Hi, would you consider to add an additional rule for tire replace like real car racing or the majority of RC car racing (club race level like this series in TRC 2011) in other countries. For example, any wheel (attached with tire and insert) require for replace due to the reason of broken. Racer can replace it in one old wheel to one new wheel basis. And this wheel change will result 10 seconds add up on his best qualify time. That mean, one wheel replace=10 seconds, two wheels replace=20 seconds...and so on. This is a fair rule for those racers who didn't replace their old rubber with new rubber as will takes advantage.
On the other hand, how about serious warning for those racers who like to bump into another car during racing. Every single bump into the front car by a car behind. The car behind will get a "stop and go" penalty.
Thanks so much! Everybody knows TRC is one of the best RC track in Hong Kong, including myself. Look forward to receiving your final confirm over the "tire change penalty", if you will execute it finally.
