I know this is an old post but I believe a gyro is definitely a good thing for your car. I come from a heli background and back in the day helis did not have a gyro. Near impossible to fly one in a circle let alone in 3D. Just like back in the day of rc cars, they all had mechanical speed controllers, not electronic speed controller. So Id bet back then when the modern esc came on the scene, people were probably complaining about it being unfair or not up to professional standards. Id also be willing to bet those same people now have esc and not the mechanical ones. [>:]
