Assembly Instructions
Important notification
1.The model is supplied with UFO and 502 glue. UFO is for bonding foam parts, and 502 for
bonding wood, carbon fiber and metal parts. 502 glue will cause serious corrosion to foam parts.
2.Please wait for the glue to dry and solidify in each installation s tep before the next installation.
3.Please avoid using flame to heat the heat shrinkable tube on the model. Electric iron shall be
used for heating.
