After crashing my Blade 500x in September of 2013 I had wanted to get a T-rex 500Pro DFC to replace it. Unfortunately things kept getting in the way. In June of 2014 I finally got it. Out of the box it is nearly as nice as the 500x with tons of upgrades was. To me, it really feels about the same as my upgraded 500x.
