The more direct response of a shaft drive system gives competitive Off Road racers the extra control they need. In Off Road racing, throttle response on rough terrain or in the air is much more important for controlling the car than in an on road environment.2. Using a shaft drive train, meant our designers could ensure a sealed drivetrain that would be protected against the elements and be more reliable over bumps and through the ruts and therefore deliver a higher efficiency.One word about torque steer This is an issue in on road cars with their narrower track, smaller tyres and shorter suspensions. In Off Road cars, however, the mass of the tyres is much higher and the suspension is much wider. Therefore the force created by the rotating shafts is insignificant in relation. Bottom line torque steer is not an issue at all and the advantages of the shaft drive make it the superior system for Off Road. * Faster response & acceleration than belt drive * Superior mid air control * Sealed drive train * Low friction components * Not affected by torque steerCHASSISDouble Deck DesignThe Cyclone D4 WCE features improved weight distribution for better balance, even greater mid air control over the jumps and lower lap times for racers. It's hard to improve on one of the fastest kits we make, but our designers have pulled it out again!The foundation of the Cyclone D4 is its sturdy double deck chassis. Made from woven graphite because of its low weight and high strength, the lower chassis is 2.5mm thick and the front and rear upper chassis pieces are each 2.5mm thick. Connecting the upper and lower chassis are the front and rear moulded composite gearboxes and the aluminium motor mountmiddle bulkhead.To make sure the chassis is extra stiff and allows the suspension to do the work it's designed to do, the upper decks are held in place with a total of 11 flat head countersunk screws. The screws are arranged in a fully symmetrical pattern to minimise the effects of tweak on the suspension. Finally, a unique fan mount is included to help keep your motor cool in the toughest of conditions. * WC Edition features improved weight balance * Super stiff double deck layout * Strong light woven graphite * Fully symmetrical to minimize tweakPrepared for the Latest ElectronicsThe lower chassis is as narrow as possible to place the weight as close to the center line of the car as possible. This improves the speed of weigh transfer for faster cornering.Because of the clean layout there is enough room to easily fit any current electronics package, whether brushless or standard brushed system.The motor fits into a large cooling cutout on the main chassis to allow it to get plenty of air, and to let it sit as low as possible in the chassis.Fitting the batteries is very easy, too! The saddle pack style arrangement makes sure you get equal weight distribution and the moulded battery trays allow mounting the battery in two positions, all the way to the rear or slightly forward. This lets you tune the weight balance of the D4 for extra rear traction or more steering. Convenient straps hold the battery in place securely and allow you to quickly install and remove the batteries simply by removing body clips. * Adjustable saddle pack layout for perfect weight distribution * Takes all the latest bushed or brushless systems * Motor cut out for low motor position and exra cooling * Everything mounted directly on the lower chassis for low center of gravityHardwareKeeping everything in place on the chassis are high quality Japanese made hex head steel screws. The high grade steel resists breaking and the precision cutting ensures the screws tap the carbon plastic properly, letting you go through rebuilds without wearing the threads out.All the screws feature a hex head which looks great and makes the car much easier to work on.The standard steel ball ends are heavy duty and feature long threaded shafts to allow infinite adjustments with a selection on aluminium shims.Cool purple anodized light weight shims are used throughout for camber link, bump steer and Ackermann adjustments. * Hex head screws * Steel ball ends * Aluminium anodized shimsSUSPENSIONNew front and rear shock towers are supplied in the Cyclone D4 WCE kit, featuring extra material around the mounting screws and a new button head screw design for the front shock tower to improve durability and crash resistance.From the one piece aluminium front suspension bulkhead to the Infinite Roll Centre adjustments, you'll surely appreciate the effort that went into the suspension design of the D4.In particular, the front end of an off road racer has to deal with quite a lot from pointing the car in the right direction, to powering the car through the middle of a tight turn, and even correcting the angle of the car in mid air, there are many jobs it's entrusted to do, and it must do them all very well if the car is going to be a success! This is why Hot Bodies engineers spent as long as they could perfecting the design of the front suspension, to make sure everything was correct and is ready to go right out of the box for today's advanced racing drivers.ShocksThe Cyclone D4 WCE features all new shock absorbers, designed to be easier to assemble and maintain. With easy bleeding options and improved upper and lower shock caps, you can rebuild the shocks faster and they will also be more consistent while lasting longer between rebuilds. All the metal hardware is hard anodized for durability.Our designers spent a long time getting the shocks in perfect order for high level off road racing.The hard anodized 7075 shock bodies are very tough, made from the strongest aluminium alloy used in RC today. Each shock body is also threaded for infinite ride height adjustment. The fine pitch of the thread allows you to make extremely small adjustments so you get the perfect ride height for any track you race on! Knurled shock collars allow you to get a good grip for easy adjustments and o rings in the collars prevent any unwanted movement.The top and bottom of each shock are enclosed with threaded aluminium caps. The top shock cap secures the mount in position, while the bottom shock cap contains a double o ring shaft seal. Aluminium is used for the bottom cap for increased durability, lower maintenance and ease of rebuilding. However you prefer to fill your shocks, from the top or from the bottom these shocks can accommodate you! To prevent leakage both caps feature an o ring seal.For easy assembly the kit includes a set of tailor made shock building tools for the top and bottom caps.Each shock shaft is made from tough stainless steel, and feature threads at both ends at the top to hold the shock pistons in place and at the bottom to attach the bottom shock mount.For ultra fine tuning of the damping characteristics you get three different shock pistons with the kit. If this isn't enough for you there is also a set of blank pistons to drill your own piston holes!Ride height limiters are included with the kit as well, allowing you to fine tune the suspension to your exact driving style, track conditions and particular needs. * WC Edition features new hard anodized shock bodies and hardware * New improved upper and lower shock caps with bleed screw * Hard anodized threaded shock bodies * Top and bottom threaded caps * Aluminium shaft seal cartridgeSprings The D4 comes with HB black off road springs as standard, which are the softer option of three different spring rates that are available for the car. Each spring is precisely tuned for off road racing and features ground flat ends, an all black finish for stealthy good looks and identifying paint marks at one end. * Ground flat ends * Colour coded * Three grades availableOptimized GeometryIn months of extensive track testing our HB race team and engineers have developed what we think is the finest off road suspension geometry available today wide track suspension arms, inverse steering block design, vertical ball end placement and of course full adjustability to name just a few highlights.Suspension MountsThe front lower suspension arms are mounted to a one piece aluminium bulkhead which directly bolts to the chassis.The rear lower suspension arms are mounted to independently adjustable aluminium pivot blocks.With the suspension components attached to the chassis independently of the gearboxes and other parts, you can be sure that the suspension does all the work of absorbing landings and keeping the tyres on the ground. No forces are transferred from the suspension to the drive train or vice versa. * One piece aluminium front bulkhead * Rear aluminium pivot blocksHinge PinsThe new front bumper is wider to protect the hinge pins, and securely encloses the mounts for the new front sway bar.All hinge pins are made from durable stainless steel and are held in place without e clips, making removal of critical suspension parts easy and quick. Rubber bushings in the front bulkhead and rear pivot blocks hold the hinge pins in place and absorb shocks that might otherwise bend the pins or break other parts of the suspension.Set screws hold the outer hinge pins in place, completing the 'No e clip' suspension design and making the car overall easier to work on than other designs. * WC Edition features new wider bumper to protect front hinge pins * Stainless steel * No e clips * Rubber bushingsSuspension ArmsThe Cyclone D4 WCE front arms have extra material added to withstand crashes, bad traffic and rough landings. A ball attachment for the new front swaybar is included on the front arms for easy attachment.Front and rear wishbones feature a sleek aerodynamic design with integrated webbing to make them extra strong. The carbon reinforced composite plastic makes them stiff and resists twisting. The V shape design of the rear wishbones increases stiffness even further and allows the usage of longer stroke shocks. * WC Edition features additional material and sway bar mount ball on front arms * Carbon reinforced composite * Rear V shapeInverse Steering Block DesignThe D4 steering blocks are a marvel of simplicity and design brilliance in their own right. The steering knuckles go around the uprights instead sitting inside a large C hub as in a conventional design.This inverse design allows the use of much more compact, simple, straight forward parts which makes the steering more precise and the construction more durable.Providing the maximum amount of drivetrain efficiency while the suspension is compressed or when the front wheels are steering at extreme angles, Cyclone D4 engineers made sure that the steering kingpin and the universal joint line up exactly. This reduces stress on the universal joints and gives you increased driving feedback as you go through a turn.The huge openings in the uprights for the driveshafts make sure nothing gets in the way of the shafts or the universal joints * Inverse design * Compact and durable * Aligned king pin and universal jointAdjustabilityThe one piece aluminium front suspension bulkhead features built in 7.5 degrees of kick up.The rear anti squat is adjustable with the two independent hinge pin pivot blocks. Placing aluminium shims under blocks varies the anti squad angle to keep all the power on the ground.Variable caster is provided by the 7 or 10 degree both included front caster blocks, and allows you to select the right amount for your driving style. More front caster generates more initial steering into the corner but less steering out of the corner.Front toe is easily adjustable using the titanium steering turnbuckles.Rear Toe in is set at three degrees at the pivot blocks as standard. It is also adjustable through the use of sturdy optional pivot blocks andor rear hubs.Using the Cyclone Infinite Roll Centre IRC adjustments, you'll be able to swiftly and conveniently control your roll centre front and rear. Long ball studs hold the camber ball links in place, and washers are used under the ball studs to raise or lower them as needed for each particular track.The D4 features 2 inner and 1 outer camber link location at the front, and 1 inner and 2 outer locations for the rear.
