Tamiya Porsche 911 GT3 Cup VIP 2007 - #58407 (Radio Controlled Model Review)

1/10 Scale Electric Touring Car - TT-01E Chassis:

  Released by Tamiya on April 22, 2008, this TT-01 Type E (TT-01E) Chassis based, self assembly electric RC model, is of the Porsche 911 GT3 Cup Cars that were used by private racing teams in the 2007 Porsche Supercup series. The Porsche 911 GT3 Cup VIP was specially maintained by Porsche and driven by invited guest drivers.

  The lightweight Lexan Polycarbonate body shell in this kit realistically replicates the distinctive shape of the car. LED headlights and taillights and decals of the gold and white stripes along with all the Porsche logos are included.

  The budget priced 4WD shaft-driven TT-01 Type-E (E for Enhanced) bathtub frame provides for a low centre of gravity and superb balance. Four wheel double wishbone suspension with coil spring over friction shock absorbers, combine with front and rear orbital gear differentials to give excellent handling.

  A fibreglass reinforced nylon upper deck and gear covers go to improve the chassis rigidity and 3-piece track rods provide smooth responsive steering.

  The kit comes with nylon/plastic and sintered brass bush type bearings that after a short while, when dust and grit get into them, actually wear into the metal drive shafts that spin in them - if you are building this kit to race seriously, these should be discarded and replaced by a full set of steel shielded ball bearings.

  To get the best from the Tamiya TT-01E Chassis, it needs to be fine tuned to hug the corners at high speed, without slipping off the track and accelerate smoothly under control. 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 Porsche 911 GT3 Cup VIP
Touring Car (and What to look for)


   Buying a used Tamiya Porsche 911 GT3 Cup VIP 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 Porsche 911 GT3 Cup VIP 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 Porsche 911 GT3 Cup VIP 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 Porsche 911 GT3 Cup VIP 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 Porsche 911 GT3 Cup VIP 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 Porsche 911 GT3 Cup VIP 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 Porsche 911 GT3 Cup VIP model and good racing.

General Information and Advice

   RC is one of those sports that can be simply bashing around the back yard, or taken to the extreme of National and International Racing: For those who would like to enter this world of miniature Models, here are a few basic Hints: Firstly, buy a Kit not an RTR. Then, if something does break on your model, the experience you gain by building the kit will give you some idea how to fix it.

   Radio Controlled Model Cars are easily broken. Wishbones, Suspension Shock Towers, Dampers etc are prone to damage, so make sure you have a good strong front bumper and never run your car without its Body Shell in place.

   The Steering Servo is also a weakness, so if your kit does not have one, get yourself a good quality Servo Saver. I would also recommend you replace the soft steel Turnbuckles, Tie Rods and pivot/steering shafts with Titanium versions and if you get serious about your racing, lightweight Titanium Drive shafts, dog bones and CVD (Constant Velocity Drives). The standard steel ones bend far too easily.

   Gears in RC model cars often cause problems. Head on collision accidents can damage gear teeth on Nylon/Plastic Spur Gears and sometimes even the Bevel Gears inside the Gearbox. Hard impacts may also slacken the nuts and self taping screws that fix the Motor in Position, making it possible for the Pinion Gear to pull out of mesh a little and damage the teeth on your Spur Gear. To try and prevent this, you should always fit locking (Nyloc) nuts and if your mount uses self tapping screws, change the plastic motor mount occasionally to ensure a tight fit.

   Plastic Ball Connectors can cause problems. For top level Radio Controlled model car racing, they need to be checked for tightness and if considered necessary changed after every race meeting. Something like a loose fitting connector popping off could easily lose you the race, so always err on the side of caution.

   Quite a number of New car kits come with Plastic and Sintered Brass Ring type bearings. These can cause problems if at some time in the future you want to fit a full set of ball bearings so I recommend you discard the brass and plastic types before installation and get yourself a Hop-up set of Shielded Steel Ball Bearings.

   Finally, try to keep the Centre of Gravity of your model as low as you can. This can vastly improve the handling of your car when cornering at high speed. For On Road Drift/Touring cars the Ride Height should be around 5mm, for Buggys, Trucks, Truggys and Monster Trucks, as low as practical for the track conditions. Body Roll can be reduced by using Stabilizers, Anti roll or Sway Bars. Tuning Springs may also help with thicker, or thicker Silicon Oil in the Shock Absorbers. Also look towards mounting the Transponder as low as you can in the Chassis.

Hints and Tips

Keeping Notes

   If all you will ever do is go racing at your local track every week, then this article is not for you. However, if you ever look towards travelling around to different tracks around the country, or even the world, the value of keeping notes is all too obvious.

   Every time I raced in a regional or national competition meeting, I would make detailed notes, aided by a little local knowledge initially and later fine tuned to suit my own driving style.

   My experience now means there are few, if any outdoor tarmac tracks within a 300 mile radius I haven been to and my notes on motor, gearing, camber angles, shock settings, tire choice and what inserts work best for that particular track, amongst others, allow me to save valuable time on the finer points of car setup, that can be done in the warmth of my own home on the kitchen table days before the meeting, instead of the often crippling heat, or the arduous conditions inside a wind blown tent.

   There are lots of methods for making notes on setup. The easiest perhaps is to download the blank pages often supplied by your cars manufacturer with a line drawing of your car and spaces for you to fill in as to the setting you prefer. Great if each time you go to a particular track the conditions are always constant. Notes made on a cold windy day will be little use on a hot sunny days racing on the same track.

   Manufacturers setup pages for their top drivers can also be useful as a starting point, but you should never take that setup as being the best there could ever be.

   So, the first note you should make is of the weather conditions. The wind and its direction isn't really what I am talking about, although it can have an effect on your cars handling, it is not something you can change your setup to handle. Track temperature and humidity are the main things to note. Not the average for the day, but for each round of racing. And note what tires you used and how the car handled in each race. Detail everything that might be useful in the future, no matter how trivial.

   Note the motor used and the gearing. Check the temperature of the motor after the race, how much charge is left in the batteries. You may have won the race, but there is always room for improvement … your competitors will be doing just that.

   Every bit of information you compile will be useful for the next time you visit that particular venue. Weather forecasts these days are far more accurate than they used to be, so the adage "fore warned is fore armed" fits the bill. Simply search through your notes and find a day you raced with similar conditions to those forecast and set up your car to suit. But don't stop there.

   The conditions may be the same as they were when you made your notes, but that doesn't mean you can't improve your setup. Your practice laps will soon prove if your previous setup was correct, or give you a basis for more fine tuning.

   If you want to be the best, you have to work at it. Success doesn't come easy. You can be the best driver around, but if your setup isn't perfect you will never step up onto the winners rostrum. My motto … if you never try anything, you never do anything. And if you never do anything wrong, you aren't trying hard enough.
