Can't miss this one! Very nice start 👍

Ludvík Kružík
Good to see you, Alec. As you can guess, this is gonna be a big show. There's gonna be a lot of cutting, a lot of editing, and of course, I'll be scratching out new parts. At this point, I'm still planning the build process. But work on the model will soon be in full swing.

very intersting transformation. Following

Ludvík Kružík
Welcome, Pierre, I'm very pleased to see your interest. I hope you find my rebuilding interesting.

The manufacturer of the Avia BH.9 model states 1/48 scale on the box. Actually the model is made in a slightly smaller scale 1/50. I don't mind that in this case. The Avia BH.10 is very similar to the Avia BH.9, but because it is a single-seat aircraft, it is smaller overall than the Avia BH.9. . So even if I build a single seat Avia BH.10 in 1/48 scale, I will be scaling down the fuselage and wing parts from the kit. I have been comparing the fuselage and wing parts to a 1/48 scale drawing of the Avia BH.10 and wondering how to scale the parts down to fit the desired shape and size.

Taking a seat, of course!

Great start! Following👍🏻

Villiers de Vos
A great project.

bughunter
Nice project! The BH-10 will fit nicely between your finished BH-9 and BH-11 👍

Ludvík Kružík
Frank, you make a good point. The Avia BH.10 will add to my collection of Avia BH series monoplanes from the 1920s. They are very interesting and modern aircraft for their time, if only because biplanes dominated the skies at that time.

Ludvík Kružík
I finished modifying the fuselage and wings to 1/48 scale.

Ludvík Kružík
I started making new parts for the model.

bughunter
Successful reshaping of kit parts 👍
Not very much left of the kit, but it looks like that way needs less work compared to a full scratch build.

Ludvík Kružík
That's right. Due to the great similarity of the fuselage and wings of both Avia's, it is easier to modify these parts than to produce completely new ones. Still, there will be a lot of work involved in building the model.
At the moment I have the basic parts roughly ready. I still have to work on them. I will have to do some puttying and sanding. And then fill in all the details.

Alec K
Nice progress. Watch, KP will release their 1/72 kit in 48 just as you finish… 😉 😄

Ludvík Kružík
I'm not really worried about that. Even if it happens, I'm fine with it. Avia BH.10 in 1/72 scale is not very accurate. And if KP goes the route of enlarging parts of the 1/72nd scale model while making a 1/48th scale model (which I think is very likely), it will transfer all the errors of the original model to the new one. Plus, I really like these "crazy" rebuilds. It's a lot of fun for me. 😉

Alec K
I fully agree, scratch builds and conversions are a lot of fun. I'll have to compare the KP kit to drawings before starting mine 👍

Ludvík Kružík
Alec, before building a model you have to choose which machine you want to build. I'm building a first production run machine, but KP's 1/72 scale kit is a second production run machine. Otherwise there were machines with special modifications. And be careful which drawing you want to use. Some drawings are not very accurate (for example the drawing from Modeler 7/1986).
I have described the basic differences between the first and second production series machines in the attached photo.

Alec K
Great, thank you! Do you have a drawing recommendation?

Ludvík Kružík
Alec, you can find a lot of useful information about Avia BH.10 on Czech Modelforum in Pavel Kloucek's overviews.
Information about machines from the first production run can be found here: modelforum.cz/viewtopic.php?f=310&t=143236
And information about the machines of the second production series is here: modelforum.cz/viewtopic.php?f=310&t=143254
A lot of interesting information about the Avia aircraft designed by Benes and Hajn is in this book: nasevojsko.eu/nasevo..onstrukce-Benes-Hajn

I sent you a PM about the drawings.

Alec K
Super, thank you very much.

Ludvík Kružík
I am continuing to build the model by making a new cockpit.

Ludvík Kružík
Unfortunately I only have one period photo of the cockpit, which shows the instrument panel and the right side of the cockpit.
I'm working from the drawing to create the controls and instruments on the left side of the cockpit and floor, with the help of photos of the Avie BH.11 cockpit.
Since the Avie BH.9, 10 and 11 have the same engine and very similar construction, I think most of the cockpit controls were designed very similarly, if not identically.

gorby
Very impressive work so far.

Alec K
Cockpit looks great, those instruments are superb 👍

bughunter
... and the wood looks good too!

Ludvík Kružík
Welcome my friends! Thank you for your interest and popdoru. I really appreciate it.

Ludvík Kružík
I finished the cockpit. After gluing the starboard side to the cockpit, I'll mount the cockpit to the fuselage.

Alec K
Your prop effort beats mine. I tried with sandwitched colored paper infused with resin but needed a painted color overlay. I need to try with correct colored card stock next time.

Ludvík Kružík
Making a propeller out of coloured cardboard was an experiment for me. I wondered if it would work.

Ludvík Kružík
I finished making the cockpit. Now I'm going to glue the bottom of the fuselage and then putty and sand the fuselage.

Ludvík Kružík
It was time to puttying and sanding. We'll see how many times I have to repeat this cycle.

Villiers de Vos
A lot of attention to detail. It will pay off in the end.

bughunter
I will buy shares of putty manufacturers. 😉

Ludvík Kružík
Villiers, welcome! Good to see you again.

This aeroplane is very simple and there are very few small details on it. But the few that are on it, I'll be sure to pay attention to. 😉

Bughunter,
maybe your plan to buy shares in the putty maker will pay off. At least in my case the putty maker made a profit 😄.

I know the fuselage doesn't look good with a heavy coat of putty. But the hull needed that layer of putty on the bow. I had to fill in all the joints and minor unevenness. There won't be much putty left on the hull after sanding, but since the putty shrinks as it dries, it's hard to tell ahead of time where more putty is needed and where maybe not. In this case, more is better.

Ludvík Kružík
The fuselage, wings and tail surfaces are ready for minor detailing. In the end I just needed one rough puttying, sanding, spraying surfacer, one fine puttying of minor defects, sanding again and final surfacer.

Jakub Fiala
Super! 👍

Alec K
Very nice progress 👍

bughunter
The polished surfaces looks great! 👍

TH SCALE MODELS (Thomas Haberl)
Amazing how this turnded out till now Ludvik! Biggest respect for this special project and efforts you make on it. Looking forward to the next steps 🤩

Ludvík Kružík
Mates, thank you all!
It's great to have you on board. Your support means a lot to me.

Ludvík Kružík
After a short vacation I returned to building the Avia. I haven't had much time to build it yet.

I taped the tail surfaces with masking tape so I could spray thin strips of surfacer on the ribs.
To indicate the slight sagging of the canvas on the wing surfaces that were only covered with canvas, I started scraping these surfaces very gently with a round-bladed scalpel. Once I had completed this operation on both wings, it was my turn to cover them with masking tape so that I could spray strips of surfacer on the wing ribs.

I'll add photos of the work in progress next time.

Ludvík Kružík
I started adding details to the fuselage, wings and tail surfaces.
