This is a set of accurate parts to replace the impulse engine and crystal parts for the Round 2 1/350 Refit Entperprise. This set comes with three parts:

• The impusle engine itself, recreated more accuratley based on the studio model. The floor of the part hangs down at the correct angle. The details on the divider between the two vents are inscribed now, instead of set in relief. The vents themselves are included and have the accurate number and shape of slots. • The impulse crystal housing is not a solid part, but just the ribbing and supports for easy painting with no masks. • The impulse crystal itself which can be easily inserted into the housing after painting. Comes in frosted clear so just lightly sand and gloss for a great, refracting appearance.
