Looks a bit like a balsa model from what I can see in the pic. It is a little difficult. You could of course try several other foam products. Some guys are having success with blue foam and such. Do some research here and on the sites. You should find something that will work. Like us guys here in SA are forced a bit to use an extruded foam. It is used to make iso boards. This stuff in particular is quite light but very fragile as well. Does work for a foamy I suppose but it will not take the beating depron will.
