RE: Someone mentioned warped wing
Remember eating white paste as a kid? It smelled good... wonder why it didn't taste good. Inquiring minds want to know!
Here's 108" span of glory assembled with wood glue. No warps, runs or cattywhompers! The third pic is an S-1 Ringmaster which is as straight as the theoretical line on a Cartesian Plane from point 'A' to point'B'. The fourth is another Ringmaster wing seen on edge. It's straight and I used yellow wood glue.
