Buying a Used Smartech Winner-Pro
Touring Car (and What to look for)


   Buying a used Smartech Winner-Pro 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 Smartech 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 Smartech 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 Smartech 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 Smartech Winner-Pro 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 Winner-Pro 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 Winner-Pro Touring Car 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 Touring Car 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 road, if you intend to race your Touring Car 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 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 Winner-Pro 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 Smartech Winner-Pro 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 Smartech 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 Winner-Pro model and good racing.

Hints and Tips

Caster

   Caster is basically the angle the steering kingpins or steering pivot points, leans back in relation to the horizontal when viewed from the side of the chassis.

   To test the effectiveness of your cars caster, place your model on a flat surface, point the front wheels straight ahead and push the chassis over to one side to simulate body roll when cornering. You will notice that as the car leans over, all four wheels also lean over in the same direction. Tires provide the most grip when the wheels are perfectly vertical and the full width of each tire is flat on the ground. Body roll pushes the wheels past the vertical and reduces the amount of tire contact. Now, if you turn the front wheels as if cornering and again push the chassis over, you will see that in this position, the front wheels are now more vertical, giving you better ground contact and therefore improved grip.

   Another effect of caster can be seen by disconnecting your steering servo and pushing your car along the floor. Because of caster and the kingpins leaning back, your car will naturally roll straight ahead.

   Obviously, the more body roll your car induces, the more positive caster you need to counter it. Buggys, Trucks and Truggys, because of their high ride height and long dampers have more body roll and therefore require more positive caster than on road cars, with their low ride height and shorter dampers.

   If you consider a corner as having three parts: An entrance, middle and an exit. Caster influences each of them.

   With a high degree of positive caster, as you enter the corner and body roll is at its greatest, steering is better. In the middle section, as body roll reduces, steering is less effective and some under-steer is induced, that will continue as you accelerate on corner exit.

   With a low amount of caster, steering response is improved in the middle section of low speed turns and will be more likely to over-steer on corner exit because of increased front end grip from the tires.

   Too little caster can result in difficult handling on corners and poor stability on the straights.

   Most modern RC model kits come with a standard caster setting that has been set for the best handling by the manufacturers. If you are new to the sport I would recommend you stick with this setting until you get a little more experience.

   Methods to adjust caster can vary from model to model. Sometimes it is as simple as moving the position of a plastic washer from one side of the top wishbone pivot bar to the other, or simply using a small clip. Models from some manufacturers often have specific caster blocks to change the angle and must be purchased separately.

Hints and Tips

Shock Mount Settings

   The combinations of Shock settings available on the majority of on and off road cars are far too many for this article to cover, so I will endeavour to explain some of the basics, that should give you some idea what these changes might achieve. Some of the settings suggested may not be available on all RC model cars.

   If you look at the lower wishbones of you model, you may see a number of holes alongside where the ball studs for the dampers are positioned. If you were to remove those studs on the rear wishbone and reposition them in the hole further out from the center of the car, the first thing you will notice is the ride height has dropped, this can be corrected by adding C spacers above the springs. The second thing you will notice is the shocks are more sluggish, this can be compensated by using thinner oil. If this adjustment is made on an off-road car, it can be advantageous for landing after big jumps, providing improved stability due to the increased hydraulic pack in the shocks (as described in my previous article). This setting can also improve the way cars handle small bumps and dips in the track, due to the softer static damping.

   Changing the mounting hole positions used by the dampers, on the wishbone or on the shock tower, will always change the angle the dampers lay. This angle is what changes the characteristics of the shocks in that they will react to different track types and conditions. The above example is just food for thought, for those looking to improve their cars handling in relation to any other settings, such as caster, camber, toe-in etc, they may have previously made on their car. The only way to really get to grips with this subject is through trial and error.
