Last summer I had a 16 year old Goldberg Eagle with a OS40. If I hadn't striped the covering, my plane would most likely would of crashed later this year. It had Balsa Rot due to the prevous owner didn't store it in a heated environment. Plus Glow Fuel worked its way in through the patches through the years. So I took the whole plane apart, and I'm going to use what ever is good for repairs on other planes. May you Rest in Peace my friend.
