I cleaned the balsa and ground down the rough edges on the glass...so I'm ready to start rebuilding.
A couple notes worth mentioning after looking at the broken rudder:
1) The rudder has a foam core (i think) that is shaped, then has balsa wood wrapped around this "shape". The balsa wood is uniformally 2 sizes:
a) 1/4 inch balsa between 3.25 and 5.25 inches from the trailing edge (it's not shaped and is uniformally the same thickness).
b) 1/2 inch balsa 5.25 inches from the trailing edge to the leading edge (it as well is not shaped and is uniformally the same thickness).
2) The balsa wood was so rotten that using the claw on a hammer I could just pull the balsa off...no chissel was required this time.
