The Cobra Race Buggy is a new innovative design based on 15 years of off-road racing experience.
It is a mixture of new and current concepts to provide a substantially better overall package. The balance left to right and front to back has also been improved over current designs. In turn provide a larger tuning window without loss in drivability. With most new competitive buggies being put on a diet, you will not be disappointed, as the S811 comes in at 3300 grams, fully loaded with all the standard items. The philosophy was simple, how can you create a car, which will take an average driver and transform him into a great driver. The end solution was to provide him with a product that will work as one harmonious unit together, all items functioning in unison.
With so many features all wrapped up in one bundle, here are some of the items you can expect to find on the S811 Cobra
Improves overall ground clearance on sides for minimal chassis dragging. This is an improvement for Jumping and cornering over uneven ground. With less mass out wide the car will pitch less in the corner, but also stay straighter in quick left to right cornering.
Machined chassis 3mm
Light weight chassis helps minimize weight and improve overall vehicle performance. Countersunk holes. Anodised in titanium color and laser engraved Cobra logo.
All suspension mounts are keyed into position
This helps to relieve the mount of any side forces from tumbling in a crash. It take the pressure off the screws and transmission case and puts that force on the chassis.
Most angle in its class, this will provide more clearance for attacking even the most destroyed jump faces. It will insure you can guide your way up the face without scrubbing off any valuable speed.
Helps reduce the lawn dart effect on nose down jump landings. Also helps to prevent scrubbing off speed on moguls, and whoop style bumps
5 mm of wheel base adjustment in the rear from 322.5 to 327.5 mm.
Durable moulded composite steeringblocks with standard 10 degree caster blocks.
Front Steering knuckle assembly
The front roll center can be changed quickly by moving the steering knuckle shims to their appropriate locations.
Inboard Bell crank Steering arm
This is to provide a tighter fit on the body as well as keep the lever and linkage inside the car. It will aid in the prevention of damage to the steering system
Zero scrub radiuses on steering knuckle
This feature helps reduce the jacking effect created by your steering knuckle offset. It provides a more direct feel while keeping the cars chassis more level while turning.
With the design of the steering bell cranks when changing the Ackerman you will not need to adjust your steering tie rods. You simply will only need to adjust your end points on your radio..
Angled Bell cranks
The bell cranks are angled to reduce the angle of difference between the total caster and steering plane. Therefore you will have less bump steer and a truer steering Ackerman through the entire range of suspension
CNC machines suspension brackets front and rear. Very strong and durable, yet lightweight design, keeping the pivot-inserts well captured. Anodised and laser-engraved.
Symmetrical inner pivots
Front and rear pivots are in the same plane. This helps keep the care more neutral under cornering.
There is a range of different eccentrics you can use to adjust your kick up in the front of the vehicle as well as the anti squat in the rear.
Based on the bell crank design the rod length has been optimized to be as close to the same length as possible to further reduce bump steer.
Reduces unwanted debris from destroy servo saver faces. Which will prevents any sort of premature servo damage.
The front roll center can be changed quickly by moving the steering knuckle shims to their appropriate locations.
This is a quick and easy way to adjust the left and right tweak of your sway bar.
Front and rear anti-roll bars made of spring steel wire and size indicated with engraving.
Anti-roll bars are ballraced for effectiveness and smooth operation.
A variery of optional ones available, also as sets.
All camber links, steering links and steering servo links have been trapped. This will help prevent any ball cups from popping off.
Although this has become the industry standard you will enjoy all the benefits of this compacted bigbore design with large o rings and superb bleeders. The larger o rings provide less overall pressure and a better seal without all the dragging on the shock shaft.
Laser angraved hard anodised tops.
Threaded shock bodies
This is for reducing parts in your pit bag. No more clips to loose. It helps adjust in much finer increments.
Oversized 4mm shock shafts
Reducing damage to shock shafts from hard jump landings or impacts.
Shock boots with bump stop
Shock boots have been designed to increase life, seal and utilize rubber as a cushion to prevent damage to suspension components.
Shock spring buckets with debris drain and key locator The spring buckets at the foot of the shock have drain holes to get dirt, water and debris out of the usable shock zone. The key locator helps to align and lock the spring bucket into position so it stays put during operation.
4.5 mm thick light alu shock towers improve visual appeal, however also provide lighter weight. Both front and rear.
The assembly is unique as is provides on rigid component that can house all of your radio gear. The removal is just as easy with 6 screws total.
Crimping Antenna mount with rubber water proof cap
With water ever being a problem in outdoor nitro racing. This Crimping design not only will hold your antenna in place, but has a rubber cap to prevent water from sneaking in to your radio box.
Provides more stopping power than you could have ever imagined before with a whole lot less servo power. Also is fully adjustable with 3 types of pistons
O ring type
In turn you can adjust your bias or braking feel to your liking in more ways than ever before.
Fiber Glass disc brakes
Fiber Glass brake disks with oversized front.
Brake plate springs
Will keep the plates spread open to insure not un-wanted dragging of the brake discs.
Helps provide consistent pulling on the brake lever or carburetor if you do not have the linkage perfectly aligned.
By reducing the rotating mass, you can further increase the amount of out of the corner acceleration. In turn your engine breathes easy and consumes less fuel.
This drive ratio will provide amazing acceleration combined with the low vehicle weight. It is a sure win, to help improve fuel mileage
Helps prevent the spur gear from slinging debris all over the inside of the car and especially into the air filter. Works for rain and water puddles.
When overall weight is an issue, why not reduce rotating mass. Equal lenght front and rear. Precision machined spring-steel.
Captured universal joints
The idea here was simple. Guarantees you will finish a race without loosing a pin or set screw. All parts, axles and drive train components have capture pins
All hinge pins are either captured or bolted in place. This insures your chances to finish an hour long main event, while battling for the lead.
Larger 3.5 mm outer rear hinge pins
Better impact resistance in crashes. Provides silky smooth suspension operation and longer pin life.
Hinge pin suspension balls
This relieves stress on the hinge pin when adjusting the kick up, or anti squat. Your pin is free to rotate to any angle without binding.
Durable composite rear uprights with larger size bearings. Dustcovers will keep dirt out and increase lifespan.
In moist or wet dirt situations these mud guards reduce and dirt sticking to the rear drive shafts and shocks.
Allows you to mix and match shoe materials evenly in pairs. Also provides more surface area contact to insure the engagement.
4 carbon shaped shoes are standard ( alu ones optional).
Helps aid in the front to back movement of the pipe when chassis flex occurs. Helps prevent damage to your exhaust gaskets.
Guarantees that you will not loose a wheel nut in a race
Lower rear wing in strong flexible nylon.
The composite rear wing mount, allows to change the angle of the rear wing.

Splash basin on tank top
This helps reduce fuel all over the chassis in the event of a messy pit stop. The basin collects the splashed fuel and guides it safely out the bottom of the chassis
Self centering Fuel tank seal
The fuel tank seal is angled to self guide its way into the bore of the tank. At the same time will provide a seal on the chamfered and flat edges of the seal, providing consistent engine performance from one pit stop to the next.
Built in tank splash guard
Helps prevent fuel from splashing onto your air filter in the event of an overly excited pit man.

Team Sweden: David Hassel races Cobra Buggy and more ... (09/19/2012)
Recently David Hassel from Sweden joined team Serpent . David is a very skilled and talented young driver, who can race both onroad and offroad very well, but his main interest is for 1/8 offroad racing and winning !
Coming from Kyosho before, he races Serpent Cobra GP buggy since late august . His 1st race appearance with Cobra Buggy at the Nordics in Norway went really well, winning the semi-final and finished 7th overall, with speed good enough to be on the podium. 2 weeks ago he joined the Swedish Cup for 1/10 gas onroad and finished 3rd with a borrowed 733. Winter will be good for running indoor 1/8 and 1/10 offroad and also some indoor carpet racing with 411 is planned.
As soon as Serpents next bigger project the 2wd 1/10 buggy will be ready, he will test and race that as well.
For Serpent its great to work with these young, talented drivers to work towards the future !
