Wow I was all ready to list my weight of my Kadet SR Arf then I realized we were talking about 3 different planes hear. Built Kadet SR, Kadet SR(arf), and a Kadet.
Anyway my Arf Sr Kadet is 5 years old with no problems weights 8lb even with a 72 4cycle Satio, and is converted to a tail dragger with a external servo in tail for steering.
