The TRF component systems of Tamiya are in 1:10 - electrical smooth course route car classes already for years very successfully. After the TRF 414 Tech Racing developed the TRF 415, which is world-wide in almost all running series very successful together with the Tamiya Racing Factory. On 30 October 2004 Marc Rhine pool of broadcasting corporations in Kissimee/Florida with the first evolution stage of the TRF 415, that became 415 ms at first attempt world champion. A worthy cause to regard and test on heart and kidneys the chassis once in the detail.

The component system
The 60 times 30 centimeters large box is printed on with a body in the Marc Rheinhard Design and a picture of the broadly grinsenden Marc Rhine hard. Besides one finds still the reference the fact that it concerns the world champion chassis here and only into limited edition is to be had this. Contents of the box present themselves, as with competition models usual, as pure kit. In a stout filled bag smaller bags are after building groups sort all small articles contained. Among them the chassis and the building guidance are in the used Tamiya format. To mention it is that neither electronics, still another a body or tire are attached to the component system.

The chassis
The structure of the TRF 415 ms does not bring much new. An extraordinarily torsionally stiff carbon double cover construction with 2.5 millimeters strong chassis and two millimeters a strong upper deck form the basis. One finds the reaming for the Akkupack on the right side. Engine, servo, automatic controllers and receivers are arranged on the left side. Are in front and in the back wishbones graphite-strengthened down, with which at the front two and at the rear side three points for the shock absorbers are bored in each case. By simply turning of the wishbones one can select thus between five different points. Into the wishbones three-millimeter grubscrews are screwed in, with which the suspension rebound movement can be limited. As upper wishbones are used right left-hand thread seaweeds with ball cups. Over these the fall can be adjusted later. For the rear axle wheel carriers with a degree of toe-in are attached to the component system. These are bolted by means of three-millimeter metal pin with set thread mobile with the wishbones. For the adjustment of the height of the roll center at the rear axle the chassiseitigen fastening spots of the upper tie rods can be adapted by supporting shims under the fastening spot on the aluminum Bulkheads to the respective distances and grasp characteristic.

At the front axle one continues to trust in the proven C-stroke-system. This C-stroke are attached to the component system in the wake variants two degrees and four degrees. First the branch wheel carriers were blocked. Of course be adjusted with the TRF also the toe-in at the rear axle can 415 ms. For this purpose differently broad hanging up attachments for the lower wishbones are attached to the component system. Thus toe-in toe-out of zero can be adjusted degree up to two degrees.

Since the wishbones are narrower about five millimeters than the distances between their photographs, spacers must be pushed onto the axes of rotation. By the arrangement of the cases before or behind the wishbones, the wheel base can be extended and/or shortened by in each case six millimeters with 415 ms. Particularly to mention also the Tamiya absorbers, which do not represent anything unusual after the usual concept with aluminum housing, absorber piston with two holes and O-ring piston rod sealing, are however in function not to strike tightness and effect way are. The absorbers rest by means of lower ball photographs directly on the wishbones, whereby they hold on above to carbon absorber bridges with in front four and in the back five points. Helpfully with the tuning of the vehicle are also the front and rear stabilizers, which are attached to the component system in in each case three different hardnesses.

Also the propulsion principle is a proof of worth: The engine propels the medium wave over a 64-dp-Feinverzahnung, over which with two belts the rear Differential and the front free-wheel are then moved. From here drive shafts from aluminum at the wheels provide for movement. The ms is equipped contrary to its predecessor thereby with the white light run belts, which continue to improve the anyway already low-friction drive still. The fact that all mobile parts are completely running in ball bearings does not have to be mentioned with a competition model probably more separately.

Attention exciting presents itself also the steering element. With altogether six ball bearings it is unbelievably low-friction and precise. Over tie rods with right left-hand thread the toe-in can be adjusted. In excellent Fertigungsqualität one finds also the blue anodized aluminum parts. The new Motorträger is attached to the ms now also in series, which provides for a better cooling of gestressten engines.

Assembly
Over the quality of the building guidance still further praising words do not have to be lost. The description of the sections is excellent, so that the assembly is to be created also for an untrained model construction amateur in to two evenings. Praising to mention is here also the quality of the parts. There is not necessary up to removing the usual injection moulding remainders at the plastic parts and rounding the sharp Cjhassiskanten off by means of Dremel and Schlüsselfeilen reworks. One should dedicate however little time to sharpening and following sealing of the chassis and all other carbon parts with second adhesive. The edges of the milled parts are naturally quite sharp edged. Apart from the danger of injury one reduces also the risk that the carbon layers separate with more intensive enemy contact from each other and the expensive parts are destroyed in such a way. The reaming for the Akkus should be chamfered from above with a file so far, which the Akkus at the lower surface locks concisely with the chassis. This provides on the one hand for a better seat of the cells and lowers on the other hand the vehicle emphasis. The register accuracy of all parts is excellent, so that for example the wishbones move extremely low-friction and free from play in their carriers.

The TRF was completely installed after a long evening. After the remote control was inserted, it applied to apply now still another according to rank lacquer finish on the Protoform-Mazda-6-Karosserie, before it could go to the first test.

TRACK test
Equipped with the short Futaba-9550-Servo, a Hara Twister2-Regler, a Peak-Vantage-12x2-Surikarn-Edition-Motor, a Peak-PowerFlo-SP2-Akku and Sorex-28-Reifen was then to the first Rollout on the Trainigsstrecke of the SLR Ingolstadt. As Setup first zero degree and in the back a degree toe-in were selected in front, the fall was stopped to in front one degree and in the back two degrees. The absorbers received a filling with 60-WT-Orion-Öl. The choice of the feathers/springs fell in front on the white, in the back on the blue Tuning feathers/springs of Tamiya. As points of hanging up for the absorbers the position came from the building guidance to carrying. In addition at the front axle the yellow and thus centralhard stabilizer was used, in the back first without it did.

The first rounds applied to give over on it gas for the first time correctly to adjusting straight line discharge and guidance excursion. The 415 ms had with the selected Setup very much „a loose “tail. Thus again into the box. At the rear axle two degrees of toe-in were stopped, which installed absorbers of the front axle a position flatter fastened. With this attitude then better round times could be driven as with „old “415er at first attempt. The vehicle could be steered with unbelievable precision around the course. The handling is neutral and at any time controllable. In the further process still some changes in the chassis were made. „The world champion “let each change feel, without reacting thereby exaggerated.

Next a test stood on the permanent resounding distance in tubing brook on the program.

The distance consists of Nadelfilz and distance delimitations of wood. There the layout of the course for a 1:10 - gate car is too closely held, needs the 415 ms much steering element. Therefore the absorbers got again a steeper angle and the front Stabi moved into the spare part crate. The car could be steered despite the self-willed routing with breath-robbing precision around the course. A small inspection after the tests did not point any damages at the vehicle to my astonishment. A complete disassembly of the chassis after the intensive tests should show, how it stands around the wear of the TRF 415 ms. However no excessive manifestations of wear could be determined. Only the Differenzial and the absorbers should be examined regularly.

Really world masterfully?
The policy of the company Tamiya stands out in the frequency, in which new models are brought on the market, clearly against the competition. With the model designation TRF 415 ms one expects first „only “an evolution stage of the TRF 415. With the exact Hinsehen one recognizes however a completely new wheel suspension, which was taken over as far as possible by the Tamiya TB Evo 4. Also the propulsion principle was consistently developed further with the new, white light run belts. The target group of the TRF 415 ms is reliably the ambitionierte competition driver. Countless successes and above all the world champion title prove this. By an excellent Baukastensetup and the easy, uncritical controllableness of the vehicle is the kit however also for competition A RISERs and hobby driver a genuine alternative. Only the quite high price deters during the purchase decision.
