I can try to tell little bit about this fighter. Sorry that my English is not good enought.
Finnish "Tied.Lev.Lv 12" (Reconnaissance Squadron number 12) was first squadron which got these fighters on August 1944 at Mensuvaara airport. Photo above was actually taken at Mensuvaara war airport. Mensuvaara was one of most important operation airfield on Finnish-Soviet eastern front. The airfield situated near the big lake of Ladoga.
Myrsky II fighter coded MY-5 (picture above) was one of first arrived fighters. First weeks pilots were trained to these new fighters. They also trained in the air by dogfighting with other Finnish airforce ("second line") fighters like Curtiss Hawk 75 and with a captured Soviet LaGG-3 fighter. These dogfights showed that Myrsky was faster in speed and climbed also faster than an old Hawk 75A. On the other hand Hawk 75A could make tighter turns than a Myrsky. What comes to Soviet LaGG-3 fighter, Myrsky was little bit faster and much rapid in turns than LaGG-3.
12 000 hours is huge work to do. Long time ago here was very similiar project. A Fokker D XXI fighter was built by a small team. It took ten years to built it and now you can find it at The Aviation Museum of Central Finland.
I guess that for Myrsky project we have much more voluntary work available. So I believe that the fighter can be ready on 2018. It is estimated that whole material (+ devicec and work??) for this project will costs 76 000 euro (104 000 US dollars). I guess that it is not much.
According to a web page, For example making brand new NACA cowling will cost 1500 euro, main landing gear 10 000 euro, Digitalisation of original paper drawings 15 000 euro etc………

It was also thought to built two VL Myrsky II fighter at the same time. You know, if you produced new parts for one plane, it is not a big job make extra parts as well. It was found that there are no space for two Myrsky II fighter in Finland.
