I added two wooden stub spars going thru the fuselage for proper structural support. It is a must for any build to have sound structure or else the model will warp and as it sinks over time, it would look silly.
wings are glued on
Notice the anhedral of the wings. The wings have a downward angle. That is common to all Mig-15 and 17. Often you see modelers ignore this feature ( or are ignorant to it ) and build their Migs with straight out or even dihedral wings.
both wings are glued on.
Wing fillets
Here are both wing forward fillets.
However, there is an error here. Both fillets are identical and suitable to the right wing only.
I used the spare color sheet to make a new left wing fillet.
my opinion:
There are numerous small errors in this kit. I think the right thing to do by those capable, is to scan it all and repaint or correct the errors prior to printing it. Building the model from the purchased print and then substituting repainted parts will be a difficult task..
