I am in the need for a blue core foam which is around a 1inch (25mm) in thickness. The exact type of foam that I am looking for is the blue Styrofoam EPS, EPP.
Did some search here on rcindia.org. Depron is the most common build material, while I am yet to come across a thread where blue Styrofoam EPS, EPP is used.
I am looking to hot wire a pair of airfoils out of this foam block. Let me know where can I get this material.
Also, if anyone has used material other than EPP/Styrofoam EPS to make an airfoil please give some pointers.
Thanks.
