I'm helping my son build his first rocket for cub scouts which is an Estes alpha.
This is a curiosity really, but the pre-cut balsa fins have maybe 1mm clean drilled holes near the root in the upper third of the fin.
Do they serve some purpose?
PS I'm actually returning to the hobby after 40 years. "In my day" you actually used a knife to cut out the fins ..I certainly never drilled holes in them.
