I feel for your loss, but I can't say that it's all their fault nor is it yours. I have to interpret the claim as a 50/50 problem. They as a distributor try to provide you with a quality product and you as a buyer want and expect a well built kit. Here's the problem, they can't open and inspect every plane that comes from china. So now it is really up to you to decide what is acceptable and what is not in the basic construction of an aircraft. In some cases the problem areas are obvious and in some cases they don't appear until flight conditions occur. Now were down to the 50/50 responsibility of any manufactures product, they expect you as the customer to make the judgment call as to what is acceptable and what isn't. Not to mention that you should have noticed that when drilling the servo holes, it was only 1 layer of wood to screw to and no doubler. I see where your coming from and that there should have been a doubler but since it was forgotten you should have rectified the problem and notified the manufacturer of the mistake so you could cover your investment in case something goes wrong. It would be hard to fight someone who questions a manufacture on it's product and then have it fail after the report of what was in question. I've owned a few GSP arf's and I think the early ones needed a lot of help but were usable, their current arf's like the Zero I'm working on are very good and need almost no modifications to make them flight worthy.But to assume that it's o.k. is foolish and dangerous, The old saying is never assume because it makes an "ASS out of U and ME" This is how most manufactures feel when dealing with a customer complaint due to their product failing. What the manufacturer should have done is asked to pick up the product and inspect it to verify the product in question and make an educated opinion on the claim, if it is a legitimate problem, then they would take care of the issue. But if they find no problems with the kit, then they would offer to replace the plane at a reduced cost. That is in a perfect world but in reality, there are shady people in the business and it's up to you to safeguard yourself from their poor business practices. So "buyer beware!"[:-]
