Those little RC cars really got me addicted. This time, I bought a dNano, a 1/43 RC car, which is smaller than mini-z. Beside doing some of my programming stuffs, I have been reading and studying about mini-z. I also got a chance to go to one of the mini-z track in Hong Kong. Of course, my skill could not compare to those racers (I was like driving a bumper car *^_^*; ) and thank you to one of them who has taught me a lot of what I should modify my mini-z in order to control it better on their track. After playing on the real track, I realized I really need to do some engineering study for car, such as toe-in, camber angle, ball diff. etc. (before I only knew I have to buy them, but no idea why I need them *-_-*;) It is a really amazing small toy…
