Serpent Cobra SRX8-E 1_8 4wd Electric Buggy (6)

Serpent introduces the new 1/8 scale E-Buggy, Cobra SRX8-E.

The car is designed by Billy Easton in the USA and is based on the 2016 released Cobra SRX8 gas-powered buggy and shares the whole front and rear suspension system, shocks and gear diffs.

The Cobra SRX8-E offers some unique features that make it really special. The SRX8-E comes standard in block or brick pack layout as this is the most commonly used one. However the SRX8-E can be changed in very little time to the optional saddle pack lay out, using the same chassis, motor holder and center diff holder.

Other main specs:

Hard coated 4mm chassis 7075 T6 aluminum , flat style sides, with kick up
Block type layout with long front center shaft and short rear one
Easy access receiver box and speedo/servo holder
Smart integrated design chassis stiffeners
Machined aluminum 15 dgr C-hubs, steering blocks, uprights, shock towers, one-screw motor holder and center diff brackets, as well as suspension mounts
Hard coated Big bore shocks 16mm ( emulsion/membrane ) with high end racing springs and hard coated aluminum shock standoffs
Durable suspension arms with top and bottom mounted inserts ( for optional carbon inserts)\Coated aluminum suspension holders with a variety of possible inserts
Spring steel pivot pins rotate in pivot balls for minimal friction
Angled steering system with adjustable Ackermann and integrated effective servo saver
3 large volume durable gear differentials with foam compensator inserts
Easy access differential cases
Spring steel transmission parts, cvd style drive shafts and rear center dog bones,
rubber dust covers on front and rear cvd’s
Black coated 7075 T6 aluminum front center shaft
Ball raced front and rear anti-roll bars with Serpent pivot ball linkage system on the arms
Top quality NSK ball bearings in main areas
ightweight hard coated aluminum track and steering rods
Low profile medium downforce body shell and polycarbonate mudguards
Large high downforce molded straight type rear wing and strong monotype adjustable wing mount

The optional upgrade set to the saddle pack layout consists of the 2 light battery trays/sideguards to be used with touch-belts or optional carbon top decks, composite chassis stiffeners and the 2 long center steel shafts. The receiver box moves from the rear section to the front center. The smart layout and use of universal parts makes changing from block to saddle layout a quick and easy as chassis and motor holder are the same.

The body for the SRX8-E buggy is a medium downforce design with steep angle front windshield, wide angled sides and stepped rear side to guide the air onto the rear section and rear wing. The body leaves plenty space to mount electronics and fans as needed. Made in top quality, clear polycarbonate and comes with a practical masking sheet and a separate Serpent and Cobra SRX8 logo decal sheet.

The sturdy composite chassis stiffener in the rear doubles as gear diff-cover, and an additional stiffener in the center connects the front and rear end. For more flex that one can be removed, as also the battery-box already adds stiffness in that area. The front stiffener is integrated in the servo/speedo holder and connects to the top-bracket.

The lightweight long center shaft is made in 7075 T6 aluminum, black coated and the short rear one in Serpent spring steel, dog bone style. Combined with very durable and lightened spring steel driveshaft adaptors.

Composite block style battery tray with self-adhesive bottom foam padding and side foams for battery protection. 3 pieces OneTouch straps are included to fasten the Lipo in position.

The left side-guard on the block layout features and user friendly rail and top cover to nicely guide and protect the longer receiver cable.

The completely closed SRX8-E chassis is made in 4mm 7075 T6 aluminum and has flat but chamfered sides, countersunk holes and a kick up. Hard coated for durability. The same chassis is used for the block and saddle layout. The chassis stiffness comes from the smart design integrated molded center stiffeners as well as the strong and durable sideguards. This package creates the optimal flex characteristics needed.

The composite receiver box with cover bolts onto the chassis and fits all modern receivers, even ones with build in antennas. The receiver box can also be mounted in the front center section, which is normally used in the saddle configuration only. A nice carbon looks decal on the top cover.

The combined speedo holder / servo holder is a durable unit which will fit all most popular speedo’s and servo’s easily. The whole unit with mounted gear can be easily taken out for maintenance or cleaning.

Strong grey coated aluminum machined center diff holder on one side and the other side is integrated in the motor holder featuring a slide, which can be turned around when used for the saddle layout.

The light machined aluminum motor holder uses a slider which is secured with only one screw, a system which Serpent applied from the very beginning in the 811-Be and 977-e already. The slider plate is a little bit thicker to mount the motor and still clear the mount when sliding. Both slider and mount come grey anodized. In case of using the saddle layout, the same motor mount is used, just the center insert is turned around 180 degrees. So a very smart, integrated and versatile design.

The SRX-E comes as a very complete and high end race-buggy with many nice 7075 T6 machined aluminum parts like C-hubs, center front shaft, ,steering blocks, uprights, shock towers, chassis, one-screw motor holder and center diff brackets, as well as suspension mounts.

Motor holder

Centre diff holder

Strong grey coated aluminum machined center diff holder on one side and the other side is integrated in the motor holder featuring a slide, which can be turned around when used for the saddle layout.

Speedo/servo holder/front stiffener

Receiver box

Chassis plate

Sideguards

The left side-guard on the block layout features and user friendly rail and top cover to nicely guide and protect the longer receiver cable. The sideguards keep debris out and protects against side-impact.

Battery-tray

Composite block style battery tray with self-adhesive bottom foam padding and side foams for battery protection. 3 pieces OneTouch straps are included to fasten the Lipo in position.

Centre shaft

Chassis stiffeners

The sturdy composite chassis stiffener in the rear doubles as-cover, and an additional stiffener in the center connects the front and rear end. For more flex that one can be removed, as also the battery-box already adds stiffness in that area. The front stiffener is integrated in the servo/speedo holder and connects to the top-bracket.

Steering system – servo saver

The dual axis steering system with integrated servo saver is mounted under an angle for less bump steer and a more direct steering feel. The axles are made in lightweight aluminum. The bell crank accepts a bearing raced crossbar with zero slop. It’s designed with the optimal Ackermann to increase the cars drivability.

Servo saver

It incorporates a helix in order to guarantee the proper operating of the servo saver assembly. The servo saver spring is protected by a dense foam cover, to keep debris out. The spring pre-tension clamp nut can be locked in place to avoid turning loose. Ackermann changes can be made easily.

Differential cases

The differential front and rear can be removed after taking out only 4 screws and removing the anti-roll bars, super-easy! The strong molded differential cases which contain the differential and support the shock towers.

Gear-Differentials

The diff-gear cases are bigger in volume to allow more diff oil. The diff now has cavities designed specifically for closed cell foam. This foam will compensate for expansion of the oil, which will allow us to fill the diffs more full, keeping the gears fully engulfed in oil. The cavity where the gears rest has also been redesigned so that there is not low pressure zones outside of the gears. This will keep more oil on the gears even when spinning at high rpms. This in turn will keep the diff more consistent at low and high speeds as well as hot or cold.

Gears 28 / 14 / 44: The hard metal 28T and 14T satellite gears have a larger overall diameter, to make sure they are more in oil, making the diff more consistent, smoother and stronger. The steel 44T ring gear is lighter and has a perfect match with the new 28T gear.

Wheel axels / hex / boots

The durable Serpent spring steel wheel axles are captured CVD style and have rubber boots to protect the system and bearings against dirt and dust, so it will all last longer. The wheel hex is a durable hard aluminum version which fits all popular wheels very well. The pins in use are 3mm ones to increase durability.

Steering blocks aluminum

The steering blocks are made in 7075 T6 aluminum and are anodized in black. These steering blocks have been designed to allow you to change the Ackermann at the steering spindle as well as give us the optimal scrub offset in conjunction with the caster block. The bushings press into the blocks and reduce any unwanted play.

C-hubs aluminum

The 15 dgr c-hubs are made in 7075 T6 aluminum and are anodized in black. These open style very durable units allow enough space to allow for the maximum steering angle and allow space to mount the rubber dust protectors on the CVD system. As optional we offer 13, 17 and 19 dgr c-hubs too.

Uprights aluminum

The uprights are made of 7075 T6 aluminum and are universal ones to be use left and right . The new uprights have the roll center adjustment in them with small inserts. Set screws are used to tighten down on the hinge pin to eliminate any unwanted play. In the bottom part 2 threaded holes are made to allow for mounting the optional brass weights of 15 gr each for rough conditions.

Wishbones, composite

Very durable and long molded wishbones front and rear. The composite is chosen to have enough flex as needed. The design has pockets in the top and bottom part of each arm to mount the standard molded insert plates, or the optional carbon fiber ones. In that way you can choose the right arm flex for each condition. Even different or no inserts front or rear and mixing molded and carbon inserts is possible. The molded inserts will stiffen the arms only a little, but keeps them cleaner. The carbon ones, or mixed with molded ones will stiffen the arms a lot. Many options to try and apply. The front wishbones have 2 holes for shock-mounting, the rear ones even 3.

Mudguards

The mudguards are offered in lightweight transparent polycarbonate and can be left clear, be painted or skinned as preferred.

Suspension brackets

The suspension brackets are CNC machined in 7075 T6 aluminum and grey anodized. They key into the chassis for perfect fit. The brackets have precision machined pockets to use a full range of molded inserts to change the set-up.

Anti-roll bars

The anti-roll bar system is the best around. Precision made wire runs in ball raced adaptors on the front and rear diff case-plates. Super free and stabile. The wire connects to a ballpoint which is fitted with a pivot ball to the wishbone. The works!

Shock Towers

The front and rear shock towers are durable hard anodized 4.5mm 7075 T6 aluminum units, CNC machined. 4 positons each for shock-angle and 6 for roll center.

Shocks

Big bore shock with hard coated dual-system caps and hard coated bodies. Durable polished steel 3.5mm rods are used with hard anodized caps and threaded shock-bodies. A new seal pack consists of machined bushings and new x-rings and is kept in place with a small inside clip. The shock pistons are machined delrin units for best performance. The shock -tops in the kit can be used membrane style or emulsion type with seals.

Shock Springs

Race shock spring which are hand-selected and paired. The shock springs are grinded flat for perfect operation.

Wing rear black

The new flat type rear wing is a very effective high downforce unit with large side wings

Wing holder rear

The rear wing holder is a super durable and light one piece molded unit. The holder has 4 different angle spacer to choose from .

Body

A new Avenger style body is developed for the SRX8E with medium level downforce. Cab-forward style body with small fin on the roof for stability. Nice flowing sides with small rear upward fins for rear downforce. Top quality polycarbonate. The body has nice trim lines for easy cutting. Same for the body holes. A masking sheet is included to assist with paintjob preps.

Body mounts

This rear body mount has a rubber cushion in it. It allows the body mount to rotate front to rear in an impact or crash. This saves the body from breaking or tearing. The front one is a fixed type and is easy accessible.

Manual
New style manual in landscape orientation to have more space to explain all, and have correct layout for screen use as well. Full color version with additional detailed views and notes, and also showing the hardware in real size on each page in full color PDF style. Its available online and also on a nice small USB stick with Serpent logo in the kit.

Decals

In the kit comes 1 Serpent logo sheet and 1 SRX8 Sheet, as thin strong decals, pre-cut logo’s

Oils and grease

The kit includes shock oil, diff oil and grease for the joints.

Bearings

The SRX8E uses top quality NSK bearings in the more critical area’s
