Serpent Cobra GT 3.0 1/8 4wd details

The Serpent Cobra GT is the most popular brand in GT racing and its performance is proven by many big racewins in the highly competitive race scene for GT’s in America. The Cobra GT 3.0 is the latest development stage of the Cobra GT platform, which is running successfully for over 5 years with very small changes only. Below we show the key updates to the GT to continue its strong performance and famous durability.
The Cobra GT is a combined design effort by Billy Easton and Michael Salven, in cooperation with our USA team-drivers Desoto and Morganti.

Main new features
- New XLi superlight 2-speed gearbox
- New aluminium middle bearing blocks ( holding brake and 2-speed)
- New front front and front rear aluminium suspension holders
- New Alu c-hubs in 6 degree version
- New aluminium, uprights for new rear geometry
- New alu shockabsorber risers front and rear
- New 4.5mm carbon shocktowers front and rear

Explaining the new features
New 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 accellerate faster.

New aluminium middle bearing blocks ( holding brake and 2-speed)
To hold the new 2-speed gearbox/shaft as well as the existing double brake system newly designed superlight alumnium bearingblocks are designed.

New front front and front rear aluminium suspension holders
These are designed to change the piviot pin angle, so the lower wishbones will be more straight, which geomery suits onroad racing better.

New Alu c-hubs in 6 degree version
The new alu c-hubs are needed to make maximum use of the new pivit pin / wishbone angle. CNC-machined from 7075 T6 alumnium, laser engraved and black anodised units.

New aluminium, uprights for new rear geometry
To allow a better onorad geometry we desigend these new CNC machined aluminium uprights, black anodised and laser engraved.

New alu shockabsorber risers front and rear
New alu shocktowers front and rear
The durable machined alu shock-risers front and rear allow for a more onroad aimed angle of the shockabsorber creating more overall grip and more predictable cornering. The new 4.5mm lower carbon fibre shocktowers also accomodate the new shock angles, with a choice of 5 holes for further fine-tuning.

New aluminium middle bearing blocks ( holding brake and 2-speed)

Overall features / specs


Chassisplate
Chassisplate in 3mm 7075 T6 aluminium , with machined pockets to create flex and or make 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 stiffners
Composite stiffner front and rear, to give extra stiffness, but still allow some flex as needed.

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

Radio-box
Composite radiobox 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 receiverbox. 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
Beautifully machined 7075 T6 suspension brackets in anodized, laser angraved. Pecision fit for the nylon roll center inserts and pivot balls / pins. The GT 3.0 front suspension brackets make the pivot-pin and lower arm more horizontal, which improves handling and steering.

Steeringblocks assembly
Composite steeringblocks combined with alu 6 dgr C-hubs for precise steering. Spring steel wheel-axles with large size bearings 8x18x5 and 15x21x4 with precision threaded aluminum wheel-hubs with +3 offset . Flanged wheel nuts to guarantee that you will not loose a wheel nut in a race.

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

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

Shocktower and bodymounts front / alu shock-risers
new 4.5mm thick carbon shocktower with 5 upper positioning holes for the shocks and and 6 holes for roll-center positions. 1 centrally located adjustable bodymount , and 2 forward mounted adjustable bodymounts, all with flip-tops. The durable machined alu shock-risers in front allow for a more onroad aimed angle of the shockabsorber 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

Ackermann plates
With the design of the steering bell cranks when changing the Ackermann 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 oversized lower suspension arms in strong composite nylon. On the lower side the special downstops screws are mounted. The lower shock-mounting pins are secured with a small grubscrew from the bottom.

Rear uprights assembly
New alumnium, black anodised and laser engraved uprights with 3 upper roll-center positions. Strong steel track-rods with L/R threading and strong balljoints to pre-set camber. Spring steel wheel-axles with large size bearings 8x16x5 and 13x19x4 with precision threaded aluminum wheel-hubs with +3 offset . Rubber dustcovers in the rear to protect the cvd system and keep the lubrication inside. Flanged wheel nuts to guarantee that you will not loose a wheel nut in a race.

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

Shocktower rear / alu shock-risers
New 4.5mm thick carbon shocktower, 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 alu shock-risers in the rear allow for a more onroad aimed angle of the shockabsorber creating more overall grip and more predictable cornering.

Wingmount and bodymounts rear
Composite rear wing, with strong nylon adjustable rear bodymounts 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.

Shockabsorbers big-bore 16mm
Hard Teflon coated threaded shockbodies with 4mm shock-rods. Black anodized aluminium screw on shock-tops with Serpent laser engraving. Pre-load adjusters with o-rings inside. Shocks use large diameter membrames and large diameter o-rings and bushings to create a supersmooth and leak-proof package.
