EPP foam is the most impact resistant foam used by modelers today. It was originally used for Slope Combat airplanes that could survive mid air collisions and crashes with little or no damage. It is commonly used for small electric airplanes that are flown indoors and many types of airplanes, gliders and UAV's that will be subject to abuse.
EPP foam cores are typically covered with low temperature covering films such as Ultracote® and/or Color Tape. This method works well for small electric powered models and gliders. EPP foam cores are not compatible with vacuum bagging methods. Most EPP foam wings will require reinforcing with wood or carbon spars and/or wing tubes.
EPP Quick Order Cores are available as Constant Chord or Tapered cores with any of the 26 airfoils shown on this page.
