This set includes the same fully transformable YF-19 previously released in 2006, but this time complete with a fold booster and fast pack attachments for extra boosting power! Made of ABS, PVC, and die-cast materials, the YF-19 can transform between Fighter, Gerwalk, and Battroid modes, and stands 34 cm tall (a little over 13 inches) in Battroid mode. A Gunpod, a pilot and passenger figure, and decal sheet are also included. Yamato also provided two types of holders that can be attached to Yamato's Valkyrie display stand (sold separately) to show off your YF-19 in any of its three modes. The fold booster is nicely detailed and features light-up LEDs (three button batteries are required, not included, for the LEDs to function). A display base is provided for displaying the fold booster as a separate piece if you like. If you don't already own Yamato's YF-19 and the Fold Booster & Fast Pack Parts set, this is a highly recommended addition to your collection!
