PS.. i notice that you said 660cm LONG if you really mean 'length' (from nose to tail) then that would only give a wing span of around 50 -55cm. For a plane that small you would be looking at a micro 50mm EDF unit.
Be warned...Smaller model can be harder to fly than larger ones, especially fast small models!
If i were building it I'd do it out of balsa, but that's because i've been using balsa for the last 40 years and i like working with it. With the correct use of materials I'm sure it would be possible to design and build a very nice model out of balsa or foam, it depands on your preference.
