I've heard at least 8 people on these forums complaining about firying issues with their QC2's without running the max. ESC turn limit. That was around 5 months ago, so things may have changed.
I am a Novak guy, but I don't bow down to Novak and worship them everyday. I would be happy to own something LRP, but I just can't be convinced after all these problems that arise with their products such as, faulty Sphere/Neo, QC2 and the A1 line of their ESC's. Don't quote me on that either, because that's all coming from what i've seen on these forums.
Get the GTX
By the way, whereabouts are you ordering your GTX/QC2? The GTX is $10 cheaper then the QC2 on Tower.
