Thanks guys.
First two engines attached. Just hope they don't move, epoxy!
I'll fix the other wing up then fill the gaps on these while they set.......
Filling gaps with body putty, filing and sanding, priming and sanding and filling again. Back and forth. now doing the leading edge of the pylons at the wings. A couple of fillings, filings, sandings and priming and I should be DONE!
