Tamiya Raybrig NSX Concept GT - #58598 (Radio Controlled Model Review)

1/10 Scale Electric Touring Car - TB-04 Chassis:

  Released by Tamiya on November 8, 2014, this TB-04 Self Assembly RC Model, is of the Raybrig NSX Concept GT that raced in the 2014 Japanese Super GT Series.

  The Lexan body shell in this kit is a realistic representation of the super sleek lines of the original Raybrig NSX Concept GT. An ESC, Motor, Battery, Charger, Paint and Radio Equipment must be purchased separately.

  The 4WD TB04 Chassis is the worthy successor of the TB03 and has the same centre line drive shaft configuration, but with the motor moved to a rear horizontal position.

  It also shares the same double wishbone, independent suspension parts as the TB-03, TA-05 Version II and TRF (Tamiya Racing Factory) 416/417 series chassis.

  The design of the TB-04 Chassis also employs, sealed oil-filled gear differentials, coil spring over oil filled dampers, bell-crank steering and comes with a full set of steel shielded ball bearings.

  For me, the inboard, cantilevered front suspension system of the TB-04, is overly complicated, but by all accounts, seems to work well.

  To get the best from the Raybrig NSX Concept GT, it needs to be fine tuned to improve grip under acceleration and hug the corners at high speed, without slipping off the track. Small adjustments can make a Big difference and our simple to understand, step by step procedure, will guide you to the best Set-up for your driving style.

Buying a Used Tamiya Raybrig NSX Concept GT
Touring Car (and What to look for)


   Buying a used Tamiya Raybrig NSX Concept GT 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 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 Tamiya 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 Tamiya 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 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.

   If the body shell of your Tamiya Raybrig NSX Concept GT 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 Raybrig NSX Concept GT 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 Raybrig NSX Concept GT Touring Car model at a competitive level, I would also recommend you obtain and fit titanium pivot shafts, turnbuckles, tie rods and steering rods.

   On Belt driven models, the Drive Belts need checking at regular intervals for wear, tension and damage. If deemed necessary, adjust the tensioning pulley until the belt can be depressed in the centre by no more than around 5mm. If the belt was slack, also examine the drive pulleys for wear. The teeth should provide a well seated fit for the belt teeth and not be rounded on the corners. If the belt teeth do not fit snugly, change the pulleys as soon as possible. For top level racing it may be prudent to replace all belts and pulleys after each race meeting.

   For Gear driven models, 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 back yard, 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 Raybrig NSX Concept GT 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 Tamiya Raybrig NSX Concept GT 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 Tamiya 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 Raybrig NSX Concept GT model and good racing.

Hints and Tips

Tires for RC Models

Rubber Tires:

   Rubber Tires ALWAYS should have either soft sponge or rubber inserts. They will not function as they should without them. And if you are totally serious about your racing they should be glued to the rims.

   You should also have at least three different compounds (Soft, Medium and Hard) for varying track temperatures in On Road tarmac racing Touring cars and varying pin sizes for carpet and Off Road racing Buggys and Trucks.


How to Mount Rubber Tires onto Wheels/Rims.

   Before mounting your Tires, I would recommend talking to the more experienced racers at your local club, as to what inserts they use. Even the top level racers rely on a bit of local knowledge on tracks they have never raced before.

1/   Once you have decided what inserts to use, position them inside the Tires ready to go onto the rims.

2/   You will need strong fingers to pull and maneuver the Tires over the rims, so you may need the help of an adult. I would recommend NOT using metal Tire levers or a spoon as they can not only damage the fragile plastic rims but can also put small tears in the rubber, that could cause problems later.
   The technique I recommend, is to first of all hook the Tire on one side of the rim, then using the thumb and forefinger, grip the Tire and pull it upwards and over into position around the middle of the wheel, then over to its final position on the far side so that the beading is seated in the spigot. then position the near side beading in the opposite spigot making sure the sponge (or rubber) insert is not trapped and positioned centrally.

3/   You have the option of either gluing or not gluing your tires in position. If the track you race at is not too grippy you can get away with it, but on high grip tracks there is the possibility the tire might pull away from the rim and ruin your race.
My recommendation is to glue them.
   Superglue is the thing to use. To do this, carefully pull the beading out of its seating, put on a spot of glue, then quickly push it back down. repeat this at least 6 times around each side of the wheel.
Superglue can be dangerous, so this is best done by an adult.

Hints and Tips

Wheel Balance

   The day I passed my driving test at the young age of 17, the first thing I did was to drive over to my girlfriends house and take her out to a long straight stretch of road close by, where the boy racers would often congregate. No one was around that day, so the road was relatively quiet. I slowly went through the gears and we were soon up to 65 with no problems, but as we got closer to 70, my hands began to sense a small vibration on the steering wheel. By the time we hit 75, the steering wheel and the whole car was vibrating wildly. My girlfriend was hysterical, screaming for me to "slow down!" I did of course and tried to calm her down.

   Back home I told my dad what had happened. He then reminded me that just the week before we had put on a new set of front tires and suggested the wheels were probably out of balance. Sure enough, after the wheels were re-balanced, at 85, 90, the car was steady as a rock and drove perfectly.

   As I got deeper into RC, that memory returned and I realised to be more competitive I would have to balance all my wheels.

How I Balanced my Model Car Wheels


   Wheel balancing equipment for RC cars is now available on line and from most RC model shops, but back then I had to make my own using the rear end of an old Tamiya F1 car.

   With the insert fitted and the tire mounted and glued, the wheel was then bolted onto my home made balancer and while holding the balancer tightly, I spun the wheel vigorously. Invariably it would vibrate to some degree. To balance the wheel, I would next allow it to settle, then turn the wheel through 90 degrees and again allow it to settle. Obviously the heavy side of the wheel would drop to the bottom due to gravity. Once satisfied I made a mark on the rim with a felt tip pen at the top of the wheel where it came to rest. Removing the wheel, a small amount of plastic resin was then pressed into a recess on the inside of the wheel, on the side where I made the mark. The whole process was then repeated until I was totally satisfied. The final vigorous spin was always virtually vibration free.

   I was amazed just how out of balance some of those wheels were and how much a small thing like that can make a difference on the track.
