All I know is the SPAD materials- durable and heavy. I am playing around with the idea of making my next wing out of foam, but am curious if it saves weight and also how it compares to coroplast for strength.
Not quite accurate. My Cor-Star series of coroplast planes come out within a pound of their balsa sisters. Of course, the durability is a no brainer. 500+ flights on the airframe in the picture. Foam cannot cut it when it comes to durability with coroplast.
