All I have to say is that I like them both. Untill you need to repair them. My orginal GT7 I have had no problems with. My new Q2 worked fine untill I changed the settings for modified (turned on the drag breaks and turned down the punch) and then tried to switch the settings back. The problem 1 was that if I turned down the punch the throttle acted like a on/off switch. As long as I has the highest punch it was fine. Problem 2 was when I tried to switch everything back for stock, I couldn't turn off the drag breaks. Since it was brand new I had my store send it back, four months later it has come back and they say there is nothing wrong with it.
Nice.
