I had a cefx photon . And the one thing that was cool but didn't like was the bottom mount motor mount it has flex and it was steal . Not to mention most motor end bells don't have a lot of depth for screws so I never stripped a gear or screw but with the aluminum its a concern I have. I'm a decent racer but still take big mas takes . I would prefer to see a 2012 style with heatsinks .
