Introduction

The Serpent Cobra Buggy 2.1 is a result of continuous development  and intensive cooperation with the key team-drivers.

The changes for the 2.1 version are not very big, but very important to make you go around the track easier and faster.  The longer chassis combined with the 14 degree castorblocks offer a really big difference in overall handling.

Serpent Cobra 811 Buggy 2.1 1/8 4wd

Cobra Buggy 2.1 main new features:
-   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.  

The Cobra buggy 2.1 will have an additional sheet to show the new items and assembly.


Chassisplate   
4mm longer hard anodised 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  kikc-up for precise landings and to protect front suspension holder and anti-roll bar.
   
Chassis stiffners   
Aluminium longer rear stiffner, and composite  front stiffner, to give extra stiffness, but still allow some flex as needed.   
   
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  7065 T6  suspension brackets in anodized, laser angraved.  Precision fit for the nylon roll center inserts  and pivot balls / pins.    
   
Steeringblocks 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.   
   
Shocktower 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   
   
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 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  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 and serrated wheel nuts to guarantee that you will not loose a wheel nut in a race.   

Mud scrapers
Composite mud scrapers which mount to the new uprights, and will keep the inside of your wheel cleaner in case of muddy  conditons.
   
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    
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.    
   
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.
