I built a high-wing trainer in 1980, flew it three times and hanged it up in my shop. After 30 years I have decided to use it to teach my wife to fly RC. I cannot remember what kit this aircraft was built from. It is either a Sig Kadet or a Goldberg Falcon. I am leaning toward the Sig Kadet. It has a 63" wingspan, no ailerons, heavy wire tricycle landing gear, and the horizontal stab is built-up flat construction with no airfoil. This particular airplane had formed plastic wing tips which have deteriorated over the years. I was hoping to replace the tips if I they are available, but I will need to identify the aircraft before I can hope to find the tips. If I cannot locate tips I will build them with sheet balsa. Any input would be appreciated.
