1:8 GT-luokan uutuus vuodelle 2017
The GTX8 is an all-new 1/8 luxury nitro GT car based on the XRAY’s European Championship-winning XB8 off-road car. Sharing many high-performance parts the GTX8 incorporates all the finest details to achieve a state of perfection.
The GTX8 is typically XRAY–premium, professional, high competition R/C car for the most demanding racers, developed with attention to the smallest details and backed by premium service & support…a luxury masterpiece.
With XRAY's uncompromising design philosophy bringing everything together to make the best GT nitro car, the GTX8 has the unique XRAY character, born of precision craftsmanship, highest attention to detail, and using only the finest quality materials.
Made in Europe.
Designed, developed, and fully manufactured in-house at the XRAY factory in Slovakia, Europe, using the most high-tech German & Swiss machines and premium European materials, crafted with XRAY's legendary attention to detail by our artistic production specialists. The GTX8 is truly a masterpiece.
The chassis is CNC-machined from 3mm high-quality Swiss 7075 T6 aluminum, strategically machined in low-stress areas, and then anodized to make it as light as possible without affecting strength or rigidity.Non-essential material below the engine, fuel tank, and differential was removed to allow for the lowest possible center of gravity and appropriate chassis flex.
Front and rear chassis braces have significant influence on chassis stiffness and flex, and as such have a great impact on handling under different grip conditions.The longer rear brace is moulded from a medium-stiff composite mixture for proper flex & rigidity, and allows the mounting of optional graphite inserts to reinforce the brace to make it even stiffer (suitable for high-traction conditions).
Diff bulkheads are an important chassis component, housing both the front and rear differentials and providing mounting points for the suspension mounts and shock towers.The diff bulkheads have been designed for extreme durability, while providing easy access for tuning and maintenance.
Pivot Ball Suspension.
XRAY Pivot Ball Suspension XPBS™ is a uniquely innovative concept, and smart R&D design. The ultra-robust pivot ball suspension has integrated suspension geometry adjustment, with different kingpin plates being optionally available.
The complete integrated suspension geometry adjustment includes:
• Track Width
• Bump Steer
• Upper Roll Center
• Lower Roll Center
• Kingpin angle
Correct suspension geometry is one of the most important features of any RC model car, while at the same time being one of the most difficult & challenging features to design properly.
Suspension is always a mixture of:
• Design & shape of individual suspension parts
• Flex & hardness
• Mounting system
• Geometry & position of mounting points of connecting parts
From the suspension arms, through the suspension blocks, to the robust steering blocks, every suspension part has been carefully designed for the 1/8 racing platform to provide responsive racing characteristics in all conditions.
I.S.S.™ Suspension Holders.
The aluminum suspension holders feature Integrated Suspension Settings™ (I.S.S.) which allow for quick & easy suspension geometry setting.Using eccentric suspension bushings inserted into aluminum suspension holders – as well as additional suspension shims – the GTX8 suspension geometry can be completely adjusted in mere seconds.
XPBS™ steering blocks are unique, innovative, smart... an authentic XRAY innovation.
The steering blocks feature the following integrated geometry adjustments:
• bump steer
• kingpin angle
The steering block consists of a super-lightweight composite steering block and stiff Swiss 7075 T6 kingpin plate. The steering block is mounted via massive pivot balls into the upper & lower arms.
The upper pivot ball is mounted into an adjustable upper ball joint and via roll center shims to the kingpin plate; this assembly allows camber and upper roll center adjustment. Using shims of various thicknesses, the upper roll center can be adjusted quickly & easily.
The lower pivot ball is mounted into the steering block via an adjustable alu nut and composite bushing. By adjusting the pivot ball, both track-width and camber can be adjusted.
• A higher roll center (more shims) is recommended for grippy, high-traction tracks as well as for bumpy tracks.
• A lower roll center (fewer shims) is recommended for slippery and smooth tracks.
The included kingpin plate has two different mounting possibilities to choose either 0° or 7°.
The ultra-tiny XPBS™ rear uprights are unique, innovative, and smart… an authentic XRAY innovation.The rear upright consists of a super-lightweight composite upright block and stiff Swiss 7075 T6 mounting plate.
The upper roll center plate has a unique design that allows easy changing of roll center position. The roll center plate features 2 roll center positions; by reversing the orientation of the plate another 2 roll center positions are available. The roll center shifting is in range of 2.5mm. The roll center height of the upper camber link can be adjusted via shims of various thicknesses. The composite upright features 2 lower roll center positions.
The outer suspension pin – on which the rear upright sits – features 2 shims which allow for additional wheelbase adjustment.
The uprights feature integrated geometry adjustments including:
• upper roll center
• lower roll center
The GTX8 has a conventional shaft-drive 4WD drivetrain featuring:
• Front & rear gear differentials with adjustable oil viscosity,
46T crown gears, and 14T pinion gears
• Central 2-speed gearbox. (1st) 49T/16T, (2nd) 46T/19T
• Front, rear, and central CVD drive shafts
