Super Alpha Build Part 4 Fins

It's hard to see in the picture, but the balsa sheet from the kit was made from two pieces of balsa, glued together parallel down the grain line.

The Super Alpha instructions have you round only the leading edges of the fins.


The original Alpha instructions say to round the leading edge and taper the trailing edges. The illustration showed a rounded leading edge and a short taper at the rear.
Enlarge the illustration at the left and look at the "A - A" section.
I decided to round all the edges, except for the root edge.
