Buying a Used Kyosho V-One R4s
Touring Car (and What to look for)


   Buying a used Kyosho V-One R4s Nitro Touring Car, 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 road.

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

Dampers
   When you receive your used Kyosho Touring Car, 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 Kyosho 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 Kyosho V-One R4s 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 V-One R4s 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 V-One R4s Touring Car model at a competitive level, I would also recommend you obtain and fit titanium pivot shafts, turnbuckles, tie rods and steering rods.

   Drive Belts need checking at regular intervals for wear, tension and damage. If deemed necessary, adjust the tensioning pulley until the belt can be depressed in the centre by no more than around 5mm. If the belt was slack, also examine the drive pulleys for wear. The teeth should provide a well seated fit for the belt teeth and not be rounded on the corners. If the belt teeth do not fit snugly, change the pulleys as soon as possible. For top level racing it may be prudent to replace all belts and pulleys after each race meeting.

Spur Gears
   Gears are a weakness on all Touring Car 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 Nitro Engine 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 Nitro Engine mount and remember to check them for security after every two or three runs.

   Ball joints always cause problems. For top level Nitro Touring Car 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 V-One R4s 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 Kyosho V-One R4s 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 Kyosho Touring Car 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 V-One R4s model and good racing.

Hints and Tips

Tires for RC Models

Sponge (Foam) Tires:


   Sponge Tires can be purchased either pre mounted, glued and trued on the rims, or separately. Fitting the Tires onto the rims can be messy, so here are a few tips to make it a bit easier.
   If you are fitting new Tires on old rims, make sure the old sponge Tire is completely removed. To do this, I recommend using a wood lathe and apiece of wood, at least 300mm long and more than the width of your wheels, with medium grit emery paper stuck to it ... sand paper will also work, but emery is harder wearing ... This will also be used for truing a wheel. (Described later)

How to Mount and Glue Sponge Tires onto Wheels/Rims.


1/   Mount the Tires on the rims. Make sure they are reasonably tight on the rims, too loose and you might have problems.

2/   I find this to be easier if either in the lathe, or on the car itself. (but be careful with that glue)
  Using your thumb and forefinger, lift up the Tire off the rim, then using a small spatula or a thin piece of rigid wood or plastic dipped in glue (I recommend Evo-Stik, Impact Adhesive) slip it in the gap, making sure both the Tire and the rim are smeared. Then lower the Tire back onto the rim and press it down. Turn the Tire approximately 60 degrees and repeat.

3/   Depending on the width of the Tire you may need to repeat the process on the inside also.


How to True Sponge Tires.


   Truing Sponge Tires is essential if you are serious about racing competitively. To do this you will need the piece of wood, as described earlier and a good pair of vernier or digital calipers.
   Sponge Tires will always wear unevenly, weather you race on Carpet or Tarmac. The outside wheels will always end a race smaller than the ones on the inside, so after each race I recommend swapping them over (unless you are fortunate to have a new set for each race) and dont forget to adjust the steering trim on your transmitter before the next race.

1/   Before starting, check each mounted Tire for diameter and order them smallest to largest. Start with the smallest and mount it in the lathe.

2/   Make sure you are wearing safety glasses before you start this procedure: Lay the sanding wood under the Tire so that it can be pivoted up from behind onto the Tire. Start the lathe spinning, so that as you stand infront of the Tire, it is rotating downwards. Slowly lift the sanding wood and try to hold it ridged as it comes up against the Tire. There will be a high point on the Tire that if you hold the bat rigid enough will eventually wear down until the Tire appears completely concentric. at this point stop the lathe and measure the diameter on the inside and outside of the width. If needs be, repeat the process until satisfied.
Repeat for each Tire, matching them in pairs for diameter.
If considered necessary also trim the sides.

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.
