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.
The new side bearing design opens the possibility to use both inline and cross lipo orientation while keeping a narrow chassis design.
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.
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 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.
New 2-position servo mounting plate which works as front topdeck at the same time, preventing mutual influence between longitudinal chassis flex and steering.
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.
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.
