Serpent Cobra GT 3.1 Nitro

Serpent Cobra GT 3.1 Nitro
Serpent announces the 3.1 version update for the Cobra GT nitro! Features include the addition of the SRX8 brake set and aluminum center brackets, new 4.5mm carbon fiber shock towers, new aluminum shock extensions, SRX8 style shock stays, silver front and black rear springs, 2.3 front and 2.7 rear sway bars and spiral type diff gears. Check out the rest of the details below.

Chassis
Chassis plate in 3mm 7075 T6 aluminum, with machined pockets to create flex and or make it lighter. Kick-up angle on front according the race-rules. Countersunk holes. Slots to locate the front and rear suspension mount 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.

Central disk brake system SRX8
Very low and centrally placed brake system for low center of gravity with steel brake disks, combined with steel brake pads with glued on high friction brake material

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.

Suspension brackets
beautifully machined 7075 T6 suspension brackets in anodized, laser engraved. Precision fit for the nylon roll centre 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.

Steering blocks assembly
Aluminum steering blocks combined with aluminum 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 lose a wheel nut in a race.

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.

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 adaptors. 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
new 4.5mm thick carbon shock tower with 5 upper positioning holes for the shocks and and 6 holes for roll-centre 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

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 down stops screws are mounted. The lower shock-mounting pins are secured with a small grub screw from the bottom.

Rear uprights assembly
new aluminum, black anodized and laser engraved uprights with 3 upper roll-center positions. Strong steel track-rods with L/R threading and strong ball joints 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 lose 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 ball raced steel adaptors. 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 rear / alu 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.

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 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.

Front and rear cvd-sets
both front and rear captured drive shafts are being used with CVD system. Durable yet light spring steel engraved drive shafts with hard steel pins.

Spring steel transmission parts
the front and rear thin but strong spring steel cardan shafts connect the differentials with the gearbox section.

Engine mount
Machined 7075 T6 aluminum engine mounts with side cooling fins.

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

SL8 XLi 2-speed gearbox
SL8 gearbox comes straight from the Serpent 977-EVO 1/8 scale on road car. Very light and compact design. Centrifugal spring loaded shoe system with small aluminum bell and flange with one-way bearing. Durable composite 2-speed gears with smaller pitch.

2-speed clutch-housing with screw-on gears
Strong steel clutch-housing with precision machined threading, with hard coated aluminum screw on gears with smaller pitch.

4-shoe clutch
2 carbon and 2 aluminum shoe 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.
