The kit includes car, clear body with mask, 4 racing wheels, rear wing, decal and full color manual. The full package to compete in high end racing, finish finals and win ! Shipping middle of march 2013.

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  kikc-up for precise landings and to protect front suspension holde rand anti-roll bar.
   
Chassis stiffners   
Composite  stiffner front and rear, to give extra stiffness, but still allow some flex as needed.   
   
Central radio / servo mount   
Composite compact radiobox which offers good space for the  steering servo and the receiver .   The whole assembly including linkages can be taken off easily and fast in one go, when cleaning the car, or doing maintenance.

Battery-cases / side-guards
The main eyecatchers are the extremely low laydown longtudinal placed battery-packs at each side of the car, being part of the side-guards, securely fastened with a flip-lid, for easy and fast battery changes. The weight low in the car and in the right position, well balanced. The Lipo holders comply with ROAR legal packs / dimensions.

Motormount:
The motor is placed in the most optimal position in the car, keeping motor-forces and transmission parts / alignment in mind.  Only one-screw  is needed to secure  the BL motor, in the nicely designed durable machined aluminium motormount. Space for additional motor-cooling available as needed.
The space for the motor allows a maximum motor-length of 70mm, which covers most widely used motors ( except for the truggy / monstertruck motors).
    
Suspension brackets   
Beautifully machined  7075 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 10 dgr C-hubs  for precise steering.  Spring steel wheel-axles with large size bearings    and larger inner     with precision threaded aluminum wheel-hubs with offset  . Flanged and serrated 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 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   
   
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..

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.

The ballraced front anti-roll bar  system, consist of a spring steel bend wire, which is guided through the rear wingmount 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
