I can recall building Guillow's kits from many years back and am now questioning the quality of the balsa in modern day balsa.
When I chose to use Cox .020 or .049 power I frequently hand-selected the stringers at the LHS and I'll possibly follow that option today.
Having not built from balsa in many years, I have no idea of the quality of kit OR LHS balsa. What's the "wisdom" on this matter today?
