I just wanted to give my 2 cents worth. I read a lot of these forums about the vmar stinger and am disapointed. I have had mine for almost a year now and love it. I also have the vmax 46 on it and love it also. I use Byron 15% and it runs great. I put this plane through the riggers and pull a lot of G's with it and so far it has preformed great. I was wondering for the people that are having all these problems with the stinger with the wings folding up have you built your own wing joiner? I did and so far so good. And do you give your aircraft a good preflight and postflight inspection. About halfway through the summer I noticed one of my ca joints on the vertical fin had come loose and that was about it. I contacted Richmond Rc about this and they were more than happy to send me a new vert fin which I declined because of the easy fix. So far so good. I would recomend to anyone looking for a trainer or just a fun plane to go and play with.
