YESSSS, Package Tape does wonders on Super Cub Repairs, my rear fuselage also broke after being treed for several days, tape is amazingly strong, the Cub is so forgiving on my first repairs even used Heavy Ductape, not a good idea, and yes it also held up well, my wing broke in half, tape fix was durable, still flys like a champ...Good Luck...
