Hi David.
Its hard to tell from the photos but it looks like youve made a nice job of this old Airfix kit.They can certainly be problematic in their assembly.
I guess from the strategically positioned jar of paint that you have a tail sitter.
To help you remember,,"P-38?,,,add some weight!"
Some small fishing weights or similar will avoid the Lightning sitting down.
Well done,,,whats next?
