Arnold E, there is nothing "Fragile" about LSA or RAA aircraft under loaded conditions when airborn.
I too have seen three wrecked RAA type aircraft (sportstars) and in each case they were mishandled either on the ground or landing.
These aircraft have much less tolerance to mishandling on the ground in my opinion. That is the source of trouble. They have short little gear legs that require you to land flattish and they are light and respond quickly to gusts and crosswinds, so you need to be on your toes. The Sportstar also runs out of aileron a little too quickly at low speed as well, hence gravel rash on the wingtips and ailerons.
