The Serpent 835 follows in the prestigious footsteps of the World and National Champion Serpent Impact M2 Challenger. Incorporating many of the new features the Serpent Race Team developed, the ‘835’ will continue to be the choice of champions in the 1/10 scale 235mm class for years to come.
Refinement is the key word when describing the Serpent 835. Heavily based on the World and European Championship winning Impact M2, the car has been further enhanced with changes to the lower center of gravity, chassis stiffness and the cars overall weight.
The SERPENT 835 features the following new details: new chassis - chassis-mounted battery pack - new radio plate lay-out - new fuel tank (same as 705) - new alu. radio plate bracket - new carbon fiber side chassis stiffeners - modified rear blocks - new light-weight 2-speed gearbox - new CENTAX II - new front and rear shocktowers
The newly designed radio plate, constructed from 2mm woven carbon fiber, features a new layout while at the same time increases the stiffness of the entire chassis. The steering servo on this ultra compact radio plate is mounted in a conventional upside down manner, as is the throttle servo. The radio plate also sports a nylon receiver mount placed beside the optional transponder holder’s mounting point.
The Serpent 835 features two carbon CNC machined shock towers mounted to the front and rear. Providing optional shock mounting positions, these towers are a crucial tuning element to help you find the perfect setup for every track condition.
The radio plate support bracket has been beautifully machined from a single block of aluminum and whilst supporting the radio plate also increases overall chassis stiffness. The support bracket also provides the mounting points for both the rollover bar and the chassis stiffeners.
A completely new 75cc fuel tank has been developed to allow for the new mounting of the battery pack, which is placed directly beneath the tank. Top mounted using rubber covered aluminium mountings to isolate from vibrations; it is held in place by small body clips. This new tank is fitted with another of Serpents innovations, the ‘AFL’ fuel tank lid. It contains an air chamber to prevent the backpressure tubing being blocked by fuel being forced back down it at high speed cornering. Also new is the lightweight pick up filter, now made from a special polypropylene.
The battery pack for the Serpent 835 is mounted into an easy to remove composite battery holder and placed in the chassis plate directly under the fuel tank. This gives the 835 the lowest possible center of gravity and lowest polar moment due to the weight being in the direct center of the car. The battery holder is designed to hold 5 Triple-A 1.2v cells, (not included). A pre-made battery pack is available as an option.
The newly designed chassis plate has been constructed from 4mm T6 aerospace quality aluminum to provide both strength and stiffness while at the same time its optimal design ensure that it is kept lightweight. The chassis plate comes with three cooling holes just under the engine to aid temperature control. It houses the battery pack, which is mounted into the plate and held in place by composite mounting points. All screw holes are countersunk to ensure no obstructions when the chassis is running low to the ground.
Another unique feature, the 2 carbon fiber side mounted chassis stiffeners. These plates form a strong bridge between the front and rear section of the 835, and are mounted directly to the radio plate bracket and to the rear-bearing blocks. They increase the chassis’ stiffness, an essential condition to make effective use of the sophisticated suspension adjustment options. The left chassis stiffener also houses the adjustable ball-raced belt tensioner, a simple and very effective system.
The new 2-speed gearbox is an evolution of the first 2-speed system Serpent invented many years ago. Now in a lighter and much more efficient form, this gearbox is easy to adjust and assemble thanks to its simple design. The gearbox features larger 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 different colors for easy recognition in your toolbox. A full range of gears is available in combination with pinions for the Centax-II™ clutch.
Only the second design of the clutch system created by Serpent in the early nineties, the Centax-II™ features larger ball bearings (a 5x13mm and a 5x10mm) as well as a larger thrust bearing (5x10mm). This increases durability and provides ultra free movement of parts. Featuring an externally adjustable clutch spacing method, the new Centax™ system also sports a new stiffer spring (1.8mm) and a completely new pivoting flyweight system. Standard is the new XP clutch shoe which, when used in combination with all the other new parts, provides extra punch and better clutch consistency.
The Serpent 835 features a graphite rear body mount with adjustable body post mounting points to ensure the optimum body mounting is achieved.
Serpent’s famous 4-step externally adjustable shock absorbers now come with keyed shock pistons, which gives the shock a very positive clicks when selecting another setting. The Serpent 835 comes supplied with yellow springs and Serpents ultra consistent 30W quality shock oil.
The Serpent 835’s steering blocks are constructed from a very strong composite material and sport ridges for increased strength and rigidity.
Using a spring type mounting wire to isolate vibrations, the spring is attached to the car to the front bearing block and secured in place with a grub screw.
The brake system consists of 2 steel plates merged with braking material ensuring efficient stopping power to the single disc. The braking action utilizes a cam system (the brake cam is hard anodized), which further ensures the smoothest braking action.
The front bumper of the Serpent 835 is constructed from high impact resistant composites and can easily survive big crashes and at the same time protecting the rest of the car from damage.
As with all cars in the Serpent range the Serpent 835 features independent double wishbone suspension.
Supplied with purple sealed high quality lightweight bearings throughout, the drive train is very efficient and runs very smoothly.
The front axle is made from high-grade aluminum and contains the best quality one-way bearings lubricated with Serpent one-way lube. This ensures a consistent drive to the front HUDY™ spring steel drive cups.
Made from HUDY™ spring steel, the front and rear wheel axles are very durable and ultra strong. These are a precision fit for the main bearings to ensure consistent drive to the wheels.
The Serpent 835 is supplied with the innovative FPS adjustable ball differential. Using high-grade stainless steel diff balls provides the smoothest action possible and due to ease of adjustability further ensures that the optimum settings can be achieved and maintained for any track condition.
Made from HUDY™ spring steel the solid rear axle is very durable and ultra strong providing a perfect base to mount the rear drive pulley.
Made from HUDY™ spring steel these polished 8.5mm pivot balls are virtually unbreakable and ensure the smoothest suspension movement possible.
Serpent use only the highest quality drive train in their cars and this car is no exception. It comes supplied with HUDY™ 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.
Serpent uses Kevlar reinforced drive belts. The Serpent 835 uses three main belts, driven by a series of composite pulleys mounted on aluminum pulley adapters. This makes for a very smooth, efficient and durable drive system.
The Serpent 835 comes supplied with an adjustable front anti-roll bar and top mounted 1.5 mm rear anti-roll bar.
The Serpent 835 comes standard with spring loaded aluminum quick release levers. This reliable and time saving system enables very quick tire changes during long distance races, allowing you to get back on the track in as little time as possible.
The Serpent 835 comes complete with a full set of the finest quality 35° shore Ellegi Technics™ foam trued and glued on Serpents ultra rigid BBS style yellow wheels.
To enable you to start your Serpent 835 with the greatest of ease Serpent provide the necessary alignment brackets for your Powerstart™ starter box.
The Serpent 835 has been designed with the highest level of competition in mind and is therefore fully adjustable. The racer can change numerous settings easily and effectively, including the suspension geometry. The up- and down stops can be easily accessed and easily adjusted with optimum effect. Castor, toe-in and camber can also be adjusted with ease.
To allow you to build your car with the greatest of ease, Serpent supplies a full color instruction manual and set-up guide. Also supplied with the car is a separate brochure containing all the exploded views and latest optionals as well as a Serpent 835 decal sheet.
