The VAPOR weighs 17 grams ready to fly (60% of one ounce).
That's heavy; mine weighed about 12 grams including the battery, well below 1/2 oz. What a superb little plane....ez hovering, consecutive loops, inside or out, inverted flying, and even managed a roll or two with it. Alas, my grandson, for whom it was intended, stepped on it more than a year ago. No more Vapor
