The Hangar 9 Twist 3D in .55-class size — sized between the .40 and .60 variants of the Twist 3D family.

The .55-class engine sizing falls between the smaller .40-class and the larger .60-class Twist variants. A natural sibling of the Twist 3D 40 (CV Planes Pack 6) and Twist 3D 60 (Superfast Planes pack).
A serious 3D mount with the typical Hangar 9 Twist family handling.
