If you need 2 mm coroplast go to Harbor Sales. They will ship ups after they cut a 4X8 sheet to your specs. I just ordered a sheet cut into 2X4 pieces total cost shipped to me just $15.92. They take your order over the phone and are familiar with the needs of our hobby, very nice people too. That will open up your choices of planes to build with 2mm wings.
