Buying a Used Kyosho Inferno ST-R Truck (and What to look for)


   Buying a used Kyosho Inferno ST-R Nitro Truck, 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 Kyosho website, or purchased separately on eBay. With an instruction manual, any problems with your model Truck you may discover can easily be fixed.

Dampers
   When you receive your used Kyosho Truck, 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 Inferno ST-R 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 Inferno ST-R 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 Inferno ST-R Truck 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 Truck 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 Truck 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 Truck 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 Truck 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 Inferno ST-R 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 Inferno ST-R 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 Truck 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 Inferno ST-R model and good racing.

Hints and Tips

Painting a Lexan Body Shell.

   Most RC Model kits come with an unpainted, clear Lexan plastic Body Shell you yourself must prepare and paint. This type of Body Shell is painted on the inside and special spray or brush on Polycarbonate Paints MUST be used.

   The beauty of this is you can go wild and show off your artistic ability, or simply choose your favourite colour and add some choice decals later.

   This article is for those who have never done this kind of thing before and need some basic guidance.


   Firstly, cut off the waste from the body shell with sharp scissors. If required finish off the rounded wheel arches with smooth sandpaper wrapped around a drinks can.

   Any holes for body posts must also be drilled before painting. Place the clear body shell over the model and adjust the posts so the shell is in the desired position. Where the posts touch the shell make a small dot with a marker pen.
Next, pierce small holes in the shell where the dots are from the inside. Place the shell on an old piece of wood and drill the post holes, again, from the inside.

   The next thing to do is clean it inside and out. Any small amount of impurity such as oil or grease could impair the adhesion of the paint.
For this, fill a bowl with water and use a small amount of washing up liquid with a soft sponge. Never use a scourer. Rinse well to ensure no residue remains.

   Most Body Shells come with a set of sticky back paper masks for the windows etc that are positioned on the inside. If not supplied, you will have to either make your own, or use masking tape. Run your thumb nail around the edges of each mask to ensure contact paint can creep into any open area and easily ruin your hard work, so please be vigilant.

   Tip: To protect against paint spilling out onto the outside of the body shell, use masking tape around the outside edges and wheel arches.

   Now you are ready to begin applying your paint. Find a well ventilated area and if spraying, use a breathing mask.
Three or four sprayed, or at least two brushed layers are recommended allowing around thirty minutes between layers.

   Once the paint is fully dry, to protect the paint from scratching, spray or brush over it with one or two layers of clear plastic varnish.

   When the varnish is completely dry, carefully remove the window masks. If necessary, use a modelling knife to lift an edge to grasp between your thumb and finger DO NOT RUSH.

   Decals can now be placed on your body shell. So they adhere better I recommend any square edges are rounded. This reduced the tendency for them to peel off.

Hints and Tips

Sway Bars

   On most forms of RC model cars, Sway Bars, also referred to as Stabilizers, Torsion Bars, or more commonly in some parts as Anti Roll Bars, are often nothing more than a short length of spring steel, clamped to the chassis or sometimes the gearbox of the car, extending out to the lower wishbones direct or connected to the wishbones using short adjustable or fixed length links and ball joints, depending on their position.

   The principal behind the Sway Bar is simple. As the car enters a corner, weight is transferred to the outside wheels, the chassis rolls due to inertia and the suspension dips and grip on the inside wheels is reduced. In an effort to counter this dipping effect and transfer some grip back to the inside wheels to improve traction as you exit the corner, the sway bars transfer the dip of the outside, to pull down the inside wishbones, improving grip on the outside wheels and improving overall stability.

   Sounds complicated I know, but for some tracks sway bars can be a useful tool when you have exhausted all other options to correct your handling problems.

   Tuning your Sway Bars is quite easy. Some manufacturers do offer colour coded tuning sets with varying thicknesses of spring steel wire, but the best way is to change the position the bar is attached to the wishbone, or on some variations you have the option of positioning the link on the Sway Bar itself. By simply moving a small collet clamped along the short length of the bar. Closer to the central pivot point reduces the leverage of the bar and effectively increasing its resistance, further away from the pivot point reducing resistance. More fine tuning can be achieved by adjusting the length of the turnbuckle link (if available) to pre load the bar.

   Personally, before I ever installed any sway bars I would always try changing damper tuning springs and oil viscosity settings, especially if the track was uneven and bumpy, in which case the effectiveness of the bars was minimal if at all.

   For those more into Drifting, Sway Bars can be an easy way to fine tune your car. A single turn on the turnbuckle links can be a way to simply increase or decrease wheel traction that minute amount you need to get the perfect balance.

   For more on how to use Sway Bars check out our Set-up tips page linked below.
