Thanks guys.

I'm pretty much there now. I didn't realise that I would have to modify the wing so much and thought that I must be doing something wrong. I have had to hoover the inside of the wing as there was so much dust in there!!

I need to reinforce the gear mount plates again as I ended up taking a bit too much material off to get them to fit. I have also had to mount one unit crooked to get the clearance. This has caused quite a bit of toe-out but re-filing the pins will sort that.

I assume that you have not used the 'inserts' that go into the wing under the retracts. Has that caused any problems?
