C'mon ThermalRD (is that really you in the picture?) you know that the TRX2.5 is a pain. You're just one of the lucky ones that has one that can idle for more than a few seconds. Why of all the engines it's just the TRX2.5 that has so many tuning issues. Yes, the tank contributes to the problems, does it mean I'm a tuning genius when I started the OS CVR .18 the first time and it idled for ever? Guess not, it's just a better engine to keep a tune and coincidentally I am no more a genius because the OS doesn't overheat with the standard T-maxx tank.
