My two favorite flyers are a pair of Baby Flite Streaks, one with a Tee Dee .051 and the other with a Big Big .061. I fly them both on 45' lines, the Tee Dee with a 5.25x3 prop and the Big Mig with a 5.5" or 5.75x3 prop. I've been building kits since I was a kid, but with no experts to help me. And when I flew my first Baby Streak, I felt like I was flying my first plane that wasn't a toy.
