I personally have flown a the Vmar stinger for almost a year now, an am glad to report no problems. When I recieved the plane I ca glued all the joints as I normaly do and all is good. I also built my own wing joiner as I heard that the wings like to fold up. This is a great plane and would recomend it to anyone. I am using the vmax 46 engine and love it. It is very predictable and I never had one engine flare out.
