Tamiya Team Hahn Racing MAN TGS - #58632 (Radio Controlled Model Review)

1/14 Scale Electric Tractor Truck - TT-01E Chassis:

  Released by Tamiya on July 16, 2016 and based on the TT-01 Type-E chassis, this kit is of the Team Hahn Racing MAN TGS Racing Truck, that took part in the 2015 European Truck Racing Championship, driven by Joachim Hahn.

  The Lexan body shell in this kit is an accurately realistic representation of the original. An ESC is provided but needs battery, charger and Radio equipment to complete.

  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.

  Plastic and sintered brass bush type bearings come as standard with this model, 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 Team Hahn Racing MAN TGS
Tractor Truck (and What to look for)


   Buying a used Tamiya Team Hahn Racing MAN TGS Electric Tractor 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 Tamiya website, or purchased separately on eBay. With an instruction manual, any problems with your model Tractor Truck you may discover can easily be fixed.

Dampers
   When you receive your used Tamiya Tractor 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 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 Team Hahn Racing MAN TGS 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 Team Hahn Racing MAN TGS 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 Team Hahn Racing MAN TGS Tractor Truck 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 Tractor 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 Tractor 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 Tractor 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 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 Tractor 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 Team Hahn Racing MAN TGS 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 Team Hahn Racing MAN TGS 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 Tractor 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 Team Hahn Racing MAN TGS model and good racing.

Hints and Tips

Toe Angle

   When you first build your RC model car, you will no doubt have made all the settings advised in the manufacturers' manual and will take it out on the back yard not thinking of things like camber, caster or toe-in … I know I did. It's only when you get competitive that you start learning about these things and just what a big difference they can make to the handling of your car. One of the more effective of these adjustments is Toe-in.

   The term, toe-in, toe-out, or toe-angle, refers to the alignment of the front or rear wheels, when viewed from above. Front toe-angle is easily adjusted via the track rods or turnbuckles that link to the steering mechanism or directly to the steering servo horn. At the rear, some models like the Schumacher Mi1 can be adjusted by turnbuckles, but most models, on and off-road, have a set of hub carriers to provide the desired toe angle.

   Front toe-in reduces steering when entering a corner, but improves steering response on corner exit under acceleration. On the straights, toe-in will also improve the cars stability while accelerating.

   Front toe-out will improve steering on corner entry, but makes the car unstable under acceleration on the straights and on bumpy tracks. The usual recommendation is to have up to 1 degree of either toe-in or toe out.

   Rear toe-in is generally found as the standard setting on most on-road and off-road RC models.

   More rear toe-in provides the car with more power under-steer, as well as improved stability and rear end traction. This setting is recommended for low grip tracks.

   Less rear toe-in slightly reduces steering on corner entry, but improved steering under acceleration.

   To measure toe-angle, I used to use my trusty vernier callipers to measure the width at the front of the wheels and the rear of the wheels and using this information along with the diameter of the wheels simply calculate the angle. Or, you could alternatively use this data to draw a triangle on a sheet of paper and measure the angle with your trusty school protractor.

Rechargeable Batteries
for RC Models


   At the time this article was written, there are four types of Rechargeable Batteries that are commonly in use of Radio Controlled Models.
Ni-Cad (Nickel Cadmium) Batteries have been around the longest. My first stick battery, purchased way back in 1987 was rated at 1200Mah (Mili Amp Hours) and with a silver can 27 Turn motor my Tamiya Boomerang would run around in the back yard for a good seven minutes before slowly coming to a stop. Ni-Cad development continued until around 1998 to a maximum rating of around 2000Mah and matchers pack builders and battery technicians were able to put together six cell packs with voltages approaching 7.4 Volts, to give those that could afford them, an edge over the rest.

   Ni-Mh (Nickel Metal Hydride) Batteries came along in the late 1990s and by the year 2000 were available at ratings up to 3000Mah. Again, matchers and pack builders worked hard to provide the ardent racer with packs to provide that little bit of extra power and ESC manufacturers also chipped in with improved controllers to take full advantage of this new technology.
   Now the problem wasn't gearing the car to get to the end of the race using the available battery power, but to find the brushed motor that could handle gear setting that provided the speed and acceleration without the motor overheating and wearing the commutator too much so it needed a skim after every 2 runs. My favourite at that time was the 9 Double.

   More recently, Li-Po (Lithium-Polymer) Batteries have appeared on the scene, providing are a huge step forward in performance when compared with Ni-Cad and Ni-Mh batteries. However, Li-Po Batteries are much more expensive than previous battery types, have a shorter effective life of between 200 and 400 charge cycles, compared to well over 1000 charge cycles for Ni-Cad and Ni-Mh and a high degree of care has to be taken when charging Li-Po batteries. They have been known to burst into flames or even explode, for this reason I do not recommend Li-Po batteries for RC beginners.
   Another problem with Li-Po packs is they are physically bigger in size, so for those with older "Vintage" models, they may not fit into the provided space for the battery on the chassis.

   The latest development in battery technology for RC are Li-Ion. Originally produced for Laptops, Ipods, Tablets and the like, they are now available for RC models. Much like Li-Po for price and charge cycle life, the power and capacity is a moderate improvement, but for me, at the moment, not worth the expense.

   One final word of warning. NEVER leave your charging Li-Po or Li-Ion battery unattended when being charged and NEVER above the recommended charge rate. After use, store each battery with about 60% charge remaining and always in a fireproof bag.
