A car collection under control

A car collection under control
Your pulse quickens as you work the controls, getting ready to take that last turn, sliding through the dirt as you show off what your new remote controlled car can do.
They are the theme of many a childhood memory, but for Bundaberg's Kieran Rasmussen there are still plenty of memories yet to be made in his RC garage.
"This is a remote control version taken to a new level. This is the extreme competition end of it, it's a part of a large number of RC hobby groups," he said.
"By the way,lipo 5000mah good for rc car,"

 Kieran was first introduced to the sport by his father as a ten year old, and five years later has now progressed to working with aluminium and titanium on the lathe in his dad's back shed, making his own parts.
"My dad had a few old ones from when he was young. We got them working, and that started it off. It's now progressed to a rather expensive collection of custom cars."
Kieran said that 'expensive' in this sport can mean rigs of around $5,000, with inexpensive being around $500. For someone looking to take up the sport, his advice is to start small and look around.
"For the average person that means going to the local hobby shop and look at what's on the shelf to find something you like.
"For me, it means 'that part looks nice, I'll build the rest.' That's my style, but it's different for everyone."
The competition side of the sport is something that Kieran is passionate about as well, making his machine to specifications worthy of a V8 supercar.
The black chassis in Kieran's hand competes in the 2.2 inch [5.58 cm] class, so named for the size of the wheels. Cars with a wheelbase up to 12.5 inch [31.75 cm] can compete in this class.
"You can have dual motor, single motor, and all that sort of stuff. It's the major class all around the world, and it's purely about obstacles and who can get up the biggest rocks."
The rock crawler is not just for racing over pebbles and stones. During competition these machines will crawl over boulders a metre high, racing through a series of gates in the fastest time.
This is where more control over your vehicle can give you a huge advantage, and Kieran said that having a good rig can make a big difference.
"Setup and weight placement are very important. More weight below the axle will give you more stability.
"Also important is the driver. The professional drivers in the sport are just incredible. You could hand them an out-of-the-box car and they would beat everyone."
That control is thanks to the remote in the driver's hand. The older style remotes were usually a giant brick-like controller with a huge aerial pointing forward. Two joysticks would give you control, with one for steering, the other the throttle. Kieran's is a little more advanced.
The remote in his hand more like a pistol, and the control it gives him is amazing.
"It gives me very fine control. You have the trigger which is your throttle, and then a wheel to the side which is your steering.
"For the rock crawlers, you can use up to four channels, depending on the class, which can then control other aspects of the car.
"This particular car has two motors, one on the front and one on the rear, and through the remote you can control how much power goes to each motor.
"All of that is done from your controller, so you've got a lot more that two joysticks on there."
Kieran is hoping to grow the sport in the Bundaberg region, because presently most competitions take place in Brisbane, and only a few are held in regional areas.
As for any other hobbies, Kieran laughed. "This takes enough of my money."
