The hardcoated lightweight 2mm 7075 T6 aluminium chassis has the right flex combined with the composite side-guards / chassis stiffeners and center spline. All holes are countersunk to have a fully flat bottom surface. Holes are centered and symmetrical for even flex.

CHASSIS stiffener

In the rear the SDX4 features a carbon fibre chassis stiffener which is clamped between the rr fr suspension bracket and the bulkhead and extends to the center. The brace has 5 optional holes to choose the stiffness by placing the small stiffener pole and screw or even adding more poles/screws.
The system influences rear end flex and is set depending on grip levels and driving style.

Battery and stays

The SDX4 car accepts a shorty in standard trim, but you can also mounts saddle packs as needed. The battery is kept in place by an easy to use composite battery-cover with a twistnut on one side.


The center of the car allows plenty of space to mount the most popular speedo and receivers, as well as the transponder. The car also allows enough space to enable nice routing of your cables. On the side of the slipper the SDx4 offers 2 special cable guiders.

Default is shorty battery rear right, motor rear left, speedo/RX front left , servo front right

Motor and holder more to the center, moves weight bias to the front

Servo mount

The servo is mounted in the car with a stand made from alu and carbon parts, and is mounted on the centerline in the car, to keep even flex. Various spacers and horns are included to suit the most popular servo brands. An optional part also allows the servo to be moved under the steering plate and driveshaft. Maximum choice of layouts.


The SDX4 uses lightweight springsteel univeral driveshafts front and rear and central universals too.

Gear-diffs and cases

The 2 compact oil-filled gear differentials front and rear. These super smooth units are light and compact and very durable. The differentials are also very easy to build and are very low maintenance.
Both the outer differential cases ( front and rear) are clamped between the aluminium bulkheads and require no other fasteners at all. Super simple and fast for maintenance.

Differential main gear and bevel gear

The precision machined straight cut differential main gear and bevel gear are made in hardened springsteel for smooth operation.

Balljoints / trackrods

New style and material balljoints for smooth suspensions and steering. The outer steering balljoints are angled to clear all rims/tyres . The trackrods and camberlinks are made in thin but durable springsteel with L/R threading for asy adjustment.


Serpent hard coated shock bodies and composite shock tops for super smooth operation and durability. 3.2mm shafts with new pre-oiled X-ring package and molded pistons. The shocks can be used either emulsion or membrane configuration. The shock springs have grounded ends, checked and matched for perfect equal operation. Ride height can be easy set with the threaded collars which have o-rings inside to stay in position.

Shock towers

Very durable 4mm thick carbon fiber front and rear shock towers with 3 positions for shock angle. For roll center adjustment the front bracket features 6 holes to chose camberlink positions. 3 inner and 3 outer. The rear one has 8, 4 inner and 4 outer.

Slipper clutch

This light slipper-clutch unit, is a spring loaded 3 pad version, allows to control the power distribution.


The fully ball raced angled dual axis steering system with integrated servo saver function, offers an almost perfect Ackermann effect. Ackermann can be set with small plates which mount to the steering arms and the black cotaed aluminium steeringbrace has 2 holes to choose from. The servosaver has a pre-load nut to easily set the desired tension.
The steeringsystem is mounted on a carbon fibre u-bracket which also connects the front left and right sides and acts as a stiffener.

Steering blocks and c-hubs

The lightweight composite steeringblocks are combined with aluminium 7075 T6 c-hubs. The c-hubs has 2 positions for rollcenter, and can be further finetuned by using more or less shims. The c-hubs are 5 degree, other optional ones are 0 and 3 degree.

Front suspension

Strong composite lower suspension arms with mounting spots for the pivotball activated anti-roll bar. The arms are a closed type design for aero effect, rigidity and clean looks. On the upper side optional carbon inserts can be applied in case harder arms are needed for handling. Composite insertplates are standard. The front arms have 2 shockangle positions.

Rear suspension

Strong composite lower suspension arms with mounting spots for the pivotball activated anti-roll bar. The arms are a closed type design for aero effect, rigidity and clean looks. On the upper side optional carbon inserts can be applied in case harder arms are needed for handling. Composite insertplates are standard.
The rear arms have 2 shock mounting positions on each side front and rear. The front and rear shockmounting positons are different and the arms can be used on both sides of the car, so you have 4 shock angle positions to choose from.
The rear arms allow to mount the shocks also in the rear of the car.

Suspension arms pivot balls

Instead of inner pivot pins the SDX4 uses small pivotballs which thread inside the arm. The suspension brackets are machined to adapt the pivotballs and create a low friction, no binding suspension. By turning the pivotballs in or out you can set the optimal play between the front and rear bracket.

Suspension brackets

Hard coated aluminum suspension brackets fr fr and fr rr. Small but effective composite front bumper to protect the front end. The angled front built in kick up allows for smoother landings.
The rear rear suspension bracket can be used standard with o-degree or upside down as 3-degree anti-squat.


The strong front diff case assembly based on 2 durable 7075 T6 bulkheads is a very strong affair to mount the diff-housings, front shock tower and chassis too. Its also features the holders for the ballraced anti-rollbarmounts.

Anti-roll bar

Both the front and rear arms and bulkheads allow mounting the ball-raced anti-roll bars. The wire type anti-roll bars are lasered for easy indentification. The wire connect to the arms with the proven friction free supersmooth pivotball system. Its very easy to access and change the anti-roll bars as needed.

Motor mount

The motor is mounted securely to the thick 3mm cnc machined 7075 T6 alu motor plate. The motor is mounted to the sliderplate, which is then easily slotted in position.

Center drive holders

The slipper clutch unit is hold in place by the motormount bracket and a H shaped lightened 7075 T6 aluminium holder topped by a carbon connector plate that also holds the cable guiders in place.
The slipper can also be replaced by a geardiff in the center. Its supereasy to access the slipper or optional central geardiff.


The lightened 7075 T6 aluminium uprights are same left and right and feature 3 camberlink positions.


The front and rear wheel hex are 12mm industry standard size. The hexes are clamp type and anodised to last. Flanged wheelnuts are included to keep the wheels in place.

Body mounts

The strong composite body mounts are easily located in case used. As alternative velcro can be added to the side of the chassis stiffeners/side bars.


Top quality clear polycarbonate is used for the Spyder SRX4 buggybody . The nicely shaped body has flat sides and roof for extra downforce and great handling. It leaves enough space for electronics and cooling finds as needed. The body closely follows the chassis shape, so less debris can enter the car. The body comes with a white precut masking sheet.

Rear wing and wing holder

The strong clear polycarbonate wing is mounted to the nylon rear wing holder.

Manual / setup sheet / decals

The Spyder SDX4 comes with a PDF style full color manual on a Serpent USB stick which shows the assembly process in steps following the packed bags. The manual also includes the exploded views and a ref-guide to make it easy to find the part numbers you may need of spares and optional parts.

Interview 4wd buggy EC Champ 2016 Joern Neumann - Germany

Congratulations for winning the 2016 EFRA 1/10 4wd title after already becoming 2016 Vice Champion in 2wd.

Q: Did you expect such superb result before the race started ?
A: I knew my new Serpent SRX2 proto is good and the new SDX 4wd shaftdrive car too , but it is always different at a race than testing. After first couple runs I was pretty confident to get good results.
Q: Did you test on the track before or similar surfaces prior to the EC race ?
A: Gerd and I tested on the track a few months before the Euros, but it was completely different than at the EC, as the layout was changed after the test.
Q: Which car did you use for the 4wd EC race and is it close to ready to sell ?
A: I used the new Serpent SDX4 shaftdrive 4WD in almost final pre production version. Its expected it to start selling end December 2016.
Q: What are the specific advantages at this EC using this Spyder SDX4 car, designed by your friend Gerd Strenge ?
A: You can run different electronic layouts to choose the best for each track conditions. Also it is very easy to work on the car. I think the drivers will like it a lot.
Q: Which radio, speedo, motor and batteries did you use and did all work well ?
A: All my Team Orion electronics ran flawless all week. I used the R10.1 ESC, VST2 5.5T motor and 5500mAh Saddle Pack Lipo┬┤s. Topped by a K-Power DHV822 Servo.
Q: What were the main changes made to the SDX4 car or set-up to get to the final set-up ?
A: We didnt have to change much as the car worked from early practice runs. Just very small changes to adapt to the track and temperature changes.
What do you like to say to your fans ?
Quote: Thanks for all the FB and whatsapp messages at the Euros !!! Great support.
