IT SEEMS THAT YOU SHOULD BE FAMILIAR WITH BUILDING BIGGER THAN ABSOLUTELY NECESSARY. THE LT-40 IS MEANT TO TAKE A LOT OF ABUSE (IT'S A TRAINER), SO LOTS OF THINGS ARE "OVER_ENGINEERED".

On the other hand, the plane has been designed to be able to carry the extra weight. The extra weight is worth the benefits o being able to beat the plane around a bit (hard landings, etc).

SO, SINCE YOU SEEM TO UNDERSTAND FULL_CAPS LOCK, YOU SHOUDL BE ALSO ABLE TO APPRECIATE THAT AT TIMES, "BIGGER IS BETTER".
