you have enough space for the decals 👍 Looks like they are to big otherwise?
25 January 2022, 21:05
Ludvík Kružík
Yes, the decals in the kit are larger than the scale of the kit (1:50). It's the manufacturer's fault. The decals correspond more to a scale of 1:48. It helped me. I'm glad I don't have to deal with making new decals.
Anyone who wants to build this model without modifications will have a problem with the size of the decals. The decals are likely to fit at least approximately on the wings and tail surfaces. But the matriculation letters on the sides of the fuselage are too large for a 1:50 scale.
25 January 2022, 21:56
Ludvík Kružík
Avia Bh.9 machine No. 11 was special for long-haul flights. Compared to serial machines, it has been modified. One of these modifications was the addition of an aerodynamic engine cover. Because the kit does not contain this cover, I had to make it.
29 January 2022, 20:25
Alec K
Nice work on that engine cone 👍
30 January 2022, 03:59
Ludvík Kružík
Thanks 🙂
The engine cover is not ready yet. The photo shows the condition of the cover after making all the holes. I tried to put the cover on the engine. Now I'm going to finish the surface of the cover so I can spray it with paint.
31 January 2022, 12:45
Ludvík Kružík
I'm finishing the engine slowly.
1 February 2022, 22:58
Ludvík Kružík
I received new documents and photos for the Avia BH.9 L-BONG. While studying this new information, I discovered that the Avia BH.9.11 (L-BONG) had different wings. Unlike serial machines, this Avia carried more fuel and engine oil. The added tanks and their fillings meant extra weight. That's why this Avia got new longer wings with a different profile and a larger bearing area.
For me, this means dropping already finished wings and building new wings of the right shape. Too bad I didn't get this information before. I would have less work to do with the production of the model 🙁
What can be done ... again and better 🙂
6 February 2022, 17:55
Robert Podkoński
Keep calm and carry on, Ludvik! (it is a piece of cake for you, I am sure 😉 )
6 February 2022, 18:39
Alec K
Not a great news, but surmountable 👍
6 February 2022, 18:47
Ludvík Kružík
Friends, thank you for your encouragement. The production of new wings will prolong the construction of the model, but it is nothing that cannot be done. The good news is that the original wings will still find application. I will use them for the Avia BH.11 which I am building in parallel with this model.
6 February 2022, 20:49
Ludvík Kružík
The production of new wings continues successfully. I have the base of one wing ready, now I will produce the second wing.
19 February 2022, 11:07
Ludvík Kružík
Production of new wings is coming to an end. The lower surfaces are already sprayed with camouflage silver paint. Now I'm preparing masks for spraying the upper surfaces of the wings.
9 March 2022, 18:52
Alec K
Very nicely done. Those wings are a model unto itself 👍
10 March 2022, 12:44
Ludvík Kružík
When building the wings, I was inspired by modelers who build flying models. And I also looked at how real wings were made in Avia. I kept the way the wings were made. I just used a different material. 😄
11 March 2022, 11:09
Alec K
It sure turned out well. The engine looks super good also 👍
11 March 2022, 14:02
Guillaume Blanchet
Very interesting model. Watching
11 March 2022, 15:30
Ludvík Kružík
Thanks a lot! I'm glad you like it. 🙂
11 March 2022, 16:15
Ludvík Kružík
The new wings are ready 🙂
18 March 2022, 22:13
Alec K
The wings are back 👍 🙂

Impressive work!
19 March 2022, 09:34
Ludvík Kružík
Friends, thank you very much for your kind comments!
21 March 2022, 22:06
Ludvík Kružík
I continue to build the model. I started making chassis and small parts.
24 March 2022, 11:16
Ludvík Kružík
I refilled the tanks necks and caps on Avia's bow ... and made a new speedometer.
24 March 2022, 20:08
Alec K
Those details are great Ludvíku 👍
25 March 2022, 12:33
Ludvík Kružík
Thank you, Alec.
Now I'm working on more details. I glued to the model of the wing strut and now I am dealing with the placement of small instruments (revmeter, Venturi tube) and small tubes on the bow. I will add more photos soon.
27 March 2022, 12:32
Robert Podkoński
Thanks to you, Ludvik, I am now aware that one can make a masterpiece out of a simple kit of a simple (at first sight) plane. You're a master of detail!
27 March 2022, 13:33
Ludvík Kružík
Robert, thank you. Even though I think you are exaggerating, I must admit that I am very pleased 🙂
Even on simple aircrafts, there are many interesting details. However, not every kit manufacturer can produce them all (sometimes it is not even technically possible). In my opinion, it is these small details that greatly contribute to the better appearance of the model. That's why I like old and simple kits. It's an opportunity for me to improve and learn something new.
27 March 2022, 20:22
Robert Podkoński
Certainly, Ludvik. Especially when these are so skillfully recreated as yours.
27 March 2022, 20:43
Ludvík Kružík
According to the photos, I added other small details to the Avia's bow.
27 March 2022, 20:52
Alec K
Looks like this will no longer be a simple build after I dive into my 1/72 scale interpretation 🤔
28 March 2022, 13:11
Ludvík Kružík
Alec, it's up to you.
28 March 2022, 14:23
Ludvík Kružík
Again, a little closer to completing the model. I added exhausts to the engine and glued the propeller, and I added rudder control cables to the stern of the aircraft.
30 March 2022, 21:17
Gordon Sørensen
Fantastic detail and construction photos, Ludvik! The amount of effort you have put in definitely shows with the excellent results!
17 April 2022, 12:06
Ludvík Kružík
Thanks Gordon, I'm glad you like my building. I really appreciate it. 🙂

Avia BH-9 is completed. More photos in a separate album: KLuK
17 April 2022, 20:51

Album info

Although the Avia BH.9 kit looks like a novelty, the opposite is true. In the box you will find old parts of Avia BH-11 from Smer in 1:50 scale. Only one Trees with fuselage and Avia BH-9 wheels is really new.

I will build the Avii BH.9 as a single-seater version, which (among other things) became famous in August 1925 for a continuous flight (without a stopover) on the route Prague - Paris - Prague.

And since my collection is all in 1:48 scale, I decided to adjust this model to this scale.
