> Description

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   !

Key changes  for the 2.0 version
-   Improved rear geometry with wider rear lower arms, new uprights and new shock position
-   Longer rear shocks and higher rear carbon shocktower for more travel
-   Shocks moved to the back, to make access and adjusting easier, and make rear end more stabile and responsive
-   rear wing with integrated holders for the ballraced rear anti-roll bar
-   lexan mud-guards to mount on lower rear arms
-   nylon mud-scrapers mount on the rear uprights
-   improved differential gears - as already in the Be version
-   larger bearings in steeringblocks and uprights 8X16X5 (2) and 15x21x4 (2),
-   transmission using larger bearings 8x19x6 and 13x19x4 and new couplers for extra durability

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.

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.
