The S120 pro is a revolutionary innovative 1/12th scale car design based on the F110 SF4.
New innovative design for the rear pod with side bearings in linear guides replacing the sidelinks. With a traditional sidelink design, designers use long side links to have the relative roll movement between pod and chassis as linear as possible. But no matter how long the links are, there is always a longitudinal component in the roll motion. With the new side-bearing design, the roll motion is completely linear and independent thus the cornering is completely independent from accelerating or braking. While it doesn’t change much on the mid corner handling of the car, this gives an unprecedented consistency and stability at corner entry when the braking and steering input overlaps and at corner exit when the throttle is applied before the steering is completely straight.
What you feel is, you can brake harder into the corners and accelerate earlier out of corners.
Lipo longitudinal or Lipo transversal with narrow chassis design. The new side bearing design opens the possibility to use both inline
Special holders for inline lipo configuration included in the kit, optional for lipo cross configuration
Full strength topdeck to prevent longitudinal flex and keep torsional flex on a reasonable level. 2 body mount positions are included. It does not need to be removed to exchange the lipo in any configuration
1-screw Lipo mount in all lipo orientations. For the inline lipo orientation, the lipo is held by an aluminium holder that can be removed though the chassis bottom.
For the transversal lipo orientation, the lipo can be pulled through the side. This is possible thanks to the no-link design. No more excuses not to charge the lipo in the car.
The easy to work on and strong front suspension from the F110 SF4 is evolved for the pancar specific demands. All screws are easily accessible.
Double short tube system for the rear roll damping. Compared to a single tube design, it gives a 100% symmetric driving feel.
The tubes also work as roll limiter, which reduces the risk of dirt getting into the tubes or oil leaking out from them.
New ultra-low center of gravity rear pod. The angled rear plate gives torsional stiffness, protecting the rear shaft and bearings, while keeping all masses low in the pod. This increases rear grip of the car, and preventing grip roll in high grip conditions.
The bulkheads are completely redesigned to keep masses as low as possible and at the same time have a strong pod that survives rather hard crashes
The rear shaft mount is completely new and innovative. Ride height and wheelbase can be adjusted very precise with shims.
New ball diff with an additional long-life thrust bearing that runs very smooth and still allows a strong locking effect to outperform todays bevel gear diffs on most surfaces
Rear carbon shaft with variable diameter.
The carbon shaft is reinforced by an aluminium sleve at the bearing and where the pin connects the aluminium thread insert with the shaft. This makes the shaft one of the strongest on the market.
With the bigger (8mm) bearing on the right side also helps with the higher load of the right side bearing because of the bigger leverage and the spur gear.
The thread insert goes all through the shaft until the pin, so the tension force of the thread does not pull on the gluing.
New improved shocks, much easier to build, with same, bigger piston diameter as the Project 4X, and the Project 4X bleeding hole for easy rebound adjustment
After the huge success of the F110 SF4, The step to develop a 1/12th scale car on the same platform was logical. The focus was to make the car easy to work on and durable without sacrificing performance.
We proudly present another Masterpiece of innovation and performance.
Enjoy the assembly and feel the difference at the racetrack.
Serpent S120 pro 1/12thscale electric 190mm rc car
Rear wheel drive, kingpin front suspension, rear pod direct drive motor (not included)
Trackwidth front 168mm Trackwidth rear 169.5mm (adjustable with shims)
Rear adjustable range +2mm (shims)
Front adjustable range +3mm (inserts in 0.6mm steps)
Symmetrical chassisplate for even flex and torsion in high quality carbonfiber with big cutouts for lowest possible electronics positioning and low weight
carbon fiber radio plate which also serves as front topdeck, eliminating the need for a separate floating servomount
the car is consequently optimized for 2s shorty lipo use.
The battery can be used in inline and cross configuration. In inline configurateion the electronics get placed besides the battery. This is mainly recommended for stock class racing with low power and small footprint ESCs to maximize cornerspeed
For cross configuration there is a electronic holder available to mount the electornics in the center in front of the battery. This configuration optimizes forward and braking traction and gives more space for bigger ESCs used in midified racing.
Alu battery holder with lowered battery position for lowest possible center of mass and highest cornerspeed.
Battery can be removed from the car with only one screw. No more excuses not to charge the battery in a lipo bag.
The battery can be addached to the battery holder with battery tape or velcro tape or it can just lay loose in the tray.
The battery holder can be opened with one single screw and the battery can be removed and replaced on the side. This works to the left and to the right and gives total freedom for electronic placement.
new bigbore shocks
The shock internals are optimized to use a bigger diameter piston while using the same springs compared to the previous S120 versions.
The shock seal cartridge and piston are the same easy to use system as in the 4x evo.
A bleeding hole in the bottom which is closed by tightening the lower balljointmakes rebound setting as easy as never before
threaded shocknut with o-ring for safe and easy preload adjustment
Front and rear adjustable wheelbase.
Front wheelbase and caster adjusted with inserts with a tight tolerance to keep all settings even in hard crashes
Front suspenssion is very lightweight and extremly durable at the same time by matched component flex characteristics
Kingpin suspension with fixed lower arm and upper wishbone with turnbuckle for easy camber adjustment and double adjustable ackermann geometry
Strong composite steeringblocks with 2 Ackermann positions, The steeringblocks feature inserts, which allow to change the kingpin inclination (inwards or outwards) to adjust the camber on high steering angles and the rollcenter at low steering angles
Suspension geometry is not influenced by wheelbase changes
The servomount in the fixed front arm ensures exceptional precise steering response. Longitudinal and torsional flex don’t influence the steering.
