Serpent introduces the updated version of the Cobra GT. The Cobra GT is a very popular choice in this class with superb performance and being known as a very durable car too. Time to add some extra refinement.

The Cobra GT is sensitive on the shock-angle and position both front and rear and that have been fine-tuned even more. The new version aluminum shock extensions in the front and rear are a bit longer than before, as testing showed a good increase in handling. The new super-durable carbon fibre shocktowers and new upper hardcoated alu shockmounts make things perfect.

The brake of the new Serpent SRX8 1/8 buggy bolts straight into the Cobra GT and is more effective with its steel diskbrakes and pre-glued brake pads. A smoother brake feel, less fading if any and easy to maintain.

The Cobra GT 3.1 version gets the most popular shock springs as standard, and same goes for the ball raced anti-roll bars and shock and diff oils.

Team Serpent

New aluminum shock absorber riser’s front and rear The durable machined aluminum shock-risers front and rear allow for a more progressive angle of the shock absorber creating more overall grip and more predictable cornering.

New shock towers front and rear
The new 4.5mm lower carbon fiber shock towers also accommodate the new shock angles, with a choice of 5 holes for further fine-tuning, and 9 choices for roll center position on the camber-bracket/tower.

New type hard coated aluminum shock mounts front and rear Lightweight but durable hardcoated alumnium 7075 T6 threaded mounts. Easy to mount.

New SRX8 brake system
The brake system comes from the SRX8 buggy and features steel brake disk and brake pads with glued on high friction brake material

XLi superlight 2-speed gearbox
The XLi gearbox comes from the Viper 977-Evo kit and is well proven for performance and durability, as well as ease of setting. The lower inertia will make you accelerate faster.

Aluminum middle bearing blocks
To hold the 2-speed gearbox/shaft as well as the SRX8 double brake system superlight aluminum bearing blocks are designed.

Aluminum c-hubs in 6 degree version
The new aluminum c-hubs are needed to make maximum use of the new pivot pin / wishbone angle. CNC-machined from 7075 T6 aluminum, laser engraved and black anodized units.

Aluminum, uprights for new rear geometry
To allow a better on road geometry we designed these new CNC machined aluminum uprights, black anodized and laser engraved.

Chassis plate

Chassis plate in 3mm 7075 T6 aluminum, with machined pockets to create flex and or make it lighter. Kick-up angle on front as need due to the race-rules. Countersunk holes. Slots to locate the front and rear suspension mounts precisely. Angled sides to increase stiffness. Open pockets to access flywheel and 2-speed gearbox. Laser engraved Cobra GT logo.

Bumper

Captured foam bumper set, with wide foam bumper and strong upper and lower bumper-plate.

Chassis stiffeners

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

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 servos. 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 run very clean and tight and are easy to access to modify settings.

Radio-box

The newly developed front Flow aero type bumper is a very durable unit, which as extra feature offers removable inserts. Its very easy and quick to change aerodynamic characteristic in a matter of seconds. By just removing or adding the inserts to increase or decrease steering / turn-in. The ribs in the bottom guide the air below the chassis / body.
The durable aluminium front bodyposts are excentric , to allow moving the body to front or back a few mm to optimize steering / downforce.

Suspension brackets

Beautifully machined 7075 T6 suspension brackets in anodized, laser engraved. Precision fit for the nylon roll center inserts and pivot balls / pins. The GT 3.1 front suspension brackets make the pivot-pin and lower arm more horizontal, which improves handling and steering.

GALLERY

Front suspension

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

Shock tower and body mount front / aluminum shock-risers
New 4.5mm thick carbon shock tower with 5 upper positioning holes for the shocks and 6 holes for roll-center positions. 1 centrally located adjustable body mount, and 2 forward mounted adjustable body mounts, all with flip-tops. The durable machined aluminum shock-risers in front allow for a more on road aimed angle of the shock absorber creating more overall grip and more predictable cornering.

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

Shock tower rear / aluminum shock-risers
New 4.5mm thick carbon shock tower, integrated into the rear section for extra stiffness, with 5 upper positioning holes for the shocks and 6 holes for roll-center positions. The durable machined aluminum shock-risers in the rear allow for a more on road aimed angle of the shock absorber creating more overall grip and more predictable cornering.

Wing mount and body mounts rear
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 spring-steel hinge pins are either captured or bolted in place and made in spring-steel quality. 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.

Shock absorbers big-bore 16mm
Hard Teflon coated threaded shock bodies with 4mm shock-rods. Black anodized aluminum screw on shock-tops with Serpent laser engraving. Pre-load adjusters with O-rings inside. Shocks use large diameter membranes and large diameter O-rings and bushings to create a super smooth 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.

Very compact gear differentials with very smooth metal sintered gears, and steel shaft. Perfect sealing case with special gasket and O-rings. Very light and durable outdrive cups in spring-steel. Hardened spring-steel diff-coupler 13T with connector running in 2 oversized bearings 8x19x6 and ballbearing-13x19x4.

4-shoe clutch
Full carbon 4 shoes clutch-set with medium type springs. Easy to assemble with light and durable anodized aluminum flywheel.

150cc fuel tank

Composite nylon 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.

Needed to complete the car:

Radio and receiver
Rx battery pack
Engine and pipe system
Foam on road air filter or off-road type
Wheels and tires
Body and wing
