This product is a replacement tail set designed for the Apprentice STS 1.5m RC airplane, including both the horizontal and vertical stabilizers for restoring flight control and stability. It is molded from durable EPO foam for improved strength and resistance to wear compared to earlier designs. The set includes matching graphics for STS models and installs as a direct replacement for damaged or worn tail components. It is also compatible with Apprentice S 15e models, though without matching decals.
