I have often wondered how many people we have out there in this great land of ours that fly control line maybe once or twice a year and don't know what AMA is. When I got started in this hobby/sport I didn't know about AMA until I entered my first contest in 1956 with a Guillows Rat Racer and Mccoy 35. Even reading about the Nationals there was little mentioned about AMA that I can remember. I just flew my Sweet Sweep in Topeka a couple of weeks ago without numbers on the wing or even the fuselage. I have also read where some of our better known pilots have test flown planes without any numbers/finish on them. So how does that little plane fly? DOC Holliday
