This ballast set is designed for the Sprite Hot and Thermal, but also works well for any model needing a physically flexible ballast system. Adding ballast improves performance when the wind and/or lift is strong. Ballast allows the model to be flown fast without loosing as much height as it if it was just dived.
The Sprite ballast is assembled on a flexible wire cable, which makes it possible to fit the ballast in more constrained places. This makes it especially suitable for F5J models.

6 pcs 27 g aluminium ballast slugs with a diameter of 16mm and the length of 50mm
6 pcs 80 g brass ballast slugs with a diameter of 16mm and the length of 52mm
2 pcs noncorrosive wire for fastening of the slugs
Screws for fixing of ballast in the fuselage (also one spare screw)
Allen key for the screws
