The Basics

Here you will find some introductory information into the world of RC racing

What is RC?

RC is short for radio controlled (or some may say remote controlled).  Essentially the driver holds what is known as a ‘transmitter’, which sends a radio frequency to their vehicle to make it accelerate, brake and steer.

Vehicle scale

Radio controlled vehicles come in a range of scales (size) from the tiny 1/32 scale through to 1/5 and larger.  RC racing is generally done with 1/10th or 1/8th scale vehicles. At Chargers, we race 1/10th scale only.

Off-road vs On-road

As the title suggests, there are two categories of RC racing being either on-road or off-road.  On-road is generally done on a completely flat high-grip asphalt track consisting of long straights, tight bends and chicanes.  Racing is fast paced with hard braking and tight turning.  RC Drag racing is another form of on road racing consisting of a long flat straight.

 

In comparison, off-road racing is generally done on a dirt track, with jumps, tabletops, berms and overpasses.  Racing is fast but grip is lower and greater skill is required to keep the vehicle pointing in the right direction.

 

While the track at Chargers is sealed with Sic Surface, it is considered an off-road track.

Electric vs Nitro (fuel)

RC cars are either electric powered or nitro (fuel) powered.  Both have their advantages and disadvantages and both offer a different racing experience.

 

Electric powered vehicles have a LIPO battery (usually 2 cell or 7.4v) and are quiet, light, clean and responsive.  A fully charged battery will generally last around 15 minutes of racing before needing to be recharged.  Electric cars are less expensive to purchase and maintain.

In comparison, nitro vehicles are more like a 'real engine' and require a high degree of maintenance and tuning to keep them running at their best.  A nitro vehicle can run a lot longer with regular pit stops for re-fuelling.  Nitro vehicles are generally 1/8th scale and are noisy - but that is the attraction for many who race them.

At Chargers, we run electric vehicles only.

Vehicle types

Within the types of vehicles, there is also classes and you will often hear the terms 'stock' or 'modified' used when describing a 2WD or 4WD vehicle (mostly buggys).  The only difference between the vehicles is the type (or turn) of motor used and the ability to alter the timing of the motor electronically through the Electronic Speed Controller (ESC).

Stock vehicles will use a 17.5T motor for 2WD buggies and a 13.5T motor for 4WD buggies.  For competition racing, motors must be on the ROAR approved list.  The ESC must also be set to ZERO timing, otherwise referred to as 'blinky' mode as the power LED light on the ESC will blink to indicate to officials it has ZERO timing active.

In comparison, modified vehicles can use any motor and alter the timing of the ESC to get high RPM output from the motor.  Often racers will use 10.5T motors or lower, giving the vehicle high top end RPM (meaning more speed).

At Chargers we run 2WD stock and modified, 4WD stock and modified and stadium truck classes.  We also have a 'Run What Ya Brung' class which is suited for beginners/juniors and as the name suggests.....anything goes so long as it is 1/10th scale electric.

Stock vs Modified

Within the types of vehicles, there is also classes and you will often hear the terms 'stock' or 'modified' used when describing a 2WD or 4WD vehicle (mostly buggys).  The only difference between the vehicles is the type (or turn) of motor used and the ability to alter the timing of the motor electronically through the Electronic Speed Controller (ESC).

In comparison, modified vehicles can use any motor and alter the timing of the ESC to get high RPM output from the motor.  Often racers will use 10.5T motors or lower, giving the vehicle high top end RPM (meaning more speed).

At Chargers, we run both stock and modified race classes in 2WD and 4WD buggies.  Our stadium truck/truggy class is combined and racers will generally have a 'modified' setup.
