Expanded Polypropylene Foam-EPP FOAM
Hello, i am about to buy a high-wing sports trainer made of EPP Foam. The model is the "Prangster" by JP. It is advertised as being almost indestructible and very durable because of the particular material used in its construction. However, i have the following questions:
1)How tough and indestructible is this material?
2)Is it repairable?
3)Will the aircraft perform and feel like flying something "spongy"?
Any advice and past experience is welcome.Thank you.

RE: Expanded Polypropylene Foam-EPP FOAM
EPP foam is often used for packing materials and the 'core' of automobile bumpers. Tough stuff...
1. You can stomp on it and it will simply bounce back.
2. EPP can be glued together with polyurethane glue or Goop.
3. This is totally dependant upon the airplane. If there is a stiff enough spar and the wing is covered with Ultracote (Monokote doesn't work as well here) the resulting wing is pretty stiff. It wouldn't make a good pattern plane but it is GREAT for combat planes.
