Buying a Used Carson Dirt Attack XXL 6s Buggy (and What to look for)


   Buying a used Carson Dirt Attack XXL 6s Electric Buggy, or any used RC Model, has a number of advantages. It is generally cheaper than new, ready built and may come with a variety of expensive hop-ups already installed. Cheap, pre-loved bargains are always becoming available. However, depending on the age of your purchase, it may need a little tender loving care before you can take it out on the back yard.

   The one thing you will always need is an instruction manual. If not supplied with your purchase, they can often be downloaded from the Carson website, or purchased separately on eBay. With an instruction manual, any problems with your model Buggy you may discover can easily be fixed.

Dampers
   When you receive your used Carson Buggy, make a general visual inspection of the chassis, front and rear wishbones, suspension shock towers etc, for any broken parts that may need to be replaced. Then, take a screwdriver and box spanner and check each self tapping screw and nut for security, taking care not to over tighten.

   Next, for those Carson models with oil filled shock absorbers, remove them from the chassis and dismantle the coil springs. The damper shafts should push in and pull out with a smooth action. If you feel a jolt as you change direction, this means the oil has leaked out and must be topped up. At the same time, change the O-Ring seals to prevent more leakage. Also check the damper shafts for damage. If they are scratched, change them as soon as possible.

   If the body shell of your Carson Dirt Attack XXL 6s is broken, ripped or damaged in any way, this can be easily repaired with rubber solution glue. Also, for added protection and if available for your Dirt Attack XXL 6s model, fit an under guard to stop dirt and gravel entering the chassis.

Titanium Turnbuckles
   Examine the drive shafts for wear and replace as required. If possible, change them for titanium. The steel shafts wear and bend too easily.

   If you intend to race your Dirt Attack XXL 6s Buggy model at a competitive level, I would also recommend you obtain and fit titanium pivot shafts, turnbuckles, tie rods and steering rods.

   The gearbox of your used Buggy should be opened up to check for gear wear and lubrication. A thin coat of grease is often used on internal gears and although this is fine for basic running around on the back yard, if you intend to race your Buggy at a higher level, this should be removed and replaced with racing oil (ZX1 or Teflon Oil). Of course, this should be reapplied after each race meeting.

Spur Gears
   Gears are a weakness on all Buggy RC models. Head on collisions can easily damage the gear teeth on nylon and plastic spur gears. Heavy impacts can also loosen the nuts or self tapping screws that hold the Motor in Position, allowing the pinion gear to pull out of mesh slightly and rip the tops off the teeth on your spur gear. To minimise this possibility, fit bolts with locking nuts to the Motor mount and remember to check them for security after every two or three runs.

   Ball joints always cause problems. For top level Electric Buggy racing, the plastic ball connectors should be checked and if deemed necessary changed after every meeting. A simple thing like a loose fitting connector popping off could easily end your race, so better safe than sorry.

Servo Gears
   The Dirt Attack XXL 6s steering servo is also prone to damage. In high speed crash situations, the fragile gear teeth of the servo can be broken off, rendering your expensive servo useless, so be sure to obtain a good quality "Servo Saver". Check out my Servo Information article.

   If body roll on your Carson Dirt Attack XXL 6s is a problem, handling can be improved with the use of stabilizers, anti roll or sway bars, stiffer tuning springs and, or, thicker silicone oil in the dampers.

Ball Bearings
   If your used Carson Buggy comes with plastic and sintered brass bushings (ring type bearings), check the shafts that run in them for wear. Dust and grit can get into these bearings and abrade the shafts. Therefore, you should replace them all with shielded ball bearings. If the model has been run with ring type bearings, you may have to change all the axles and driveshafts. For more information, take a look at my article, How to get the best from your Bearings.

   Finally, good luck with your Dirt Attack XXL 6s model and good racing.

Hints and Tips

Look after your Gears

   In RC there are a number of different gear teeth sizes we tend to use, based on two systems. Imperial and metric. The imperial system has sizes 24dp, 32dp, 48dp and 64dp. DP stands for Diametral Pitch and the number refers to the number of teeth per inch. The metric system has sizes 0.4m, 0.5m, 0.6m, 0.7m, 0.8m and 1m. M stands for Module and is the ratio of the reference diameter of the gear divided by the number of teeth.

   The different sizes are used basically for strength. 32dp gears larger than 64dp gears, therefore it stands to reason that the 32dp gears are by design stronger and for this reason are more commonly used on a number of entry level buggys and nitro models because of the higher torque levels involved. Also, the bigger the scale of the model, the stronger the teeth need to be.

   64dp and its metric equivalents are generally the choice of 1:10 electric on-road racers, because of its higher range of ratio options and smoother action in comparison to other sizes. On-road models are not as hard on the gears as off-road, so the weaker, small tooth size is not a problem.

   48dp and its metric equivalents tend to be preferred by 1:10 off-road racers, mainly because of their strength in comparison to the 64dp and smoother operation than 32dp. Off-road models need gears that can handle all the knocks and bangs, as well as heavy landings off high jumps.

   Setting your gears is the most important part of looking after your gears.

   Backlash is basically the gap between the teeth in mesh. The perfect gear setting must have a small amount of backlash. To achieve the best setting use a very thin sheet of plastic between the pinion and spur gear teeth as you press them into mesh. After tightening the motor mount screws, use your fingers to spin the spur gear and roll out the plastic sheet. If the setting is correct, there will be a small amount of movement (backlash) between the gear teeth before they catch. If the mesh is too deep, there will be no movement between the teeth, this will create friction and if you run them like this, they will grind together, wear and break. If the mesh is not deep enough and only the tips of the teeth are touching, the excessive backlash will soon damage and strip the tops off the teeth rendering the gears useless.

Hints and Tips

Ackerman

   So What is Ackerman?

   If you place your car on a table facing away from you and turn the steering to full lock to the left, you will notice the angle the left hand wheel has turned is more than that of the right hand wheel. That is the Ackerman effect.

   Moving your car to the edge of the table, with the wheels still on full lock, push it round a complete circle. What you will notice, is the diameter of the circle made by the inside wheel, is smaller than that of the outside wheel. This is a good thing.

   Consider what would happen if both wheels turned to the same angle. In this example, the inside wheel would have a tendency to drag sideways, making the car unstable and difficult to drive.

   The standard kit setting on the majority of RC Model cars, are generally pretty good for beginners, but when your experience increases, you will find out just what tuning your Ackerman can do for your driving style and why it can be helpful when setting up your car for any particular track.

   Some of the cheaper RC Models have fixed position steering links. Others have various methods to change Ackerman settings, like changing shims under the ball connector etc. These days, most modern cars allow you to adjust your Ackerman by lengthening or shortening the links by simply removing two screws and repositioning the links in relation to the front suspension arms.

   Lengthening the links, by adjusting the pivot points of the steering arms back towards the centre line of the rear axle, will give you Less Ackerman, providing you with more aggressive steering as you enter a corner. Useful on slippery tracks, to counter when the car tends to slide to the outside of the corner as you first turn into it.

   Shortening the links, by adjusting the pivot points of the steering arms more forward of the centre line of the rear axle, will give you More Ackerman, making cornering less aggressive, more predictable and improving car stability, better for high grip tracks, with smooth sweeping corners.

   How to implement these adjustments varies from model to model so you will have to refer to your manual for full instructions.
