Hi Stephen,
For the spars, what size material do you need?
Balsa sheets are a standard 1000x100mm
9mm: Not available (8 or 10 for the nearest)
3mm: 1.11euros/sheet
I am waiting for the Quote for everybody. Mail / thread will be updated for cost etc for everybody. I try to get a discount seeing the volume of wood we are buying, I'll let you know.
