I'm sure that everyone will tell you it's OK...
However I find that:
- Balsa absorbs water and can develope mildew and rot if it gets damp.
- Little "critters" just love to eat balsa...
Especially mice, I have had to remove the covering on wings just to dump out several cups of dog food that mice decided to store inside.
I have one of those cheap sheds and part of the build instructions required a plywood floor, at least the one I bought.
