2014 All-new Features
- New chassis
- New radio plate
- New fuel tank mounting system
- New center body mount
- New smaller 2-speed
- New front middle shaft mounting system
- New shock towers
- New shocks
- New battery holder
The NT1 chassis has been redesigned to achieve better steering characteristics.
The front of the chassis was widened to make the car less twitchy and easier to
drive. The new front middle shaft holder is positioned differently on the chassis,
and there are new holes for a new battery mounting system.
The chassis has been designed to enhance performance in the corners. Overall, the chassis is very narrow to increase chassis flex and thus to generate more traction and steering. The narrow chassis also minimizes the contact with the track in corners and will eliminate the feel of the car ‘stopping‘ mid corner.
The lightweight chassis is CNC-machinedfrom premium Swiss 7075 T6 aluminum and is strategically machined in low-stress areas to make it as light as possible without adversely affecting strength or rigidity. The area below the engine is machined so the engine sits lower to reduce the CG when using the optional engine mount and flywheel. The area under the engine also features air-flow cut-outs to allow extra airflow to cool the engine. The outer edges of the chassis have been beveled and screw holes have been countersunk in order to provide a smooth lower surface. Provisions have been made to accommodate graphite reinforcing inserts or additional balancing weights, front and rear to tune chassis stiffness, balance, and CG.
The radio plate was redesigned to allow mounting of the new center body mount, and there is more space around the fuel tank to allow more movement.
The radio plate is part of the Multi-Flex™ setting and allows for very quick & easy flex adjustment. Bushings on the back of the radio plate allow it to be attached to the mounts either rigidly fixed or with an allowance for flex.
The ‘rigidly fixed’ setting is recommended for high traction conditions.
The ‘flex’ setting is recommended for low-traction tracks to generate more traction.
The muffler mounting system was redesigned as well. The muffler mounting is not attached to the radio plate any more, which eliminates the negative influence of flex. Now the radio plate flexes more equally to both sides which improves consistency and, as it allows more flex in the front, also provides for more in-corner steering.
Fuel Tank Mounting.
The fuel tank mounting on the radio plate has been redesigned to use a grommet and new O-ring with special screw. With extra space around the fuel tank in the radio plate, as well as the new mounting system, the fuel tank has greater movement in all directions which improves fuel pickup and scavenging as fuel is used up.
The 75cc fuel tank with hypertonic tank lid and internal stone-type filter is positioned in the center of the car, and features a unique low-profile design to allow the fuel tank to sit as low as possible. The fuel tank is mounted with rubber grommets to reduce vibration.
The fuel tank is molded from a special composite mixture which guarantees it to be extremely strong and robust. The fuel tank is glued together using a special self-developed robotic system that ensures maximum accuracy and precision in pre-heating and gluing.
The receiver battery pack is located beneath the fuel tank to help create a low CG. Using the optional micro-size receiver battery pack allows the fuel tank to be lowered by another 3mm, creating an ultra-low nitro touring platform.
Center Body Mount.
The radio plate now has an extra hole to allow the mounting of the center body mount which protects the body from deformation while refueling and also increases car stability in high speed corners.
The new smaller 2-speed gearbox has been lightened for improved bottom-end power and acceleration. Both the adapter and carrier for the 2-speed are now smaller and lighter to reduce the rotational mass in strategic areas.
Front Middle Shaft Holder.
The aluminum front middle shaft holder was redesigned for easier access to the front belt and pulley for easier maintenance. The smart design also allows for quick & easy front belt changes. The muffler mount is also incorporated into the new holder.
Both front & rear shock towers have been made higher to fit new front & rear shocks.
Machined from premium-grade 3.0mm graphite, the shock towers are small & light.
The shocks are completely redesigned for improved traction and steering characteristics, and optimized up & down travel. The redesigned longer shock bodies accommodate the longer shock shafts, and new pistons made from special white Delrin™ material have been optimized for hole number and sizes.
Shock rods have been specifically hardened to ensure long life and maximum strength
The set of pistons include 2 and 3-hole pistons with 1.0, 1.1, and 1.2mm diameter holes. The pistons are molded using special methods from Delrin™ material to ensure extreme roundness, while maintaining maximum stiffness and durability.
Shock bodies are CNC-machined from premium Swiss 7075 T6 aluminum and hardened to ensure maximum lifespan. External fine threading allows for quick & easy ride height adjustment. The shocks feature low-profile membranes for super-smooth, precise damping.
The NT1 comes equipped with C5.4 springs in the front to provide maximum stability and steering, and C4.0 springs in the rear to provide maximum traction and cornering speed.
The NT1 springs, like all other XRAY springs, are manually measured, selected and matched into pairs to guarantee precisely equal length and damping characteristics.
The battery holder has been modified for use with most common LiPo or LiFe batteries.
The receiver battery pack can be easily removed from below the fuel tank by a quick access composite cover at
the bottom of the chassis. Optional graphite cover contains a special CNC-machined pocket in which to place the
batteries, allowing the batteries to sit as low as possible. The main feature of the graphite cover is its integrated
Multi-Flex Technology™ functionality to additionally reinforce the chassis in the vertical plane.
Anti-roll bars are manufactured from special spring steel material and are included to stabilize the car at both front and rear.
Wire anti-roll bars: Recommended for use at smaller, more technical tracks when the car needs to quickly change
direction and transfer weight from side to side. The thickness of each anti-roll bar is laser engraved for easy
identification. Anti-roll bar wires of different thickness are optionally available for fine-tuning
Different wire and blade thickness anti-roll bars are optionally available:
Blade anti-roll bar: Recommended for use at long, fast
tracks when the car needs maximum cornering speed.
Diving in corners is reduced, and the car will maintain
maximum speed. The hand-ground front anti-roll bar
blades are manufactured from HUDY Spring Steel™ to
ensure the highest possible life. The anti-roll bars are
easily adjusted using a small 1.5mm hex wrench.
XRAY 3S SPRING-SET (2 pcs) Front = Rear
Reverse Clutch Set.
The new reverse clutch design provides smoother and faster acceleration, while increasing the lifetime of the clutch shoe.
Easily-adjustable 3-shoe XCA (XRAY Centrifugal-Axial) clutch features clutchbell, clutch nut, flywheel nut and thrust bearing collar made from exclusive HUDY Spring Steel™; hard coated flywheel, clutch disc and spring cup made from premium Swiss 7075 T6.
Lightweight Drive Train.
To improve efficiency, the NT1 features the lightweight transmission parts which have reduced weight but still sufficient strength to transfer the power from the engine to the wheels. The acceleration and super smooth work of the drive train is a distinctive advantage of the car.
The lightweight drive train parts included:
• Lightweight Front Middle Shaft - HUDY Spring Steel™
• Lightweight Diff. Outdrive Adapter - HUDY Spring Steel™
• Lightweight Diff. Outdrive Adapter Long - HUDY Spring Steel™
The front bulkheads were updated to accommodate the new front wire anti-roll bar system as well the new muffler mounting system.
Front Lower Arm.
The front lower suspension arm was updated and modified to mount the new front wire anti-roll bar.
The front foam bumper was updated and modified to accommodate the new front wire anti-roll bar.
The rear drive train features dogbone drive shafts which help to generate more traction for the car. To accommodate the new dogbone style drive shafts, the rear wheel axles were also updated.
The new aluminum wheel hubs are CNC-machined from Swiss 7075 T6 and additionally black coated. The aluminum wobble free hex mounts allow perfect and secure wheel mounting.
New updated car holder features an eyelet which allows the fuel tank opener string be captured securely and ensures more consistent refueling.
The adjustable side belt tensioner is captured on a graphite plate mounted to the side of the radio plate holder. The smart design allows the side belt tensioner to be easily adjusted, or easily removed for engine removal.
When it comes to setting new standards in the RC industry, XRAY is always at the forefront for bringing new and innovative
engineering ideas and solutions, raising the bar and quickly becoming a new market standard for others to follow.
XRAY's innovative Multi-Flex Technology™ (MFT™) was originally designed for 1/10 electric touring cars, and has resulted
in some of the most significant milestones in touring car development in the past few years. This innovation not only
received numerous awards and honors, but it has proven to be a distinct competitive advantage at racetracks worldwide...
helping XRAY dominate races at local and national levels.
The NT1 was the first nitro touring car featuring the flex setting. With the optional Multi-Flex™ 1-piece engine mounting system the flex can be easily adjusted for various racing conditions or to fit different driving styles.
Use stiff setting for high-traction tracks where a lot of steering and car response is required.
Use medium setting for medium-traction tracks. This setting offers good balance between steering responsi-veness and traction.
Use soft setting for low-traction, dusty tracks. The car will create a lot of traction with this setting but will have less steering and response compared to stiffer setting.
The standard 2-piece engine mount was designed and tested to allow the right amount of chassis flex to suit most driving styles and racing conditions. For specific racing conditions or driving styles, the middle of the chassis can be additionally reinforced by installing optional MFT™ 1 piece engine mount which features reinforcing legs both front and rear, reinforcing the chassis and stiffening the flex. The MFT 1-piece engine mount can be additionally mounted using graphite braces to the rear bulkheads and/or to the front holders next to the battery packs, creating a very solid and stiff platform.
Radio Plate Multi-Flex™.
The flex of the radio plate can be now adjusted independently from the chassis flex which allows super fine tuning.
Using the bushings in the back the radio plate can be mounted to the mounts either fixed or with flex. It is suggested to use the flex setting for low traction tracks as the softer car will generate more traction. The fixed radio plate mounting is suggested for high traction conditions.
Front optional graphite radio plate allows stiffening the front part of radio plate and changes the flex characteristics of radio plate as well. Radio plate without brace allows a lot of in corner steering. The brace makes the car more stable and easier to drive under high grip conditions or when the tire additive is used.
Lowest CG Platform.
Thanks to the very intelligent design concept and engineering, all parts are positioned ultra-low to create the lowest-possible CG resulting in super-stable and precise handling.
Premium & Exclusive Materials.
The NT1 is luxury model racing car and as such features only the most premium materials: premium woven graphite - exclusive top-secret HUDY Spring Steel™ - high grade Swiss 7075 T6 - high-tensile heat-treated steel and aircraft aluminum - and XRAY's self-developed and formulated composite compounds. All is premium and unique on the NT1.
Color of the parts may vary.
The super-lightweight bulkheads have a very clean and lightweight design to create the lowest weight and CG, making the NT1 easy to service and retaining easy access to all parts. The bulkheads create a super-solid platform where all parts are mounted; a special composite mixture was developed to allow multiple assembly/disassembly without stressing or wearing the parts.
The main advantage of the composite bulkheads is that they absorb vibrations from engine and create a natural flex which is the reason the NT1 is one of the best handling nitro touring cars.
Easy Diff Access.
The smart design of the NT1 allows super-easy front and rear diff access. The front diff can be accessed by removing 4 screws. In the rear, removing the 4 top screws and 2 rear shock tower screws allows the rear diff to be removed.
Integrated Belt Tension.
Both front and rear bulkheads feature integrated eccentric bushings which allow quick & easy front and rear belt tension adjustment.
Compact lightweight radio case features a clean design and layout. The radio case is attached to the side of the radio plate and will fit any standard-size receiver and optional switch with water resistant rubber cover.
The quick-set 2-piece engine mounts are CNC-machined from premium high-strength aircraft aluminum. Separate engine mounts can be purchased to allow you to have all engines pre-installed with engine mounts for quick & easy engine exchange.
Gear Mesh Adjustment.
The intelligent engine mount design allows you to set and fix the engine position for optimum gear mesh adjustment. Thanks to the specially rectified shape of the teeth the gears have always the same gear mesh which ensures that the engine can be in the same position and there is no need for engine movement. After initial gear mesh is set, the engine position is 100% held in place and the engine can be installed/reinstalled any time without any need for any further gear mesh adjustment.
A strong, highly-efficient brake system is created thanks to focusing on all of the smallest details. The laser-cut, precision flat-ground ventilated steel brake disk allows fade-free braking in conjunction with the special high-grip brake pads installed on the laser-cut brake plates. The brake disk is small and slim, making it very light.
The precision hand-grinding on flat grinding machine allows true, wobble-free rotation. Brake inputs are transferred precisely to the brakes thanks to the ball-raced super-smooth brake cam. The alu brake cam is machined from hard coated, black anodized 7075 T6 aluminum for better durability and both brake disk and brake pads are specially heat treated for maximum lifespan.
