Default X-ray, Hudy, and Serpent - help me clear something up

A few years ago (2004) I was under the impression the these 3 companies were the same. I guess the misconception arrived at the fact the xray would use spring steel turnbuckles and other parts, while Hudy would make matching spring steel tools. Also Serpent would use if remember correctly the same material?

I noticed now however that xray no longer uses ST turnbuckles and has gone to alum? - how come?

however serpent is using ST in their newest offering. If I wanted to source ST hardware, which company should I turn to now (2011). I the past I would look at X-ray.

Thanks.

There is a man, Juraj Hudy. He is an engineer. He was into RC and designed his own cars for himself. He is a great engineer and founded the company called HUDY which specifically worked with metals and made parts for slot cars and RC cars, and of course, the legendary tools. They then became an OEM partner for Serpent for a while along with Corally, which meant they made a lot of the metal parts for Serpent and Corally cars. After a while, Juraj decided he wanted to go and make his own car on a larger production run - XRAY.

Here's a more detailed rundown from the XRAY website.

A brief history of Dipl. Eng. Hudy Juraj and his contribution to the RC world:

1972/74 - first self-designed and manufactured slotcars. Juraj became Multi-Champion of Middle and Eastern Europe in slotcar racing. These slotcars were No. 1 at that time and were winning all the races.

1975 - the first RC cars were designed and produced; the focus was on nitro and electric cars. All of the cars were handmade in small series in a workshop 9m2. At the same time, the first handmade bodies were produced from laminate and epoxy material.

1977 - Juraj produces hand-made chassis plates from 4mm thick duraluminum. The car in the picture, called SHADOW, uses this kind of chassis.

1978 - a new RC car was designed with the motor in a vertical position. The car featured solid suspension and a flexible chassis.

1979 - Juraj designed a new nitro car with the motor in a horizontal position. The car featured solid rear suspension and a front suspension using simple dampening.

1980 - a newly-designed nitro car featured a differential in the wheel. The front of the chassis was made from fibreglass, and the rear from duraluminum.

1981 - a new nitro car featured solid suspension, a central differential, adjustable width and caster, and simple dampening. The first bodies were produced using a vacuum machine and special ABS material. From this year onwards, 10-15 cars were hand-made each year.

1982 - a new nitro car featured independent suspension, rear differential, and direct drive through gears between motor and rear transmission. A front central shock is used, and a wing is attached directly to the rear suspension.

1983 - a new nitro car was produced, based on the successful 1982 design. New centrally-mounted front shocks and an anti-roll bar were introduced, and a Serpent fueltank was used. This ultra-stiff chassis design was the most professional, and achieved the greatest racing performance at the time.

1984/85 - one of the world's first 4WD nitro cars was introduced, using driveshafts and a front one-way differential.

1986/87 - a new nitro car featured an automatic 2-speed transmission, and fully-enclosed front and rear transmissions to provide dust protection. This car was great for dusty racing conditions.

1988/89 - the first off-road car is designed and manufactured. An improved nitro car also appeared, based on the successful 1987 design, and also featured ultra lightweight materials. These cars featured a purely technical design that distinguished them from "toy" cars. There were no unnecessary parts, and everything was strategically placed for best weight distribution and performance.

1989 - After the fall of communism in Eastern Europe, Juraj establishes his first company, named SPECIAL, which was later renamed to HUDY. Juraj moves manufacturing from his own flat/workshop to a garage 60m2. The first machines are bought and real production begins. The company focuses on designing accessories and tools for slotcars. The first comm lathes and slotcar tire truers are designed. The HUDY company has 60 employees at this time, over 2000m2 production factory, and manufactures the highest quality RC products that are sent to over 30 distributors around the world.

1990 - Juraj introduces his products at SERPENT headquarters in Holland, and HUDY company becomes the manufacturer of special transmission parts using special spring steel. To this day, HUDY uses their top secret, self-developed formula to produce the highest quality parts from special spring steel. The co-operation with SERPENT continues, with HUDY producing spring steel parts as well as parts from duraluminum (chassis), and graphite composite materials. HUDY continues to use their extensive experience and self-developed technologies to design and manufacture the highest-quality parts.

2000 - Juraj establishes the XRAY MODEL RACING CARS company, which focuses its many years of design and manufacturing experience to produce high-tech, high-quality RC model racing cars. The first project, named "T1", is designed and introduced.

2001 - XRAY products are represented and distributed in over 30 countries around the world, supported by professional services and a factory team. TEAM XRAY is established, made up of dozens of top professional RC drivers around the world who look forward to get maximum results during their race seasons.

So basically, HUDY and XRAY are owned by the same man, but Serpent are not connected other than being an Original Equipment Manufacturer in the past.

Xray products are all designed/made in Slovakia. Serpent, with a design/management presence in the Netherlands (plus some design in the US), has all its products made in China.

The T3 2012 comes with spring steel driveshafts up front for durability, aluminum in the rear to lighten the drivetrain.

The turnbuckles are aluminum, but are thicker, I think. I know they use a 4mm wrench instead of 3mm with the steel ones.

ok so then I wonder if Xray will stop making spring steel turnbuckles....
and IF I need some then I need to look at T2/T1 parts. (I realize the T1 is a very old car already)

Probably, since EFRA and ROAR lowered the minimum weight to 1380 grams. I still had to add 44 grams to meet the minimum.

The original S411 kit does use spring steel turnbuckles like you said but the new LE S411 does use orange aluminum tb, and I am sure its because of the weight savings and also because the car was anodized orange as well.

I still perfer the spring steel stuff when you are racing the car on a club level as the extra strength and durability is very welcome to me, but when racing the nationals or other big races the aluminum would reduce a small amount of weight.

^ agreed. I noticed on the serpent site they have both models. However Xray doesn't make SP turnbukles for the T3.

The T2 (including 007, 008, & 009 models) Spring Steel Turn buckles are listed as option parts for all T3s and visa versa. The Orange anodized T6 Aluminum turnbuckles are listed as option parts for all T2s and T3s. They went to the Swiss 7075 T6 aluminum turn buckles on the T3s because they are half the weight of the spring steel turnbuckles. Great for top level drivers but not so good for us mere mortals that pop the occasional board on race day (or in my case, several boards a race day )

Go to the Xray website and download the T1 & T2 & T3 Parts Cross Reference Table. It is available as both a .pdf and a MS Excel spreadsheet. It shows what parts were originally available on which car and what parts will interchange. Basically all T2 & T3 suspension parts and some other parts will interchange. They may be slightly different lengths, have different shock mounting hole positions, different sway bar mount positions, and/or be made of different materials (different hardness of plastic for different applications i.e. Foam spec cars had harder plastic suspension parts and thicker chassis) but all T2 and T3 model suspension parts will physically bolt to any version of a T2 or T3. You may have to swap them in pairs to keep suspension symmetry side to side so it handles properly but they bolt up. Not sure about sway bars and the steering systems are different between the T2s and T3s but basic suspension swaps. HTH
