Tamiya XBG RevStorm - 43534 (Radio Controlled Model Review)

1/10 Scale Nitro Truck/Truggy: TNS-T18 Chassis

  Released by Tamiya on May 31, 2008, the 4WD XBG RevStorm Truggy - # 43534 - is No.34 in the Expert Build Factory Assembled Glow-Engine RC Car Series and is based on the TNS-T18 chassis, with an FS-18FD engine.

  The model is shaft driven, on an alloy plate chassis, with gear type differentials, coil spring over oil filled dampers, dogbone drive-shafts, bushings and some ball bearings.

  Like the majority of Tamiya RC models, this model comes with plastic and sintered brass bush type bearings, that after a short while, when dust and grit get into them, actually abrade the metal shafts that spin in them - our recommendation is that these should be replaced by steel shielded ball bearings ASAP.

  To race the Tamiya RevStorm, it requires time and patience, to tune and adjust for improvements in handling and steering ability and to get the grip you need to stay on course when manoeuvring around tight, slippery corners. A little can be a lot when it comes to changing your cars settings and our easy methodical directions will guide you to the best Set-up to help you win and keep you winning.

Buying a Used Tamiya RevStorm Truggy (and What to look for)


   There are essentially three reasons you might want to buy a used Tamiya RevStorm Nitro Truggy; you may be a collector, looking to restore and display it; restore and sell for a profit; or simply restore and race an iconic vintage model. Personally, I used to get a buzz out of restoring an old clapped-out model, installing modern day electrics and maybe a few hop-ups, then showing the gang at our local club, just how competitive those old models could still be.

   Cheap, pre-loved bargain models, parts and spares are always coming up for sale, but once you have made your purchase, the one thing you will always need, is an instruction manual. If not supplied with your purchase, they can often be downloaded from the Tamiya website, or purchased separately on eBay. With an instruction manual, any problems with your model Truggy you may discover, can easily be fixed.

Make a General Visual Inspection

Dampers
   When you receive your used Tamiya Truggy, 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 Tamiya 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.

Check the Body-Shell

   If the body shell of your Tamiya RevStorm 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 RevStorm model, fit an under guard to stop dirt and gravel entering the chassis.

Drive Shafts and Turnbuckles

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 RevStorm Truggy model at a competitive level, I would also recommend you obtain and fit titanium pivot shafts, turnbuckles, tie rods and steering rods.

Examine the Drive System

   The gearbox of your used Truggy 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 Truggy 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.

Pinions and Spur Gears

Spur Gears
   Gears are a weakness on all Truggy 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.

Don't Neglect the Ball-Joints

   Ball joints always cause problems. For top level Nitro Truggy 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.

Steering Servo and Servo-Saver

Servo Gears
   The RevStorm 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.

Stabilizers

   If body roll on your Tamiya RevStorm 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.

Don't Forget those Bearings

Ball Bearings
   If your used Tamiya Truggy 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 RevStorm model and good racing.

Hints, Tips and Information

Roll Center

   One of the least understood settings on RC model cars is concept of roll center. The simple definition of roll center is a point in space that the chassis rolls from side to side as the car maneuvers around a corner.

   To calculate roll center you have to consider things like the height of the axles, the inside and outside camber link positioning, the length of the suspension arms and the location of their inside pivot point. Sounds complicated doesn't it - and in truth - it is.

   On all RC model cars, most of the cars weight is above the chassis and the center of gravity of the car is not only from front to rear, but also from top to bottom. This point is called the "true" center of gravity and is the point around which the weight of the car will want to roll from side to side, but it is the roll center of the chassis that the chassis will actually roll around, not the center of gravity.

   Once you have determined the positions of roll center and center of gravity, you can calculate the "roll moment". It is this that determines how easily the chassis will roll from side to side.

The Effect of Roll Center on your Car

   But what does all this mean? I hear you ask. Well, it gives you some insight to what changing the position of your camber links can do to the way your car handles.

Hints, Tips and Information

Getting into RC

   When I first got into racing RC, all I had was a three year old clapped out Tamiya Boomerang, a silver can stock motor, three step mechanical speed controller, two 1400Mah stick batteries and basic Acoms stick transmitter.

   I was the newbie and most of the guys I was racing against had all the latest models, modified motors, matched batteries and top spec radio equipment, but I was still beating them easily. Why? The answer is simple:
