No offense to your prof but unless he's an aeromodeller he may not fully understand the stregth to weight requirements of a model as well as our own folks do. The stuff you will find that is written...

Only if you don't try a hard launch. I suppose you COULD make up a mulitlayer wing section that would be stiff and strong enough but the wing would come out mucho heavy. Too heavy to fly well. ...
