It flies
980mm wingspan. In fact this assembly was not made for flight, but just for see 3d model shape =)
There are number of problems in assembled airplane like printing issues and big elevator backlash about 10-15 degree
Aerodynamic was calculated correctly and confirmed in worst conditions: overweight about 50% (takeoff weight 1.5kg instead of 1kg) - 107g/dm^2
This is very heavy because soviet warbirds has small wings and it's very hard to make them fly well in model scale. This need proper aerodynamic analysis and it's was done before 3D modelling.
At the end I lost control because I have flew wihout gloves this time and after a minute I could no feel my finger anymore. Russian winter...
Airplane is OK, only one crack on fuselage (delamination of layers on printing issue sector)
To be continued...

Seriously impressive! Well done.
I had to laugh at that! I am sitting here in summer the Australian outback with my air conditioner going!

My children said to say the same as you, but in reverse, they think you are so lucky because you could make a snowman with all that snow!
