I see. That I didn't know. When I look through the armor thread this is all it says about FX:
Type: FX
Country: USA
Availability: FX is not currently being sold. Do not buy from e-bay - kits are over-priced, the quality is often dubious, and always recast.
Contact: N/A
Kit: ABS, trimmed, fan sculpt.
Comments: It's good, robust armour that will hold up to a lot of abuse. While the helmet is fading away, the armor continues to be popular and will be in the Legion for some time.
