Serpent 811 Cobra Sport 1/8 Nitro Buggy

Serpent Cobra 811 Sport 1/8 Nitro BuggyWe knew it was coming but we never expected to see it so soon. Just weeks after revealing their new electric powered Cobra 811 Sport 1/8 Buggy, Team Serpent has announced its nitro counterpart. The new Serpent Cobra 811 Sport GP features many of the high end features of the highly successful Serpent Cobra 811 factory racer but with a price tag a fraction of its size. It features a 3mm T6 aluminum chassis, 3 ultra tough gear diffs, a race clutch and big bore aluminum shocks. Just add your choice of radio equipment, wheels and tires, engine and pipe and you’re ready to race!

Chassis
Chassis plate in 3mm 7075 T6 aluminum , with machined pockets to create flex and or make lighter. Kick-up angle on front for easier landings. Countersunk holes. Slots to locate the front and rear suspension mounts precisely. Angled sides to increase stiffness. Open pockets to access flywheel . Laser engraved Cobra logo.

Bumper
Large rounded nylon bumper that withstands impact after large jumps, and makes landing more suttle. Protects also the front swaybar assembly and front suspension brackets.

Chassis stiffeners
Composite stiffener front and rear, to give extra stiffness, but still allow some flex as needed.

Central disk brake system
Very low and centrally placed brake system for low centre of gravity with glassfibre brake disks, combined with thick steel plates which wont bend under pressure.

Radio-box
Composite radio box which offers space for the lay-down steering servo and the upright placed brake-throttle servo. Sufficient spacers are supplied for correct fitting of the servo’s. The receiver and battery can be placed safely under the large cap. The transponder can be mounted in the central part, between servo and receiver box. The whole assembly including linkages can be taken off easily and fast in one go, when cleaning the car, or doing maintenance.

Servo arms and linkages
The servo arms have a splined insert to have the right fit per brand. The linkages runs very clean and tight and are easy to access to modify settings.

Suspension brackets
Durable nylon suspension brackets. Precision fit for the nylon roll center inserts and pivot balls / pins.

Steering blocks assembly
Composite steering blocks combined with 10 degree C-hubs for precise steering. Steel wheel-axles with large size bearings and larger inner with precision threaded aluminum wheel-hubs . Flanged and serrated wheel nuts to guarantee that you will not loose a wheel nut in a race.

Front suspension
Durable over sized lower suspension arms in strong composite nylon. On the lower side down stops setscrews are mounted. The lower shock-mounting pins are secured with a small grub screw from the bottom.

Front anti-roll bar
The ball raced front anti-roll bar system, consist of a spring steel bend wire, which is guided through the diff-cases and run in ball raced steel adapters. The wire is linked to the lower suspension arm, with a captured adjustable threaded pivot ball, for very precise and low friction operation.

Shock tower and front body mounts
4.0mm thick anodized aluminum shock tower with 3 upper positioning holes for the shocks and and 5 holes for roll-center positions. 1 centrally located adjustable body mount , and 2 forward mounted adjustable body mounts, all with flip-tops.

Angled steering system / servo saver
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

Ackerman plates
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.

Rear suspension arms
Durable over sized lower suspension arms in strong composite nylon. On the lower side the downstops set-screws are mounted. The lower shock-mounting pins are secured with a small grub screw from the bottom.

Rear uprights
Composite uprights with 3 upper roll-center positions. Strong steel track-rods with L/R threading and strong balljoints to pre-set camber. Steel wheel-axles with large size bearings 8X16X5 (2) and 15x21x4 (2) with precision threaded aluminum wheel-hubs with XX offset .Flanged and serrated wheel nuts to guarantee that you will not loose a wheel nut in a race.

Rear anti-roll bar
The ball raced front anti-roll bar system, consist of a spring steel bend wire, which is guided through the diff-cases and runs in ballraced steel adapters. The wire is linked to the lower suspension arm, with a captured adjustable threaded pivotball, for very precise and low friction operation.

Shock tower rear
4.0mm thick anodized aluminum shock tower, integrated into the rear section for extra stiffness, with 3 upper positioning holes for the shocks and 5 holes for roll-center positions.

Wing mount and rear body mounts
Composite rear wing, with strong nylon adjustable rear body mounts on wide body-support bridge located far enough to the rear, to support the bodies in best way.

Captured pivot pins and balls and bolted hinge pins
All steel 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. 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.

Big bore shocks
Coated aluminum shock bodies with 4mm shock-rods. Black anodized aluminium screw on shock-tops . Pre-load adjusters with nylon spacers. Shocks use large diameter membranes and large diameter o-rings and bushings to create a supersmooth and leak-proof package. Large diameter pistons are held in place by a nut on the polished shock-rods tops. Open type spring retainer to let dirt out easy.

RCM shock springs
Short type color coded shock springs are supplied for the 1st standard set-up Springs are ground flat top and bottom, and checked individually for tension and length.

Compact gear differentials
Very compact gear differentials with very smooth metal sintered gears, and steel shaft. Perfect sealing case with special gasket and o-rings. Very durable out drive cups in steel. Hardened spring-steel diff-coupler 10T with connector running in 2 over sized bearings 8x19x6 and 13x19x4

Front cvd-set and rear dogbone style
Both front steel driveshafts are being used with CVD system. Durable steel driveshafts with hard steel pins. In the rear a dogbone type system is applied.

Strong steel transmission parts
The front and rear steel cardan shafts connect the differentials with the gearbox section.

Engine mount
Machined aluminum engine mounts for a stable engine mounting .

Coil exhaust wire and aluminum mount
The tuned pipe is securely fastened with the coil spring and aluminum holder.
Helps aid in the front to back movement of the pipe when chassis flex occurs. Helps to prevent damage to your exhaust gaskets.

3 shoe clutch
Full carbon 3 shoe clutch-set with medium type springs. Easy to assemble with light and durable anodized aluminum flywheel.

125cc fuel tank
Composite nyon fuel-tank with super sealing spring loaded shock-cap, bronze sintered clunk type filter and splash-side guard. Side features slots to mount the supplied tube-guiders. Tank mounts to chassis on longer composite posts with integrated rubber buffers to allow some movement and reduce fuel-foaming. The clunk system will allow the engine to continue running when the car is up-side-down.

Low profile air filter
Centralized air filter design to minimize cab width and height. Flexible rubber boot combined with strong nylon case to support the foam elements. Excellent dense foam air filter elements to keep your engines clean inside.

Body and Wing
Sleek, low style polycarbonate buggy body, with lines provided for cut out for engine and tank. Large rear wing in durable nylon with good down force and special shaped for best airflow over and through the wing.
