Sheila,
i was going to 'warn' you that the P-38 can be a bit tricky w/ the muliple wing and boom sections. alignment, angles, dihedral & what-all.
then i remembered that your kits already look better than mine!
but be sure too do a mock-up w/ masking tape & test fit all the major sections w/ one another.
and make sure you post it over on the aircraft side !!
