Things to do while RC car bashing Some people run a speed test while bashing their RC cars, but that provides a minimal improvement in driving skills. Check here for a speed meter. One good thing about RC car bashing is that you Don’t really need to set up the car as precisely as you would set it up for a race for you can bash freely, usually with no competitor. Even your car is not running very straight, you can still control it for a certain degree. During RC car bashing, you can feel very relaxed as you can stop at once. You are not forced to complete the current round.
