Magpie Specifications
Length: 34in.
Wingspan (SF): 46in.
Wingspan (SP): 40in.

Thank you for purchasing the Magpie. The SF or Slow Fly model is an elevator/rudder setup,
designed for the beginner pilot who wants a robust trainer. The SP or Sport model also has
ailerons for the pilot who wants to step up to the next level of flying. The wings are
interchangeable. Built properly, the Magpie should survive the majority of crashes you are likely
to experience learning to fly.
