am about to build my first flying wing plane.
I wanted to know which foam would be best for this type of plane.
I want to build airfoil with hot wire cutter.  So, please tell me foamtype that I can find in a foam store.  

Hi Dixant

Use depron.
If you don't find that, go with coroplast.
If its your first plane, then you should go with coro. It can handle quite a beatings from a beginner 

Wire cutting then High density Thermacole seal packed in thick film after cut.

just use coroplast(corrugated plastic sheets) for your first plane.
use this site: www.spadthebone.com --> see free plans
this might be help you....

you could use blue foam or hd thermocol

can thermocol be used for making planes ??
