Situation update from TikkakoskiSunnuntai 14.12.2025 - Reino Myllymäki ja Mika Rautasaari This blog post is based on the photo delivery from Tikkakoski by Jorma Laakkonen on 22 November 2025 and the Myrsky project update provided by Mika Rautasaari / Finnish Air Force Museum on 10 December 2025.
On the fuselage work is ongoing to produce the engine cowlings. After the drawing showing the latest development version of the so-called engine shroud plate was discovered in Tikkakoski, the task of manufacturing this plate was transferred from the Aviation Museum Society’s Tuesday Club Myrsky team to the Finnish Air Force Museum’s restoration team. The lower section of the shroud plate was made in Vantaa by the Myrsky team but, joining the lower and upper sections may still result in changes to the lower part as well.
The production of the engine cowlings has begun by making different wooden moulds for the engine cowlings and the air intake duct. Manufacturing of the sheet metal and stiffener parts for the engine cowlings, as well as the air intake duct itself, has also started, along with the fabrication of the flame tubes.
When the Myrsky’s wing was transferred to Tikkakoski, the undercarriage was fitted with patterned tyres used on the Vihuri. Now Dunlop tyres resembling the originals have been found for MY-14. These have previously been used on a Smolik training aircraft and it is likely that these tyres have fewer layers of fabric than the original Myrsky tyres. One of the tyres broke at the side during inflation and will be repaired, as the tyres are intended to be used only for exhibition purposes and will not be pressurised. Vihuri tyres will be fitted on when moving the aircraft. The undercarriage struts have been painted with a mixture of Isotrol paint and aluminium powder, which is intended to imitate the original cadmium-plated surface. The undercarriage and wheel well doors have been test-fitted, but further adjustment is still required before assembly. The aileron mechanism has been repaired to ensure the ailerons can move along their correct path.
The elevators also need to be repaired, as for example one of the elevators was not straight. Furthermore, the counterweight of the other elevator was replaced with the correct type of weight.
These are the main points for now. This article is the response to many inquiries about what is happening behind the scenes in the Myrsky project. The aircraft will be completed in 2026, but the exact date is not yet known. Photos: Jorma Laakkonen Translation to English: Erja Reinikainen |

MY-5 fuselage frame brought from Finnish Aviation Museum to the Puusepäntie workshopPerjantai 21.11.2025 - Tuesday Club member The Tuesday Club has been working all autumn at the Finnish Aviation Museum and also at the Aviation Museum Society’s workshop in Puusepäntie to build the Demo-Myrsky. The Demo-Myrsky is built to display the inner structures of the Myrsky II fighter, designed and built by the Finnish State Aircraft Factory. Myrsky had a mixed structure, its fuselage was made of welded steel tube and the front fuselage had aluminium plate covering and the rear part was covered with fabric. The wing, the vertical and horizontal stabilizers and the rudder were made of wood and covered with plywood.

Before the Myrsky fuselage was brought in, some rearranging was needed in the Puusepäntie workshop so that the MY-5 fuselage would fit in with the Super Chug OH-XTM and the Snoopy OH-XEA fuselages, which are already there. When the preparations had been made, the MY-5 fuselage frame was loaded on a trailer, waiting outside the museum, on 17 November. On the following day the trailer was fastened on the towing hook of the Octavia and the journey to Puusepäntie began.
We can soon call the workshop the Aircraft Factory of the Aviation Museum Society! Photos: Lassi karivalo, unless otherwise mentioned Translation to English: Erja Reinikainen |

The MY-14 wing has been paintedTorstai 3.7.2025 - Antti Lappalainen & Reino Myllymäki The MY-14 wing was transported from Vantaa and the Tuesday Club’s Myrsky group hands to Tikkakoski and Finnish Air Force Museum's restoration group for necessary modifications, painting and joining to the fuselage in September 2024.
The modifications on the wing took the winter period 2024-2025 and the spring 2025. When I visited the Air Force Museum on 12.6.2025 the transportation and painting trestle was being assembled to the wing and after a couple of days on 17.6.2034 the wing was transported to the premises of Haklog Ky for painting. The painting was mainly done using a high-pressure spray gun. It yields thicker layers of paint, although the quality of the surface is - depending on the type of paint - worse than with a side air brush, which was used to paint the swastika, mid-wing and black areas. The incentive to use the high-pressure spray gun was the fairly large area of the wing where the alkyd paint in use was known to give a smooth surface.
Because of the modifications the wing, which had been primed at Vantaa, had to be puttied and sanded, so the wing was given a once over with the Future-3-primer to the shade of RAL 7005.
After the primer the wing undersides were painted light blue with Teknosynt Combi 50 paint, with a shade that was called DN-blue during the war, and is now called RAL Design 220 60 10.
After the underside, next in line was the upper side green part, painted twice. Between the layers of paint, the surface was sanded. The paint was still the Teknosynt Combi in the shade of Teknos TM-11263/20.
Following the upper wing green area, the black camouflage of the plywood surfaces was painted. According to the instructions of the State Aircraft Factory, only one layer was painted. The borders were painted with low pressure spray gun, in order to make the borders sharp. After that the central parts were painted over.
Next in turn was the painting of the Eastern Front decals to the wingtips for a length of about I/6 or 183 cm. The painting was done with fully glossy Futura 90 using the Teknos TM 11297/20 shade.
For the painting of the national emblem, a circle 1 metre in diameter, was cut from a thick cardboard and a template for the swastika. The emblems were positioned with the help of the templates and using a laser and marked with a pencil. The circles were taped, and the rest of the wing was covered with plastic. There wasn’t enough of anti-glare paint for the emblems, so more had to be mixed using the corresponding paint for the fuselage as reference. The circles were painted with high pressure air gun.
The swastika in the circles was painted with the same method using fully glossy Teknosynt 90-paint. The shade was Teknos TM 11264/20. The last parts to be painted were the parts in the mid-wing, that are covered by the cockpit and the wing root fairings, with Temalac FD 80-paint in the shade of RAL 7005. Notice and guide markings and the markings for the service hatches are yet to be painted. Modifications for the aileron push rods are still unfinished and there are still holes in their coverings. But because the national emblems are hard to get identical, if their parts are painted separately, the part of the national emblems was painted now on the ailerons. For their part the yellow and black areas will be painted together with the wing root fairings, elevators and the rest of the missing pieces of covering.
After the painting, the wing was transported by the Defence Forces from the premises of Haklog Ky to the Finnish Air Force Museum on Wednesday 2.7.2025. The wing, with its transportation and painting trestle, was placed in the main display, next to the fuselage of MY-14. There the aircraft will be admired by the visitors and wait for the end of the summer holiday and the beginning of the autumn operations.

The Myrsky Wing transported to be paintedTorstai 19.6.2025 - Reino Myllymäki The MY-14 wing was transported from Vantaa to Tikkakoski in September 2024. Since then it has undergone modifications with the restoration group at the Finnish Air Force Museum till the spring of 2025. In the wing standard hardware store bolts and new production parts have been replaced with original parts. Original parts of the wing have been conserved, and some parts of the wing have been modified according to the blueprints, for instance by removing and adding service hatches.
As I visited Tikkakoski on Thursday 12.6. these modifications were nearly finished and a trestle, made according to the blueprints by the State Aircraft Factory of wooden 2x4 inch beams and bolts, was fastened to the wing. The trestle was attached to the same brackets as the fuselage. The trestle positioned the wing at a steep diving angle, with the leading edge pointing down. This allows the 11 metres long wing lower and upper surfaces to be painted without nearly any obstructions.
On Tuesday 17.6. the trestle and the wing were taken out and hoisted on a low-bed trailer to be transported for painting to the premises of Haklog Ky.
At the Haklog Ky the wing was brought into the same workshop where the MY-14 fuselage had been painted in the autumn 2024. There was a shortage of the wing lower surface blue paint, but luckily Jorma Laakkonen happened to bring a 9 kg tin of paint from Vantaa. So the Air Force Museum had all the necessary paints at its disposal.
Without any delay, the upper and lower surfaces of the wing were primed grey.

And then the completing of MY-14 will be close. Photos: The Finnish Air Force Museum, unless otherwise mentioned Translation to English: Matti Liuskallio |

Finishing the MY-14 flapsMaanantai 12.5.2025 - Reino Myllymäki The original flaps of the VL-Myrsky fighter were found in the spring of 2014 in the stores of the Finnish Air Force Museum (until the end of 2015, the Aviation Museum of Central Finland). Until then Aviation Museum Society’s Tuesday Club’s Myrsky team had only one flap at its disposal and the building of the other one was being prepared.
Photo: Reino Myllymäki The Myrsky flaps are panel flaps, mainly made of duralumin, which can be opened to any position between the extreme positions. They are operated by the same electric motor as the landing gear. The original green colour of the upper surface of the Myrsky flaps has remained and it was decided to preserve it. The lower surface, instead, will be painted along with the wing to the same paint scheme as the rest of the aircraft. The flaps were returned to Tikkakoski in the same load with the wings in September 2024. When preparing to join the fuselage and the wing, various preliminary finishing touches have been done to the wing. This has included conservation of original parts, replacing parts bought from shops or refabricated with original parts, and preparing the wing to accordance with the blueprints.
The steel hinges of the duralumin flaps were rusty. They were sandblasted at Tikkakoski.
The drive shaft of the flaps is joined at both ends to bearings. For some reason the drive shaft was lacking the part linking the shaft to the bearing bracket. It had to be refabricated by lathing according to the blueprints. The MY-14 is again a step nearer to completion. Photos: Finnish Air Force Museum, unless otherwise mentioned.

An update from TikkakoskiMaanantai 28.4.2025 - Reino Myllymäki The restoration group from the Finnish Air Force Museum informed us today about the progress on the work with VL Myrsky MY-14. The wing was built at Aviation Museum Society’s Tuesday Club and was transported to Tikkakoski on 18-19 September 2025 for finishing and compatibility purposes. This process has recently been going on to advance the project. The aim of this work is to eliminate the discrepancies between the wing and the blueprints, to secure the use of original parts, when available, instead of new parts, and also to ensure the conservation of original parts.
The brackets for aileron movement have been relocated according to the blueprints and some bearing brackets of the aileron mechanism have been replaced with original parts.
Some bearing brackets of the flaps and flap mechanisms have also been replaced with original parts. A component for the flap mechanism was missing, it has now been lathed and installed into place. Additionally, some operating rods have been changed to match the blueprints.
One service hatch has been made in the right wing, a limiting switch has been fitted, and missing ribs have been added.
The rib battens have been changed to match the blueprints at the wing root and around the wing tip lights and pitot tube.
A transportation rack for the wing has been made. As is well known the Myrsky aircraft had four different wings, namely the wings A, B, BI and C. At the time of constructing the MY-14, it was decided that its wings were built like the B and C wings where applicable, in the belief that that a complete set of blueprints wouldn’t be found for any of the wing types. As the restoration project went on, the situation has changed. More blueprints have been found and at this moment there are practically complete sets of blueprints for all wing types. So now it’ll be possible to change the wing of the MY-14 externally similar to what it was actually like at the end of the Continuation War (a strengthened A-wing/early B-wing.) The external measurements of the wigs are identical, the differences are mainly inside the wing. Photos: Finnish Air Force Museum. Translation to English by Matti Liuskallio. |
