At Surrey and Hants on Sunday we have a heat for the Novice/Junior's and there were 6 of them, ranging from 6 years to 11 years of age.
Mixture of cars used from Vega, B4.1 RTR, Losi 22... so now real lack of kit. I think we've all gone on the fact that a quality car does have less issues, and when your running two kids AND yourself at a meeting you do not want to be repairing cars!!!
As a father myself and back after a 20 year break I was shocked at the lack of kids, that's why we always run a kids race as a stand alone.
They have zero pressure and crash and bash about like no business. As far as I can recall, only two cars had minor breakages over 4 rounds and 3 legged finals. Most of the cars top end is tweaked down though which helps.
Good luck with trying to get the kids racin'
