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


   Buying a used Kyosho V-One S III 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 S III 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 S III 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 S III 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 S III 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 S III 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 S III model and good racing.

Hints and Tips

Wheel Balancing

   At the tender age of 17 I passed my driving test. Of course, the first thing I did was to dash over to my girlfriends house and take her out to a long straight stretch of road close by where the boy racers would often congregate. No one was around that day, so the road was relatively quiet. I slowly went through the gears and we reached 65 with no problems, but as we got closer to 70, my hands sensed a small vibration on the steering wheel. By the time we reached 75, the steering wheel and the whole car was vibrating hard. I remember my girlfriend screaming for me to "slow down," Which I did of course and tried to laugh it off.

   Back home I told my dad what had happened and he reminded me, that just the week before we had put on a new set of front tires and it must be the balance that is out. Sure enough, after the wheels were balanced, 85, 90, was not a problem, the car drove perfectly.

   So, when I got deeper into RC, that memory returned and now I balance all my wheels.

   These days, wheel balancing equipment for RC cars is available from most RC model shops, but back then I had to make my own using the rear end of an old Tamiya F1 car. Here's how I did it.

   With the tire and insert mounted and glued, the wheel was fitted onto my home made balancer and allowed to settle. I would then gently turn the wheel through 90 degrees and again allow it to settle. Obviously the heavy side of the wheel would drop to the bottom due to gravity. Once I was satisfied, I would then make a mark on the rim with a felt tip pen at the top of the wheel where it came to rest. Removing the wheel I would mix a small amount of plastic resin and press a tiny amount of this into a recess on the wheel on the side where I made the mark. The whole process was then repeated until I was totally satisfied.

   I was amazed just how out of balance some of those wheels were and how much a small thing like that can make a difference on the track.

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.
