I reset my Quantum and I'll have to wait until Thursday to test it out to see if it goes back to making time. Either way since I have 2-4 big to very big races coming up within the next 5 months the new one is going in after I confirm that the original is either making run time or needs to be sent in. I guess for me ESC's having problems is just a part of racing, I've seen it happen so often. When one of the big dogs ESC's go down you almost never hear about it unless you're Kevin and in on all of the inner circles. Hah, got you. LOL, busting a gut LOL. Seriously, so many people are having success with their LRP Quantums and V 7's that I wouldn't worry about it if you guys have or were thinking about getting one. The car is so much easier to control, kind of like telepathy and I noticed increased run time (about 20sec) in 12th mod over my Cyclone. They all make some good stuff so when something goes I try not to sweat it. Best advise for servos, rx's, ESC's, crystals.... have a spare, preferably a duplicate spare so that you can keep the same performance.-Dave
