The F110 SF4 is a revolutionary innovative design on the 1/10th Formula 1 car market.
Made from racers for racers.

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 and cross lipo orientation while keeping a narrow chassis design.

Special holders

for lipo and electronics included in the kit for both configurations

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.

The race-proven and strong front suspension

from the F110 SF3 is evolved with more width to increase the stability of the car, especially on corner entry. It also prevents traction roll effectively.

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.

New 2-position servo mounting

plate which works as front topdeck at the same time, preventing mutual influence between longitudinal chassis flex and steering. This leads to a new, very precise steering feeling.

New wing mount which is independent of the rear pod movement.

It is connected to the chassisplate via sideplates that run under the rear shaft and diff. This makes the suspension work much more like a independent suspension car by massively reducing the inertia of the pod. In addition, the angle of attack of the wing is very constant compared to the traditional design. It also allows to run more rear droop without making the car unstable during high speed cornering.
What you feel is superior high speed rear grip, more stability over bumps, and when you overdrive the car, the hobbling effect of the rear is prevented in most cases.

New double short tube system for the rear roll damping.

Compared to the 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. At the same time, body touching with the pod is largely reduced.

The bulkheads are completely redesigned

to keep masses as low as possible. They are positioned more to the center to reduce inertia.

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 shaft with variable diameter.

With the traditional rear shaft design, aluminium reaches its limit when it comes to impact resistance. This leads to aluminium being not the usual choice for rear shafts. Also the right bearing is stressed far more than the left bearing.
With the bigger (8mm) bearing on the right side, both problems can be overcome and a lightweight and still strong rear shaft is the result.

Pod Bulkheads completely keyed to the graphite plates to avoid tweak issues

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.

Always looking for new innovative improvements, Serpent designer David Ehrbar went straight back to drawing new improvements for the F110 car after winning the ETS title with the predecessor, the F110 SF3. Nobody knows the strengths and weaknesses of the old car better than David. Although the platform was winning the ETS championship and together with Tim Benson the F110 SF3 was winning half of the races of the season, David decided to go for an all new, revolutionary design to have another shot on the big titles instead of making small updates on the old platform.

David has proven that the car is successful on any surface, with only closely missing the World Championship title at the very first race with this car, and winning every single race since, including German Nationals and the ETS opening race.

Now we proudly present another Masterpiece of innovation and performance. Enjoy the assembly and feel the difference on the racetrack.


Serpent F110 SF4 1/10thscale electric 190mm rc car
Rear wheel drive, kingpin front suspension, rear pod direct drive motor (not included)


Symmetrical chassisplate for even flex and torsion in high quality carbonfiber with big cutouts for lowest possible electronics positioning.

Front topdeck/Radioplate

carbon fiber radio plate which also serves as front topdeck, eliminating the need for a separate floating servomount

Ball diff with 12 balls included

Can be equipped with 18 balls on outside diameter for better durability in higher power applications

Flex adjustment

The radio plate is mainly mounted to the front suspension and center bracket. However there are additional stiffener posts included which can be removed for additional front flex. The front radioplate/topdeck and the rear main topdeck provide well balanced flex characteristics

Battery/electronics layout

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. For cross configuration there is a electronic holder included to mount the electornics in the center in front of the battery. The servo can be mounted in 2 configurations.

Battery-holder inline

Alu battery holder with lowered battery position for lowest possible center of mass.
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.

Battery-holder cross

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. 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 wing with

adjustable flaps, covering a range from very low downforce to very high downforce. Only one main front wing for all conditions.
Bodypost attached to the frontwing.

Rear wing adjustable

in 3 vertical positions, and free to place horizontal position, which can easily be changed with one hex wrench, as the screws go into a threaded alu endplate.
In addition the upper rear wing flap can be adjusted in three positions.

Wing to chassis mount included

Car is designed from the beginning to monut the wing to the chassisplate

Front wheelbase

and caster adjusted with inserts with a tight tolerance to keep all settings even in hard crashes

Suspension front

Kingpin suspension with fixed lower arm and upper wishbone with turnbuckle for easy camber adjustment and double adjustable ackermann geometry

Strong composite steeringblocks

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
