Ron, poplar is a nice wood choice. It has several qualities that make it a good choice. it is dimensionally stable, easily worked and takes glue or fasteners very well. Poplar takes paint quite well if it has been properly dried, but is also nice if stained. Poplar is quite economical and is available in all kinds of thicknesses, widths and lengths. All woods can twist, but poplar is less prone than many others. I have found it to be great for a lot of my prototype work because of these properties. Good luck,
