Dick Sarpolus has been a model airplane enthusiast since he was eight years old. He's built and flown every type of model aircraft and has been active with radio control and control line models for more than 30 years. He's won more than 100 trophies and has directed a dozen AMA-sanctioned model airplane contests. Dick also enjoys designing model aircraft; more than 50 of his designs have appeared in model aviation magazines in the United States and Europe and a number have been manufactured as kits. Dick says that he wrote this book "to introduce others to the fun and excitement of control line flying."
