First of all, the foam ratio has been upgraded from EPO 40 to the lighter and larger EPO 52, which alleviates the airplane's weight, without weakening the airplane. Moreover, the original oil paint which has an unavoidable negative side effect of corrosion has been replaced by the latest environmental water-based paint.
