XRAY MODEL RACING CARS was established in the year 2000 by Dipl. Eng. Hudy Juraj.Even though the company is brand new, the founder has had long and successful experiences indesigning RC model racing cars.

Our top 3D CAD designer guru working at aspecial workstation. All of Jurajs ideas wereput into leading-edge 3D contructionsoftware, the result of which was the firstvirtual prototype. From the first prototypedesign, we tweaked various parameters tocreate totally different virtual prototypes.

Software analysis of arm movements. Wespent a lot of time to find the optimalchassis-roll points. The final design uses the

optimal chassis-roll point on the adjustableball. The main intent while designing thearms was not only to make them crash-resistant, but also to have them as long aspossible, and to locate the arc-moment asclose to the car's centerline as possible toachieve maximum stability.

Software analysis of drivetrain performance,and looking for the best drive ratios. Wetested several different drivetrain design

layouts, and some with different rotatingmasses. Because the layshaft is the only partplaced above the center-of-gravity, it has tobe hollow to be as light as possible, andwhen combined with the press-fit adaptor, itmust be vibration-free.

Externally adjustable ball differential withspecial Labryrinth Dust Covers. The focus wasto get maximum transmission of rotatingmoment with minimal weight. Thedifferential is designed to require minimalservice, due to the protection afforded by theLabyrinth Dust Covers. After the prototypedifferential was made, we tested manydifferent washers and trust bearings toachieve maximum performance and long life.

The final prototype design accomplished in3D virtual reality. The chassis design wasexposed to many virtual tests after whichproduction on the f irst prototypes started.

Software analysis of the stress characteristicsof plastic parts. The 3D construction softwarealso enables us to check the design of theparts and how they absorb different impacts.

The design of the chassis was accomplished in the middl1999, and several differently designed prototypes werechosen for production. All of the prototype parts werecompletely produced in-house using CNC milling machinthat were connected directly to the computer using the 3software. First to be manufactured were the chassis, whiused graphite material and duraluminum bulkheads. All future plastic parts were milled from nylon composites. Mof the nylon parts were made on CNC milling machines.

At the end of 1999, the first prototypes were complete. Rworld tests began on asphalt and carpet tracks. Whiletesting the prototypes, minor details were corrected andseveral parts were changed. The focus was on testing althe adjustment possibilities and how they effected the caand if there were any need to provide more adjustmentpossibilities. After the minor details were rectified, the pawere again produced and changed on prototypes and lo

term tests began.

After several months of testing, the final chassis design wchosen. To make sure that the final design was really thebest choice, a new prototype was again made from grouup. The prototype was not run in secret, but in official raThe ensuing victories confirmed that the design andperformance of the car were the best.

The reason that Dipl. Eng. Juraj Hudy decided to startproducing model racing cars again after such a longabsence, is his intention to set a higher quality standard inthe RC model car market. Based on long and very successfulexperiences with designing and producing his own RC nitroand electric cars, and also on his experiences with producingspecial parts for SERPENT cars, Juraj decided to start toproduce his own model cars again.XRAY's first project was to create the ultimate, true racecarfor the highly-competitive electric touring car class.

The design of the chassis was started early 1999. The designwas made from the ground up in virtual reality using special3D construction and analysis software. For a long time,many different designs were devel oped in the computer, andtests of these cars were done in virtual reality. The smartsoftware enables us to check the durability of the parts by

virtual crashes, and enables us to check the flexibility of thechassis by inflicting virtual impacts to the chassis. All plasticparts were tested for stress and impact characteristics. Thesoftware checks the optimal positioning of all parts on thechassis to achieve the lowest center-of-gravity and bestweight distribution on the car.

The key design features that drovethe development of the T1 were:s reduced dimensions of rotating componentss minimized rotational resistance for all componentss maximized drive train performances dramatically reduced chance of breakage of transmission

components (therefore the design without using belt-tensioner)

s lowest possible weight of all non-dampened componentss lowest possible center-of-gravitys longest possible suspension arms, positioned as close to

centerline of chassis as possible in order to achieve thehighest stability

s maximized number of adjustment possibilities to adapt thecar to any condition

s increased chassis stiffness to protect again the effects ofcrashes

s design of the chassis in the way that it does not changethe set-up and driving characteristics after a crash (noneed to trim the car)

s very easy and fast services pure high-tech designs best racing performance in different racing conditionss the best quality materials used for production

These images show the differences between theprototypes produced from nylon (left), and the finalproduction parts from the finished moulds (right).Take note of the differences between the prototypeand final production of the rear upright; the uprightwas dramatically compressed to have minimizedrotating parts (wheelaxles and ball-bearings) as wellas to have minimum weight of the plastic part itself.

Before producing the moulds, we had toproduce all the electrodes. All electrodes wereproduced in-house to ensure maximumquality. The photo shows an already-usedelectrode of an arm.

Creating a mould. We use the highest-qualitySwiss CNC moulding machine.

A production mould for arms.

The first half of the arm mould is completed.All parts of the arm that are hollowed needto be inserted into the mould withpneumatic-operated pins.

A complete arm mould. It takesapproximately 150-400 hours to produceone mould. For the complete T1 there were20 moulds produced.

Software analysis of injecting the plasticmaterial into the mould. The software checkswhen and where the material meets, and if itcreates any air bubbles inside the plasticpart. Air bubbles in the parts would cause thepart to break easily.Our engineering experiences eliminated allpossible flaws in the moulds, making ourmoulds the highest possible quality and ofthe perfect engineering concept.

The transmission is very important to get maxout of the car. We couldn't compromise by usor an inferior design. HUDY company, a renowof special spring steel parts for SERPENT modcontracted to produce all the transmission paspring steel.

SPECIAL PA

As the production parts were being made, the prototypeparts were replaced on the test chassis. This involvedassembling and disassembling the car hundreds of time

HUDY company, renowned for producing the highest quRC products and manufacturing special parts for SERPENmodel racecars, was contracted to produce all of thetransmission parts from special spring steel. HUDY uses own proprietary manufacturing techniques to produce thhighest quality parts from special spring steel. This mateallows to produce lightweight parts without compromisintheir strength. This allowed to make the tiniest drive shathe world, which the T1 features.

At the end of 2000, all of the parts were completed andcar went through numerous road tests using the parts th

are included in the standard kits. Initial quick laps confirour expectations, and we were happy that the car was qstraight off. Every single change in the setup wasimmediately reflected in a change of a driving characterThis fulfilled our main intention - to produce a professioracecar that you can adjust for any condition.

In May 2000, the production of the first moulds began. Allmoulds were produced in-house, and the injected parts wererigorously tested. If a part coming out of the mould was notperfect, the mould was modified. All moulds were designedin the Pro/Engineer 3D software, which enables us to makethe best mould designs with respect to the injection process.The software simulates the injection of the material into themoulds, and shows the weak points of the mould; the resultof which can be a part that can be very easily broken,something that is not acceptable to us. Using our extensiveengineering experience, we design the moulds such that theinjected material flows perfectly into the mould andeliminates any potential weak points in the finished part.

Our plastics engineering experience ensures that all of themoulded parts have a perfect fit. All of our plastics' flow,shrinkage, and deformation characteristics are taken intoaccount when designing parts that won't require any hand

fitting. For example, the arms have holes that line up perfectlyand assemble with the best precision. You can slide the pivotpin through both holes without modifying the arm, or makingthe holes larger. We are proud that we are one of the veryfew companies that pays attention to such small details thatmake perfect parts.
