Serpent Cobra 811B E Buggy 2.1

Serpent Cobra 811B E Buggy 2.1Serpent announces an updated version of the Cobra E Buggy! The Cobra 811B E 2.1 features a number of new updates including new uprights, axles, 98mm driveshafts, axle boots, aluminum c-hubs and 2.3mm anti-roll bars. Check out the rest of the story and tons of pictures of the new electric Cobra buggy after the break.

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 top rated, 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.

Chassis
Chassis plate in 3mm 7075 T6 aluminum , with machined pockets to create flex make lighter. Kick-up angle on front for stable 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 stiffeners
Composite stiffener front and rear, to give extra stiffness, but still allow some flex as needed.

Central radio / servo mount
Composite compact radio box 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 eye catchers are the extremely low lay down longitudinal 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 aluminum motor mount. 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.

Suspension brackets
Beautifully machined 7075 T6 suspension brackets in anodized, laser engraved. Precision fit for the nylon roll center inserts and pivot balls / pins.

Steering blocks assembly
Composite steering blocks combined with 14 degree aluminum 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.

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 ball raced front anti-roll bar system, consist of a spring steel bend wire, which is guided through the diff-cases and runs in ball raced steel adapters. The wire is linked to the lower suspension arm, with a captured adjustable threaded pivot ball, for very precise and low friction operation and easy tuning.

Shock tower and body mounts front
4.5mm thick carbon shock tower with 5 upper positioning holes for the shocks and and 6 holes for roll-center positions. 1 centrally located adjustable body mount , and 2 forward mounted adjustable body mounts, 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 over sized lower suspension arms in strong composite nylon. On the lower side the special down stops screws are mounted. The lower shock-mounting pins are secured with a small grub screw from the bottom.

Mud-guards
Super light 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 ball joints 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.

Rear anti-roll bar
The ball raced front anti-roll bar system, consist of a spring steel bend wire, which is guided through the rear wing mount and runs in ball raced steel adapters. The wire is linked to the lower suspension arm, with a captured adjustable threaded pivot ball, for very precise and low friction operation.

Shock tower rear
4.5mm thick carbon shock tower, integrated into the rear section for extra stiffness, with 5 upper positioning holes for the shocks and 6 holes for roll-center positions.

Wing mount and body mounts rear
Composite rear wing, with strong nylon adjustable rear body mounts on wide body-support bridge located far enough to the rear, to support the bodies in best way.

Captured pivot pins and balls
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 shock bodies with 4mm shock-rods. Hard anodized aluminum screw on shock-tops with Serpent laser engraving. Pre-load adjusters with o-rings inside. Shocks use large diameter membranes and large diameter o-rings and bushings to create a super smooth 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
Color coded progressive shock springs are supplied for the 1st standard set-up and all springs are grinded flat top and bottom, and checked individually for tension and length and matched.

Compact gear differentials
Very compact gear differentials with very smooth metal sintered gears, and steel shaft. Perfect sealing case with special gasket and o-rings. Very light and durable outdrive cups in spring-steel. Hardened spring-steel diff-coupler 13T with connector running in 2 oversized bearings The Cobra-E uses a 13T / 44T combo gearing. 46T central diff gear. This drive ratio will provide amazing acceleration combined with the low vehicle weight.

Front and rear cvd-sets
Both front and rear captured driveshafts are being used with CVD system. Durable yet light spring steel engraved driveshafts with hard steel pins.

Spring steel transmission parts
The front and rear thin but strong spring steel cardan shafts connect the differentials.
