Interesting post impactplayer. Here, the better drivers are those who do the most practice and have the most track time. Off track financial situations are not really looked at. It is assumed that if you are able to have a hobby, especially a hobby that requires a high upkeep such as rc cars, that person or parents of that person are well off enough to support it. The fully sponsored drivers are what they are due to all the practice and track time they have put in. However, their income in most cases don't even come close to those who take up rc racing as a hobby.
