Home Depot and Lowes both carry Aspen and Poplar. Lowes has the best Aspen and Home Depot for the Poplar, at least of my two stores. And fortunately they are across the street from one another. I will usually spend about an hour at each going through the entire stacks and pick the best grain of the bunch.
I believe the use of these woods over the normal hardwoods is why my Waco survived a cartwheel with only one balsa wing tip break.
