Sporty's has its own luggage scale that will save you from guesstimating the weight of your bags or using standard baggage weights. The lightweight luggage scale is simple to use and can be carried with you in your airplane. Just attach the hook to the airplane and hang your luggage bag from the hook to get the exact weight of the contents. The scale can accurately measure up to 55 pounds. You can order the luggage scale, item #6910A, for $19.95 from www.sportys.com or call direct 800/LIFT-OFF or 513/735-9000.
