Lots of good wings to pick from out there,
Some work better than others and some last longer than others. Of course if you're always landing on your wing, it's probably not going to last long. If you never crash, even a weak wing can last. Just depends.
The JC high down force can take a pretty good beating and gets the job done. Not sure if it's the best functional wing out there.
The Losi 8 wings seem to work really well, but I had some that lasted and some that broke on the first crash. Not sure if they had a run of different plastics or not.
The new Up-Grade wing looks good and seem pretty durable. Now that they have the Fluro Yellow, I'll probably try one.
The JQ wing has a very unique look that I like. Don't know if it's good, but many people say they work well.
THe MP9 wings seem to be pretty durable and seem to work well. Just started using those to try a different wing.
There's plenty to choose from out there
