In 1966 I built the 500 series FW 190. I knew nothing about Balsa wood models that fly. I was 15 years old. The first thing I noticed was I could not use plastic testers model glue for wood models. Some how I got the frame built, and covered. Took it out in a field, wound it up, launched it. The plane stood on its tail, stalled, crashed. I dont remember when I noticed the ballance her marks on the plans, most likely a few planes after that one. Since then, I've built many free flights, radio controls, and now park fliers. The 60's was the most fun with all the gas free flights....
Keep the fun in it......
