Hi Bruce, flaps on a Flite Streak will cause the model to turn wider than sans flaps. Yes, the Streak
will turn much tighter without flaps. I suggest you move the CG back in small increments until
your model gets twitchy; then move the CG fwd about 1/8". Flaps help a model turn smoother
because of the opposing pitching forces produced by the flap versus the elevator. Good luck,
Tony
