The Flite Test Power Pack B "Radial Edition" contains everything needed to power the Small Fixed Winged Planes such as the Flyer, Delta, Nutball, FT22, Old Fogey, Old Speedster and most other airframes that weigh between 1-2 lbs. The only other components you will need to fly is a battery, charger, transmitter, and receiver. The included Radial motor and ESC comes pre-soldered with 3.5mm Bullets and XT60 Connector. Tech Note: Depending on your propeller choice, some propellers may require a prop reamer to enlarge the hub size to fit over the motor shaft. Prop reamers can be found here, and offer a variety of "sizes" to ensure you have the proper hole size for your motor shaft.
