I have been flying for many years, and now turbine jets for 10 years. In that time I have flown many manufactures airplanes, and I have seen many failures from ALL manufactures.
Some of the ones I remember specifically from RCU over the years:

Multiple Hotspots where the fuse blew apart
Multiple Eurosports where the rear hatches blew off and the fuse came apart
A BVM Super Bandit where the wing spar failed
BVM Kingcat boom failures (1st generation, lead to carbon plates glued on the outside)
Skymaster wing delaminations
A Yellow Aircraft F18 twin wing failure
Boomerang explosions

etc etc etc..........

Looking at the above list, it is certainly not the chinese jets being singled out. Every manufacture has problems. While FEJ's seem to be having more than their share lately, they are also selling huge numbers of jets, AND!!!!!!!!!!
I think this is something very important to consider....

The average jet modeler has changed significantly. In the past when we HAD to build our jets, we knew we were solely responsible for the integrity of the airframe, when the first ARF's came out, we still checked everything. Today, many people are content to buy, assemble, and fly. The maintenance of past years has decreased and the complancency level of many modelers had increased.
I have seen models have wing failures because the wing bolts were not tightened before flying, the wing had an oscilation and that caused the spar to fail. I have seen models fail because surfaces were not checked prior to flight and servo mounts had broken loose.
There can be SO many causes for failures. I myself have gotten worse at checking everything over through the years because the airplanes have become so easy to use. I do take my winters to go through everything as complete as possible though.

The recent FEJ wing failure sucks, and it certainly looks like the wing could have been built stronger, but at the same time, I don't know of ANY manufacture that would replace an airplane in those circumstances. All the big name companies (great planes, horizon, etc) clearly state that their product is warranted from any defects or problems and will be replaced AS LONG AS the original part is returned in unused condition. I've lost 2 airplanes over the years due to airframe failures, both were Great Planes products, and Great Planes wouldn't even say sorry for your loss much less do anything about it....

I lost 2 expensive airplanes when I was flying pattern due to transmitter failures. The failures were ADMITTED by Futaba as being 100% their fault in the transmitter, my transmitters were replaced, and they did step up somewhat by giving me a better model radio, but it nowhere near covered the $3000 loss of aircraft.

Pete,
You could lose an airplane due to ANY number of reasons, thumbs, midair, birdstrike, radio failure, structural failure, engine flame out, etc, all you can do is check the airframe over as best that you can, and enjoy it. Your fly eagle Rafale could come apart, so could my BVM Kingcat, if they both came apart, guess which one would get the blame laid on manufacture, and which one would get the blame laid on the pilot. The circumstances could be identical for both failures, but nobody expects it from BVM. If you are worried about flying your FEJ model because of the crashes that are publicized on RCU, you will never enjoy it. So you could sell it, and buy a BVM product, but in the end, are you going to feel that much more comfortable with it and the extra dollars spent knowing what all the different variables that can cause the loss of an airplane potentially are?

I don't know, I am working on my Liberty, seeing threads like the F15 one do worry me, but I was also in the process of building my Super Bandit when the wing failed on one in Jersey 5 years ago, that had me worried as hell about my Bandit, in fact, I STILL think about that when I fly my Bandit today, thanks to the cost of the airplane and where the Canadian dollar was when I bought it, I have $16,000 Canadian tied up in that Bandit, I'll have under $5000 in my Liberty, guess which one I'll be less concerned about in flight?

All you can do is fly them, if you are worried about them all the time, you'll never have any fun and you might as well send me the Rafale back, I'll fly it for ya
