Buying a Used Redcat Lightning STK
Touring Car (and What to look for)


   Buying a used Redcat Lightning STK Electric 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 Redcat 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 Redcat 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 Redcat 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 Redcat Lightning STK 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 Lightning STK 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 Lightning STK 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 Electric 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 Electric Motor mount and remember to check them for security after every two or three runs.

   Ball joints always cause problems. For top level Electric 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 Lightning STK 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 Redcat Lightning STK 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 Redcat 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 Lightning STK model and good racing.

Hints and Tips

On Road Drifting

   Drifting is the greatest fun you can have on four wheels, but it isn't as easy as it might look. There are lots of different methods and ideas on how it should be done and it takes lots of practice to get it right.

   On the street or in the parking lot, drifting is fine, but until you have had hours and hours of practice to master the technique, don't try it on your local race track. If you don't have the total control of your car, you will not make many friends amongst your immediate competitors.

   Controlled Drifting is a beautiful thing when done correctly and in this article I will endeavour to give you a few pointers on where to start. After that, your own personal style will soon blossom.

   As I mentioned before, there are a number of different ideas about drifting, but basically this is what you do.

   Consider a 180 degree turn. Enter the corner at speed, start to turn a little sooner than you might, then just before the apex, touch the breaks for a split second, enough to break the rear of the car free as you enter to turn. When the car begins to slide sideways, steer into the slide, increase the throttle, just enough to balance the car as it drifts around the turn. Coming out of the corner, steer the car straight and apply full throttle.

   Often referred to as a power slide, drifting is much more fun than the basic "Rounding" style, described in a previous article, but also takes more skill, not just in its execution, but in car set-up.

   A little "body-roll" is the thing to aim for when setting up a drifting car, but be careful. With too much body-roll, the car will be difficult to control and tumble sideways off the track. Too little and the weight transfer to the leading wheels will not be enough to induce the slide. A lot of trial and error, with tuning springs, damper oil, damper pistons, stabilisers, tires and inserts is required to get your car as you want it, but believe me, if you can get it right, it will be well worth all your effort.

Hints and Tips

Your First Race Meeting

   When you finally find a racing club near to where you live, that initial experience of stepping up onto the rostrum and looking down over the track can be very daunting. But soon, as the race starts, adrenaline will kick in and away you go. For the next five minutes, your focus is on nothing but getting your car around each corner, avoiding all the other cars on the track and just getting to the end of the race.

   Maybe your batteries dumped or you crashed and the car was damaged, perhaps you didn't actually come last, whatever happened, it doesn't really matter you are well and truly hooked.

   When the race is over, don't be afraid to ask the more experienced racers questions about setup, driving tips etc. They have all been where you are now and will be more than willing to help you. Show them your car, get some tips on tires, gearing and general set-up for the club track.

   Then, when you get back home, go through all your races in your mind. Try to identify the things you did wrong and figure out how to avoid those mistakes next time. Think about what all the more experienced racers told you and change your settings as they advised.

   Put down a few buckets or cones in the back yard to practice driving round, something that if you hit it won't damage your car. Get someone to time you for say ten laps and each day after school, try to beat that time. The adage, "Practice makes perfect" holds true in many things, not least the sport of RC racing and as your confidence increases, your racing skills improve and the trophies begin to line up on your bedroom shelf, you will one day yourself be the guy all the newbie's look to for advice and you will remember that day, you nervously stepped up onto that platform for the first time, looked down across the track and how your whole life changed in that fleeting moment.
