Manufacturers should pay for this kind a thing when it is manufacturer related and can be proven. They make a product and do not do adequate testing and use the public to do there testing at the customers expense . When and aircraft is released for production rigorous testing should be done to eleminate all problems then sell it to the public. I beleive sometimes some of these people who design do not fly and do not understand the power of some of our models. I had a problem with a mufacturer from Germany one . They release a kit and mix the clevises metric and standard threads . The aircraft crashed but the company replaced it with a brand new model .

Only my view on this incident.
