Serpent Cobra Be 2.1 4WD race buggy Kit 1/8 scale, electric powered |
|||
 |
State of the art design of the central section, with advanced integrated standing servo, receiver, speedo bracket, ingenious motor-bracket and lay-down Lipo-pack configuration with practical lid-system. Extremely narrow and low design, optimised for overall weight balance. Low body-design and low rear wing / wingmount. The changes for the 2.1 version are not big, but very important to make you go around the track easier and faster. Key new features |
||
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: 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.  |
MOTOR MOUNT: 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. |
STEERING BLOCKS ASSEMBLY: Composite steeringblocks combined with 14 dgr aluminium C-hubs for precise steering. 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. |

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 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 longer oversized lower suspension arms in strong composite nylon. On the lower side the special downstops screws are mounted.
