Buying a Used Schumacher Rascal Micro Truck (and What to look for)


   Buying a used Schumacher Rascal Micro 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 Schumacher 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 Schumacher 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 Schumacher 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 Schumacher Rascal Micro 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 Rascal Micro 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 Rascal Micro 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 Rascal Micro 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 Schumacher Rascal Micro 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 Schumacher 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 Rascal Micro model and good racing.

Hints and Tips

Bearing Seals

   If you were to ask anyone with a modicum of experience in RC, they will tell you that the best modification you can make to a basic RC model, is to add a set of ball bearings.

   Quite a few of the entrance level models at the time this article was written, come with plastic and sintered brass bushings (ring type bearings). If these bearings are installed in the model and coated with grease as advised in the car manual, dust and grit can be caught in that grease and be dragged into the bearing where it can abrade the shaft that spins in it and it won't be long before it becomes a very sloppy fit, causing all kinds of problems.

   But what should you look for when buying bearings? There are a number of types of seal used on ball bearings and there is much debate concerning which is the best for RC.

   Rubber and Cork bearing shields are two of the more common types available, but although they are very effective when it comes to preventing dust and grit entering the bearing, they also create more drag in the bearing due them rubbing against the bearing to create friction. For this reason, if I wanted to race my model at any level and that model was fitted out with rubber or cork shielded bearings, I would change them ASAP.

   Steel and Teflon bearing shields may not be as effective as the rubber shielded versions, but they don't rub on the bearing, so little or no friction is created. The problem with this kind of bearing of course is that they need much more maintenance and are often more expensive.

   Basic shop bought bearings generally come packed with grease for their lubrication. However, if you want to have your bearings spin freely; grease is not the best thing to use. So, before you install your new bearings in your car, the first thing you need to do is clean out the grease with something like isopropanol and replace with thin oil.

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.
