Serpent is pleased to announce the release of the Serpent 966, the next stage in the development of the highly successfull 960 platform.
The backbone of the car is the chassis plate, which has been CNC-machined from extremely stiff american 7075 T6 - 5mm aerospace-quality aluminium and sports a wide front opening to adjust the front anti-roll bar. A cooling slot under the engine helps aid temperature control while chamfered edges prevent the chassis from catching on kerbs giving it better overall ground clearance on the track. It houses the battery pack, which is mounted into the newly-designed carbon fibre battery mounting plate and is held in place by four screws, screwed directly into the chassis plate itself. This new 966 plate has also been machined to accept the optional front stiffener plate.
The brake system ensures strong and efficient stopping power. The brake pads consist of two steel plates with the friction material pre-baked to the plates, and the brake disk is made from twin ventilated discs with an air-cooling alu centre.
Lower mounted brake-assembly for lower LCG. Spring-loaded brake-plates slides on polished steel shafts. Ready-to-run brake plate/pads assembly with new friction brake material. The ball-raced hard anodized brake-cam push the 2 larger pins which are seated in the aluminium bracket, against the brakeplat, to create very smooth and even pressure to the plate.
Main rear brackets
Anodized, cnc machined, aluminum main rear axle supports with coated alu eccenters; more rigid, better rear axle support for a very true running rear shaft, easy belt-tensioning, easy access for maintenance. With the eccenters you can choose 3 positions for rear- belt tensioning. By removing the eccenter on one side the rear shaft with pulley and belt can be accessed very easily. Main rear supports are machined maximum to reduced weight, but retain rigidness at the same time. Pins are pre-pressed into the bottom of the brackets which then seat into the positioning holes in the chassis. Precise and secure.
Improved RCC Shock Absorbers
The RCC shock absorbers are super-smooth and very easy to build.
The front axle is made from high-grade aluminium and contains the best quality one-way bearings lubricated with one-way lube. This ensures a consistent drive to the front Spring Steel drive cups.
Front Anti-roll Bar
The Serpent 966 comes standard with an adjustable front anti-roll bar. By rotating the 2 blades, you can easily adjust the stiffness. Centering with an improved adjuster eccentric.
Front Bumper and Body Mount
The front body mount of the Serpent 966 is screwed down along with the bumper, which allows for some flex in the body post mounts whilst maintaining the stiffness of the overall assembly. The body mount is held further through two screws mounted from the side.
These Wide offset (WOS) steering blocks can be used in 2 different configurations by swapping the side of the car they are mounted on. These changes, depending on the side the steering blocks are used on, will either give you more turn in on corner entry, or more on power steering at corner exit.
The front anti-roll bar levers, that are combined with the down stops allowing for easier tweak. They placed inwards, inside the bearing-blocks, which makes them more effective due to less flex. The front lower arms accommodate the front anti-roll bar position.
Adjustable Front Belt Tension
A great feature is the ability to adjust the tension of the front belt. The simple-to-use bearing eccentric holders allow for quick and easy setting.
Front Shock Tower
The front shock tower of the Serpent 966 is made from 3mm carbon fibre, which makes this part ultra crash resistant. The front shock tower also features two shock mounting positions to enable you to fine tune your car for any track conditions.
Driveshafts / wheelaxles
Serpent use only the highest-quality drive train in their cars. The 966 car comes supplied with the finest Spring Steel drive shafts capable of withstanding constant punishment; these shafts are ultra durable and very stiff allowing you to put all your power to the tarmac.
Made from Spring Steel, these polished 8.5mm pivot balls are virtually unbreakable and ensure the smoothest suspension movement possible.
Adjusting nut for pivot balls
These adjusting nuts are made from Nylon and replace the previous aluminium nut with plastic insert which will not only makes assembly easier, it also reduces un-sprung weight. Reducing the parts used at this point also reduces side play so it makes for a more precise handling car and because the material used is self-lubricating the movement of the pivot ball will remain smooth throughout use.
Aluminium middle bracket
The Serpent 966 comes supplied with an aluminium middle bracket as standard. Replacing the standard composite version, the new part is much stiffer and so reduces flex in this axle which prolongs the life of the belts and pulleys.
Radio Plate Support Bracket
The radio plate support bracket, placed directly in front of the engine, also acts as the mounting point for the roll over bar. The roll over bar is shaped in such a way that it optimizes the car's weight distribution when in your hand.
Battery Mounting Plate
The carbon fibre battery mounting plate has been designed to be able to accommodate many different battery pack configurations, including the traditional 5 cell pack. The battery mounting plate is made of a 2mm black carbon fibre and is mounted to the chassis plate by four countersunk screws.
Another feature is the two carbon-fibre side mounted chassis stiffeners. These plates form a strong bridge between the front and rear section of the 960, and are mounted directly to the radio plate bracket and to the rear bulkheads. They increase the chassis stiffness, an essential condition to make effective use of the sophisticated suspension adjustment options.
Throttle Servo Mounting
The 966 offers two possibilities for the mounting of the throttle servo, first of which is the the traditional stand-up throttle servo layout. To lower the cars centre of gravity there is also an option to mount the throttle servo in a lay down configuration. This moves the heavy motor and other parts of the servo lower and to the inside allowing for better weight distribution and C of G.
Serpent have supplied the 125cc fuel tank with a new silicone rubber seal for the AFL fuel tank lid that prevents leakage and thus provides more consistent engine performance. Made from silicone rubber, the new seal has been shaped to create a perfect seal around the opening of the tank and allowing the tank lid to close fully.
The receiver on the Serpent 966 can be mounted in two different positions, depending on whether you choose the laydown throttle servo mounting or the traditional upright throttle servo mounting.
Steering Servo Mounting
The steering servo is mounted on the right side directly to the bottom of the radio plate and hangs free from any other item. The steering system uses a centrally mounted servo-saver, which features adjustable spring tension and comes with four Ackerman options, through the use of inserts, to help fine-tune the 966 steering characteristics. Adjustable steel track rods with left and right threads are standard.
Made from Spring Steel, the solid rear axle is very durable and ultra strong providing a perfect base to mount the rear drive pulley. A steel pin secures the pulley and an o-ring keeps it in place.
Adjustable Rear Roll Center & Camber Rise
On the Serpent 966 the rear roll centre is adjustable through the use of offset composite inserts, which position the wishbone pivot pins of the lower wishbones.
Rear Anti-roll Bar
The rear anti-roll bar on the Serpent 960 '08 is ball-raced for extra precision and more accuracy when you change the setting of the, newly upgraded softer, aluminium adjustable anti-roll bar which comes as standard in the kit.
Rear Body Mount
The rear body mount on the Serpent 966 can be connected in several different ways to increase or decrease the downforce transmitted from the body to the rear wheels. There are longer body mount arms, that are mounted to the rear uprights at axle level which provides more down force to the wheels. The whole assembly is also free from binding, meaning there is no restriction of the movement on the suspension.
The rear end geometry provides excellent rear end grip and provides a very stable car both under braking and at exiting corners. The OS 2 uprights sport small bearings to reduce un sprung weight, 3 upper arm mounting positions and the possibility to use shims for changing the roll centres. Strong lower wishbones with sufficient material around the pivot pin and pivot balls, and the upper arms allow easy adjustment of the camber and camber rise. Longer body mount arms provide more down force to the wheels yet have no binding due to their mounting position.
Rear Shock Tower
The rear shock tower of the Serpent 966 is made from 3mm carbon fibre, which again makes this part ultra crash resistant. The rear shock tower sports 4 shock mounting positions to help you fine-tune your cars handling track side.
Quick Release Wheel System
The Serpent 966 comes standard with both spring-loaded aluminium quick release levers and fixed alu nuts (with o-rings).
Drive Belt System
The Serpent 966 uses three Kevlar-reinforced main drive belts, driven by a series of composite pulleys mounted on aluminium pulley adapters. This allows for a very smooth and efficient drive system that can withstand severe punishment.
Engine Mono block
The strong engine mono block that takes advantage of the extra space where the engine is mounted on the LCG (Low Center of Gravity) chassis plate. As well as the benefits of the mono block system, to stop the engine flexing, the block allows the motor to be mounted lower in the chassis by 2mm. Due to the engine being lowered the car is now supplied with a smaller diameter flywheel.
The Centax-II clutch system features large ball bearings (a 5x13mm and a 5x10mm) as well as a large thrust bearing (5x10mm). This increases durability and provides ultra-free movement of parts. Featuring an externally-adjustable clutch gap spacing method, and an innovative pivoting flyweight system.
Exhaust Mounting Spring
Using a spring-type mounting wire to isolate vibrations, the spring is attached to the car by means of an aluminium mounting post attached to the radio plate.
The 2-speed gearbox is race proven and is easy to adjust and assemble thanks to its simple design. The gearbox features large ball bearings (a 6x10mm and a 6x13mm) for extra durability and smoother rotation. The gears are mounted to the carriers with three small screws and come in a full range of gears available in combination with pinions for the Centax-II clutch.
Supplied with sealed high-quality lightweight bearings throughout, the drive train is very efficient and runs very smoothly.
The Serpent 966 is a top-level competition racer and is therefore fully adjustable. The racer can change numerous settings easily and effectively, including the suspension geometry. The down stops can be easily accessed and easily adjusted with optimum effect. Caster, track-width, toe-in, camber, camber rise, and wheelbase can also be adjusted with ease, as well as the front and rear roll-centre and rear body mount mounting angle.
Due to the front wishbone configuration, it is possible to very easily adjust the car's wheelbase through the placement of 1 upper and lower caster clip on each side of the car.
To allow you to build your car with the greatest of ease, Serpent supplies a full colour instruction manual, this includes all the exploded views and options to locate part-numbers easily.
The Serpent 966 comes in a very small carton box, with full color box-top.
