ALL the big kids were at Fred Caterson Reserve on the weekend, even the pensioner big kids.
There were almost 200 of them, and they'd come from as far away as Tasmania.
They were there because Castle Hill offroad radio-controlled car club was hosting the annual NSW titles.
And like all aficionados of arcane pursuits, Castle Hill club president Richard Bagguley can spruik a good sales job.
"It's underground but it's quite large and a lot of people don't know about it," he said.
"It's a worldwide thing and is big in America.
"We've got about 50 members and started in 1987.
"There are also clubs in Ryde and St Ives.
"The technology is crazy.
"Cars can get up to 80-100km an hour."
Bagguley rattled off the different types of members; the old-timers referred to as the pensioners and the younger members, as his son once was.
"Then he got his driver's licence and found out about girls and that was it," he said.
The president and club member Chad Donnelly were there from Thursday, rolling the clay surface and preparing the jumps.
For the non-aficionados, classes were 2wd stock, 2wd modified and stadium trucks and there were qualifying races and finals on Saturday.
The 4wd stock, 4wd modified and short-course trucks had their qualifying and finals on Sunday.
For those wanting to know more, club meetings are held every first and third Sunday of the month at Caterson Reserve.
