Meet the new Serpent SDX4 1/10th scale 4wd competition RC buggy! Features include a shaft driven 4wd system with three gear differentials and slipper clutch, a hard anodized 2mm aluminum chassis, ball bearing supported front and rear sway bars, aero wishbones with inserts and pivot balls, tons of carbon fiber and aluminum parts and much more! Check out the pictures and the rest of the details on the Serpent SDX4 buggy after the jump!
Strong composite lower suspension arms with mounting spots for the pivotball activated anti-roll bar. The Serpent SDX4 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 insert plates are standard. The rear arms have 2 shock mounting positions on each side front and rear. The front and rear shock mounting positions are different and the arms can be used on both sides of the car, so you have 4 shock angle positions to choose form. 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.
Hard coated aluminum suspension brackets fr fr and fr rr. Small but effective composite front bumper to protect the front end. The Serpent SDX4 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 SDX4 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-rollbar mounts.
Both the Serpent SDX4 front and rear arms and bulkheads allow mounting the ball-raced anti-roll bars. The wire type anti-roll bars are lasered for easy identification. The wire connect to the arms with the proven friction free super smooth pivotball system. Its very easy to access and change the anti-roll bars as needed.
The Serpent SDX4 motor is mounted securely to the thick 3mm cnc machined 7075 T6 alu motor plate. The motor is mounted to the slider plate, which is then easily slotted in position.
Center drive holders
The SDX4 slipper clutch unit is hold in place by the motor mount bracket and a H shaped lightened 7075 T6 aluminum holder topped by a carbon connector plate that also holds the cable guiders in place. The slipper can also be replaced by a gear diff in the center. Its supereasy to access the slipper or central gear diff.
The lightened 7075 T6 aluminum uprights are same left and right and feature 3 camberlink positions.
The Serpent SDX4 front and rear wheel hex are 12mm industry standard size. The hexes are clamp type and anodized to last. Flanged wheel nuts are included to keep the wheels in place.
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 buggy body . 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.
Durable Serpent designed wheel are included in white color for front and rear (tires and inserts are not included). Rear wheels are same as SRX2 and SRX4, the front ones have a different offset and are new. Compliant to the latest IFMAR rules.
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 insert plates are standard. The front arms have 2 shock angle positions.
Steering blocks and c-hubs
The SDX4 lightweight composite steering blocks are combined with aluminum 7075 T6 c-hubs. The c-hubs has 2 positions for roll center, and can be further fine tuned by using more or less shims. The c-hubs are 5 degree, other optional ones are 0 and 3 degree.
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 coated aluminum steering brace has 2 holes to choose from. The servo saver has a pre-load nut to easily set the desired tension. The SDX4 steering system is mounted on a carbon fibre u-bracket which also connects the front left and right sides and acts stiffener.
The SDX4 hard coated lightweight 2mm 7075 T6 aluminum 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.
In the rear the SDX4 features a carbon fiber 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.
The servo is mounted in the car with a stand made from alu and carbon parts, and is mounted on the center line 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.
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 aluminum 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 spring steel for smooth operation.
Balljoints / trackrods
New style and material ballpoints for smooth suspensions and steering. The outer steering balljoints are angled to clear all rims/tires . The track rods and camber links are made in thin but durable spring steel with L/R threading for easy adjustment.
Serpent SDX4 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.
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 camber link positions. 3 inner and 3 outer. The rear one has 8, 4 inner and 4 outer.
Very durable aluminum shock stays combined with a small bushing and lightweight composite flanged nuts.
This SDX4 light slipper-clutch unit, is a spring loaded 3 pad version, allows to control the power distribution.
