A string tied to your car gives better control than a stock 27mhz radio. You'll love a 3S then. I would still verify temps periodically with a quality temp gun though and compare the numbers so you know where your at. Especailly when you first set it up.
Not bashing on the telemetry stuff I just don't have any use for it, but it is kind of neat.
