I left the hobby for about 12months, mainly for 2 reasons, the first reason was money, for young people like myself and other young people is that when u start Rc, i basic rely in birthday presents and christmas, which is pretty funny but thats cause i didnt have a job back then. Also most of the people had all the new gear and equitment that had just come out and you struggle to win with the gear you already. and the secound reson is the FUN of the sport, not really fun losing all the time, people hitting you etc.
But now i have a job, got some money together and now back into the hobby racing 540 with my mates and having a great time, which is the main oart of the hobby i enjoy.
