Ball-bearings
High quality, high precision lubricated longlife NSK bearings made of hardened steel throughout.
Fasteners
High quality steel fasteners for durability. Minimised number of different screws for ease of assembly and maintenance
Chassis
Carbon fibre chassis in 2.0mm thickness. Countersunk holes and designed to have equal flex left to right.
The screws to set ride height are adjusted from the bottom of the chassis with just one screw in front and one in the rear with a simple and effective mechanism to adjust the rideheight.
Battery mounts
State of the art battery mounts made in aluminum and carbon fibre and allow to position the battery more tot he front or back and secure it well in place. Shorty lipos can be placed centered, in front or rearward position.
Floating servo mount
The servomount is a combination of a carbon brace and aluminum posts. The carbon brace is bolted to the central brace and does not touch the chassis to prevent any flex influence.
Steering system
The ballraced aluminium steering system consists of an inversed leversystem to better control the Ackermann setting. The angle difference between the inside and outside wheel is a lot more linear than in conventional designs.
Drivetrain
In the front the 4X features durable spring steel double joint cardan shafts, combined with the blade type spool.
In the rear lightweight coated aluminium cvd style dogbones are used with durable spring steel wheelaxles.
Both front and rear wheelhexes are a lightweight aluminium design
Steeringblocks / uprights
In the front and rear the same steeringblocks/uprights are in use. The pivotball system allows for easy and quick set-up changes and works very smoothly. In the front there are 3 Ackermann positions and shimming below the steeringrod can be used for fine tuning of the bumpsteer characteristics. In the rear the system allows to set Reactive Rear Steering. This RRS system allows for a change of toe-in while the suspension compresses and thus increases cornerspeed.
Wishbones / pullrods / rockers
The lower wishbones are the same front and rear and the same goes for the upper arms.
The lower arm mounts of 2 short pivot pins and the mounts have a lot of space to play with wheelbase by using clips. The lower arms also feature 2 downstop screws front and rear.
The upper wishbones allow quick caster changes with clips and run on an easily removable long pivot pin.
Rocker and pullrods system
The pullrods connect to the upper arms and operate the ballraced aluminium rockersystem which activates the dampening systems for heave and roll action. All trackrods and pullrods are made in coated lightweight and tough 7075 T6 aluminum.
Aluminium upper hinge pin holders and alu stiffeners
The assembly is split in 2 sections to allow for easy maintenance and change of settings. The inner top brace connects both sides and creates a very strong structure preventing tweak. The topbrace is connected to the lower brackets with alu stiffeners. These stiffeners can be easily removed in case more flex is needed.
The assembly rest on roll center spacers. To add additional shims for changed cambergain and rollcenter is a simple and quick setting.
Bumpers and bodymounts
In the front a strong bumper-set using a large size but light foam bumper which is sandwiched between the lower composite bumper and upper graphite holder. The flexible moulded bodyposts with swivel-system go all through. Optional body height systems are available.
In the rear the lower bumper will prevent damage to the rear of the 4X and the moulded bodyposts with swivel system mount on a thick and stiff carbon plate, which is part of the strong rear end assembly.
Suspension
In the 4X car the heave and roll of the car operate and are set independently. The front and rear end of the car are almost identical in design and share many of the same parts front and rear, so you need less different spares.
Heave damper
There is one have damper in the front and one in the rear and they work in the same way. The heave damper is located just above the chassis to lower the center of gravity. Pullrods which are connected to the upper arms link to the rocker system. The rocker system is connected through a swivel unit to the heave damper and roll damper unit. The small heave damper has a small strong shockabsorber spring and is oil filled. Different oils and springs can be used for setup work, influencing mainly bump and on-throttle/off-throttle transitions. It is easy to access from the bottom of the chassis.
The ride height is set with a simple one screw setting in the chassis, both front and rear.
Roll damper
The roll damper unit consist of an oil body for dampening with a through shaft and has a small spring on each side. This unit controls the roll of the chassis, it works as an anti-roll bar.
Different oils and springs can be used for setup work. The whole unit comes out after releasing just 2 screws. One can have complete rolldamper assemblies ready to change settings in seconds.
Chassis stiffner
The 7075 T6 central alu brace takes care of the connection between front and rear end and prevents unwanted tweak and takes care of torsional stress. For most situations it eliminates the need of a topdeck.
Motor mount
Extremely low 7075 T6 aluminium motormount which doubles up as connector for the midshaft holders, connection for the RRS system, holder for the alu stiffener and connector to the central brace, all-in one.
Gear differential
The nicely shaped renewed gear differential features new internal gears which makes it supersmooth. The compact and light unit holds a good amount of oil to deliver stable performance throughout the run. It is fast and easy to take out and re-mount the differential.
Front spool
The coated aluminium front spool with lightened springsteel outdrives is a blade type which ensures superb handling and durability throughout the race, and it is easy to exchange blades as needed. It is fast and easy to take out and re-mount the spool. The springsteel is strong enough that you can easily finish your run even with a broken blade without damaging the outdrives too much.
