I think it flys great - *much* better than those 1/3 or 1/2 scale models that weigh 70-80 lbs and fly like kites!
+1, .. nothing against giant "kites" but this is nicer in my opinion.. and about safety concerns I am sure that how much this model weights is irrelevant as this kind of models are always flown in a proper and safe place.
Fantastic model.. very nice to watch it fly.
