Serpent Cobra GP Buggy B 2.2  1/8 scale 4wd

The Serpent Cobra Buggy 2.2 is a result of continuous development  and intensive cooperation with the key team-drivers.

Key new features
Upright buggy 1/8 V2 (2)
Wheelaxle buggy v2 (2)
Driveshaft buggy 98mm (2)
Wheel-axle boot rubber (2)
Antiroll bar front 2.3mm
plus 4 chassis:  the hard anodised chassis is 4mm longer in the rear, creating a more stable rear end, especially better on tracks with short bumps and rough surface.  The great handling on smooth, flat
surfaces remains !
longer alu rear brace: the longer alu brace also helps to make the rear end more stable.  The shorter nylon or alu version can also still be
fitted.
longer rear central shaft:  to suit the longer chassis a longer rear
central shaft is needed (which is actually the same as the one used in Cobra buggy 1.0 )
hard coated shockcaps:  the hardcoated aluminium shockcaps can
withstand the rigors of crashes better
aluminium 14 dgr casterblocks  The Cobra buggy has a lot of steering already which makes it  turn very fast. The 14 degree caster blocks
help to smoothen steering out a bit, still lot of steering , but easier,
less direct, creating a more stable front end.

INTRODUCTION:

This new development for  Cobra buggy is realized after another full year of racing across the globe, listening to feedback from many (team)-drivers and dedicated testing on many different surfaces.  The feedback from the drivers on the Cobra Buggy in general is very good, the durability is rated as best in the market, the shocks are toprated, and the diffs and drivetrain with new gears and larger bearings can now withstand any rigors and will last and last !   According to same drivers a more responsive rear end, combined with a bit more steering would bring the Cobra on the highest level. 

Well, the changes as below accomplish just that, and for sure we will continue the superb quality on the kit overall   !

CHASSISPLATE:

Chassisplate in  3mm  7075 T6 aluminium , with machined pockets to create flex  make lighter.  Kick-up angle on front  for stabile landings.  Countersunk holes.   Slots to locate the  front and rear suspension mounts precisely.  Angled sides to increase stiffness.  Laser engraved Cobra logo.

BUMPER:

Aligned with chassis  kick-up for precise landings and to protect front suspension holder and anti-roll bar.

CHASSIS STIFFNERS:                                

CENTRAL RADIO / SERVO MOUNT:

Composite radiobox which offers good space for the  steering and throttle -servo, the receiver and  rx battery.   The whole assembly including linkages can be taken off easily and fast in one go, when cleaning the car, or doing maintenance. One extra post is added close to the servo for stability.

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 angraved.  Precision fit for the nylon roll center inserts  and pivot balls / pins.

STEERING BLOCKS ASSEMBLY:

Composite steeringblocks combined with 14 dgr black anodised aluminium C-hubs  for precise steering. Composite 10 and 12 dgr c-hubs are also included. Spring steel wheel-axles with large size bearings and larger inner with precision threaded aluminum wheel-hubs with offset. Flanged and serrated wheel nuts. 

FRONT SUSPENSION:

Durable oversized  lower suspension arms in strong composite nylon. On the lower side the special shaped 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 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 and easy tuning.

SHOCK TOWER AND BODYMOUNTS FRONT:

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.

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 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 longer 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.

MUD-GUARDS:

Superlight polycarbonate mud guards  mount to the new lower suspension arms, and will keep dirt away from your anti-roll bars transmission and wheels.

REAR UPRIGHTS V2 ASSEMBLY:

Composite 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  and larger inner  ones  with precision threaded aluminum wheel-hubs with 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.

CAPTURED PIVOT PINS, 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 RCM BIG-BORE 16MM:

Hard Teflon coated threaded  shockbodies with 4mm shock-rods.  Hard 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.  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. The shock-shafts are protected by rubber boots.

RCM SHOCK SPRINGS:

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