After a week of cutting, gluing and sanding I completed the construction phase of the Guillow's Bird-Dog. This 18" wing span monoplane is a relatively easy build. I added some of my own small modifications, such as some wing strengtheners and gussets as well as hand carved balsa nose as the vacuum formed plastic version was rather flimsy. Instead of using card for the fillets around the cabin I used 1/32" balsa sheet. The next task is to cover it with tissue..
