Seems to me the weight limit might be a contributing cause of the crash. The bigger models built to attend the event may sacrifice proper construction in order to meet the weight limits. Of course even a properly designed and constructed aircraft an be overstressed by pilot error. Remember the Airbus that flew into wake turbulence and lost its vertical stabilizer when the pilot danced on the rudder and overstressed the structure.
