It is necessary to enlarge the fuselage to a scale of 1:48
1) extend the hull by 5 mm
2) increase the width of the hull by 1 mm
3) increase the height of the hull by 1 mm
First, I increased the width of the fuselage by gluing a 1 mm thick plastic foil between the halves of the fuselage.

2) increase the width of the hull by 1 mm
3) increase the height of the hull by 1 mm
First, I increased the width of the fuselage by gluing a 1 mm thick plastic foil between the halves of the fuselage.
In the cockpit area, I cut out excess material from a glued plastic plate.
After adjusting the cockpit space, I glued the halves of the fuselage together.
To extend the fuselage, I cut off the bow of the aircraft before the first cockpit. I glued a 2 mm thick plastic plate to the bow of the fuselage.
After the glue dried, I removed the excess material with a micro-grinder.
I glued the extended bow back to the fuselage.
The hull now has the correct width and length. The last operation remains, increasing the height of the fuselage.
To increase the height of the fuselage, I cut the fuselage horizontally into two parts.
I glued a 1 mm plastic plate to the lower part of the fuselage.
In the cockpit area, I removed excess material with a micro-grinder.
A comparison with the plan revealed an inaccurate shape of the cockpit openings.
I cut off part of the fuselage with inaccurate holes in the cockpit. I will make this new part.
I glued the top and bottom of the fuselage together.
The fuselage now has the correct dimensions in all three axes.
I made a new upper fuselage from thin plastic plates.

To enlarge the wing to a scale of 1:48, I glued a 1 mm thick plastic plate between the upper and lower part of the wing. I glued pieces of plates from above and below to the protruding plate at the end of the wing to equalize the thickness of the elongated wing ends.
After grinding the wings into the correct shape, several sealing and grinding followed. Then I sprayed the ports, sprayed the whole wings with a surfacer.
I made new tail surfaces from a mm thick plastic plate and sprayed ports on them.

I engraved covers and panels on the fuselage.
I engraved covers and panels on the fuselage and added footrests to the side of the fuselage.
I sprayed the fuselage and wings with white primer.
The national emblems on the decals are light colors. That's why I didn't use the decals. I sprayed the national emblems on the model and thanks to that I was able to use slightly darker colors. (So far, the wings are attached only to the fuselage.)
I sprayed the fuselage and wings with white primer.
For comparison - on the left is a decal, on the right is an inscription sprayed on the wing.
In the photo, the difference between the decal and the spray-painted emblem is not so great, but in reality the difference is even greater.

I sprayed camouflage paints on the wings. After retouching minor bugs, the wings will be ready for mounting to the fuselage.
The fuselage and tail surfaces are sprayed with silver paint from below. Ocher and green fields are sprayed on the upper surfaces. Now I have to disguise the fuselage and spray the last (brown) color.

I sprayed all the camouflage colors on the fuselage.
The main parts of the aircraft are ready. The wings are attached to the fuselage. At this point, the wings would interfere with the completion of the fuselage.

I found that the selected color scheme is fictional and does not correspond to any real machine. Therefore, I repainted the Avia, this time according to the actual aircraft B.11.3.

The Avia BH-11 had the same engine as the Avia BH-9 - a five-cylinder Walter NZ-60 star engine. As with the Avia BH-9, I will use a Brengun engine casting for this Avia. Engine casting is a small kit in itself. It contains 18 castings and 18 photo-etched parts on a metal plate. The remaining 10 valve rods need to be made of 0.5 mm wire.
I started by gluing the individual cylinders to the engine housing.
After gluing the cylinders, I painted the engine. Now I will gradually glue small parts to the engine (intake and exhaust pipes, valve rods and rockers, cables for spark plugs ...). Most of these parts are really small, so the work will be slow.
I glued the intake manifold to the back of the engine.
I glued a wire to each cylinder on which I stick the valve rockers.
I made the valve rockers and their rods from thin wire.
After straightening the wire and cutting it to the correct length, I glued the new rocker arms with rods to the engine.
I drilled 0.3 mm holes in each engine cylinder. I glued thin wires into the drilled holes.
To illustrate the spark plugs, I threaded thin plastic tubes on the wires.
I dyed, shortened, and shaped the wires to look like spark plug cables.
I dyed, shortened, and shaped the wires to look like spark plug cables.
To get an idea of the size of the engine, I photographed the engine with a coin. The coin has a diameter of 20 mm.
I added a carburetor to the engine.
I prepared the parts for the landing gear and wing struts.
I glued thin wires into the landing gear parts and wing struts.
I made a new venturi from the rest of the resin. The part from the kit is unusable.
I made a new tail skid out of wire. First, I hammered the wire to make it square. Then I tapped the end of the wire to make it as thin as possible. And I shaped the thin part into the skid shoe.
I made a speedometer out of a plastic log, pieces of wire and a decal with the face of the instrument. I used a thin wire for the venturi holder.
I painted both instruments black.
I drilled holes in the fuselage and glued the speedometer and venturi into them.
I added a bovden to the tachometer according to the photos.
I painted the firewall silver and then glued the engine to the bow.
The engine is almost finished, only the exhausts are missing.
I added leather backrests to both cockpits.
I drilled holes in the fuselage for the wing pins. In the photo the wings are just mounted without gluing. I'll glue the wings when I have the struts done. The struts will help me keep the wings in the correct position.

I glued the wings to the fuselage and used a cardboard jig to fix the correct position of the wings and fuselage.
I drilled holes in the wings and fuselage with a 0.4 mm drill bit. I glued the struts into the drilled holes.
I made the thin tubes that run from the pitot tube to the fuselage out of thin wire that I painted black. Finally, I glued everything to the wing strut.

I made the wind shields for both cockpits from acetate foil.
Avia already has its own chassis.
I glued the finished wind shields, finished a few details...
... and the Avia BH-11 is ready. 🙂

Because the construction of the Avia BH-9 was ultimately more demanding than originally expected, I abandoned the intention to build the BH-9 and BH-11 at the same time and suspended the construction of this Avia until the completion of the Avia BH-9 model. Now the Avia BH-9 is complete, so I return to this model and will work to complete it.

To Kyle DeHart:
Thank you for your interest!
To Alec K:
Welcome Alec, nice to see you again. Although there will be some modifications to the Avia BH-11 (otherwise I can't even build my models 🙂), but compared to the Avia BH-9, there will be slightly less modifications. This Avia will be a completely normal serial machine. So I don't have to make special equipment and new wings 🙂

Exactly. I have the original finished wings left from the construction of the BH-9 model. Now I will use them for this model and I have less work to do.

As always, new information will appear when it is too late. Only after finishing the coloring did I find out that the color scheme of the Bk.11.17 machine is fictional and does not correspond to any real machine. That's why I decided to change the color. The new color scheme corresponds to the actual aircraft with number B.11.3

I started working on the engine. The engine is completely exposed and clearly visible on this machine. At 1:48 scale, the engine is really small and its installation with all the little things requires a lot of patience and time.

The engine is almost complete. Only the exhaust pipe is missing. But I'll stick it when the engine is mounted on the fuselage. Now the exhausts would just interfere and I would probably break them when mounting the engine on the fuselage.

My tail skid production technique came about because I am comfortable. Therefore, I was looking for a simple and quick method for making it. 😄

Bruce, thank you for your admiration. But it's not as hard as it looks. It just takes a little thought and skill... and a little courage to do things differently. 🙂

Album info
I originally started building this model together with the Avia BH-9. However, because the construction of the BH-9 gradually became a demanding reconstruction, I decided to build each aircraft separately.
Some photographs from the beginning of the construction still capture the process from the period of joint construction of both models.
