Hi Cristophe
Sorry for your loss and unfornuately we are seeing this happening in several ARF planes regardless of the manufacturers. The issue here is that we can't make any control on that because the wings or rudders are already finished and ther is no control if the spars have been properly glued or not.
The lack of quality control in these factories is obvious and I mean ALL ARF manufacturers. The least they could do was offering a really GOOOOOOOOD deal in the plane.
The amount of glue used is unacceptable for the plane, maybe the glue can was low and they let it pass. I have a Feibao F18 and I also have several issues regarding gear and stuff, but the glass fiber is great.
Maybe we should buy the planes with a X-ray certificate
regards
Nuno
