You guys must be pretty rough on these little planes!! I have about 4 gallons of fuel (20 min per 8oz) thru mine & I thought I've been pretty hard on it - endless flat spins - harrier landings - tailwheel touch & goes etc. etc. etc & no sign of anything cracking or breaking. Even smacked the ground from about 6 feet up and only bent the gear a little.
There are 5 of these flying at my field & all get pretty much the same abuse

& none have shown any weekness anywhere. Ya never know though mine might fall apart tomorrow!!!
