what kind of balsa do I use to wrap the wings in 3/32" x something x something? I went to my local hobby shop and found the same kind of balsa but it was way too thin - 1/32". I'm just wanting to know what kind of balsa it is so that I can order more from Towers. Also, I noticed the balsa on the body of the plane is harder/denser - its not plywood. that kind of balsa the hobby shop has plenty of.
