  • Page 4: Introduction

    INTRODUCTION Your new 50cc Pitts Python ARF-QB is a highly aerobatic airplane. It is capable of both pre- cision and 3-D maneuvers. The aircraft builds easily, quickly, and precisely due to its state of the art CAD design, LASER cut technology, and high quality included hardware. We hope you enjoy building and flying your 50cc Pitts Python ARF-QB.
