I called Sig today to order wood, and the lady who answered the phone said they were out of balsa and were no longer carrying spruce. I remember trying to order a 4*120 kit last year and was told kit production was on hold due to them getting a shipment of bad balsa. I'm putting the 4*120 together now and I'm not impressed with the wood that came in the kit. I understand that China's buying a lot of it up and it's going into windmills and that nobody's balsa is what it was 5 years ago, but I had to replace several balsa pieces in the kit...some of it was softer than butter! I've built and flown several of their planes over the years...hope they get things worked out. Anyone else have any info?
