I assembled an Airbus A380-800 model. I had no prior experience in assembling models however I used to play Lego as a kid. This model took about 2 weeks to complete and I did it during my sabbatical. It was a bit harder than I thought it would be and I did unrecoverable mistakes when gluing and using the stickers but overall it was a great feeling to have it done. Now it has its dedicated space in the living room.
