thanks for the comments and for looking in on my project
I've got he fuselage halves finished and joined together, the fit is pretty good and only a slight fettling was needed.
I've put part of the carriage together and PVA'd it to a couple of stirring sticks, this should give me a steadier platform when fitting wings etc.
The upper wing is now assembled and I added a couple of .8mm brass pins to give it a bit of strength.
The underside of both wings are now painted, they look white but do have a slight shade to them, i mixed up mainly white but added some brown and grey to create a slight off white colour, gotta be honest it looked a bit darker in the mixing pot than it does on the wing but when seen next to white you can tell the difference.
Before painting i used a pencil to add some dark grey to the spar grooves on the underside, after a few coats over the top of the pencil lines i think it looks ok
