Englische Version
The chassis is based on the popular Medius mid motor design, using a light weight and strong 1 piece motor mount concept, without any interference between the front and rear chassis flex while still allowing center flex adjustability. The advantage for this style of design is to allow maximum flex capabilities without impacting the drivetrain, meaning smoother power delivery, more consistency and less chance of stripping spurs.
Suspension and Steering:
Using the last 4 years of development the X20 keeps the successful 4X proven pivot ball style setup allowing for easy and fast adjustments to camber, toe, track width etc. A new 2 point steering crank system has been implemented for more akerman adjustment, this coupled with 4X geometry guarantees race success!
Continuing from what we have learnt from other RC platforms we now introduce a new suspension arm design, allowing the ability to adjust arm flex! Multiple styles of carbon and other materials will be available as optional items to fine tune your X20’s grip and feel for whichever track you are on.
Understanding the Eryx’s sway bar system then combining with 4X concepts, the all new X20 Low Centre of Gravity (LCG) Anti-roll bar system is able to lower the sway bar point on the bulkhead without limiting the leverage point by connecting to the upper arm. A smart system which achieves the best of being LCG while retaining optimal performance.
The X20 features a more traditional approach to the shock absorbers in comparison to the 4X, making it more user friendly with less complication. We have focused on producing the highest quality components to ensure the best fitment. Utilizing our smoothest leak proof X ring we believe the X20 shock absorber is a game changer!
Drivetrain:
Our proven drivetrain is efficient and as light weight as possible for maximum durability, 7075 T6 Aluminium rear CVD’s and a Chatter free DJC system up front from Serpent spring Steel. Hard Anodized centre pulleys keep the Kevlar reinforced equal length belts running smooth and true. Coming as standard equipment we include the bladeless hardened steel outdrives connected to the ultra-lite front spool.
Medius concept Upper deck
Using the Medius design, having Split cut front for easy install while the rear are design and plan to let customer custom adjust flex by leaving room to cut and mount post to adjust flex.
All New 50mm shock dampers with 12mm shock body and Universal shock-springs
All new Shock system using the Eryx’s traditional style to give user the easy understand back into the Serpent Touring car platform. X20 focus on making the best fitment this time by create the smoothest Leak proof x ring. After countless of fitment test and x ring swell test, the X20 shock is the game changer.
Medius Motor mount for complete flex control,
Extremely low 7075 T6 aluminium motor mount, Working with the Medius design, this motor proof to separate the flex by the motor and the front and rear chassis flex.
All new impact proof bumpers and new body post position
In the front a strong bumper-set using a large size but light foam bumper which is sandwiched between the lower composite bumper and upper graphite holder. The flexible moulded body posts with swivel-system go all through. Optional body height systems are available.
Narrow Bulkhead Design with ball bearing sway bar mount
Multiple center Flex screws adjustment for chassis stiffeness
Optional Rear Center Flex adjustment with butterfly style stiffener
Ultra Low sway bar position
Understanding the Eryx’s sway bar system and combine with the 4x concepts, the x20 LCG Anti-roll bar system able to lower the sway bar point on the bulkhead without limit it’s leverage point by connecting to the upper arm. A smart system which achieve the best of being lcg and retain it’s best performance.
All New Front and rear Suspension arm with the X20 “X brace” stiffener
All New ackerman steering system
The ball raced aluminium steering system consists While adopter the latest ackerman and 2 point crank system steering rack.
Upper Arm mount and 1 piece shim system
All New Bulkhead with tradition Cam type belt adjustment
After 4 years of learning of the Project 4x, we took what we learn and evolve into what you see today. The all new Serpent X20 Medius. Using the same Pivot ball style suspension and geometry from the 4x, the New X20 Medius is a combination of the S411, 4x and what currently trending Mid motor design. With the advantage of the wide adjustment in a easy to understand approach, Customers can now enjoy our R&D result for the past 4 years of the 4x with a normal suspension system.

Suspension
Suspension system using the 4 year of testing and result from the 4x platform, keeping the Pivot ball style suspension and allow easy to adjust camber, track width, toe…. The X20 will continue the 4x suspension & steering geometry’s successful story.
Steering blocks / uprights
In the front and rear the same steering blocks/uprights are in use. The pivot ball system allows for easy and quick set-up changes and works very smoothly. In the front there are 4 Ackermann positions and shimming below the steering rod can be used for fine tuning of the bump steer characteristics. In the rear the system allows to set Reactive Rear Steering. This RRS system allows for a change of toe-in while the suspension compresses and thus increases corner speed.
Gear differential
The nicely shaped gear differential features molded internal gears which makes it super smooth. The compact and light unit holds a good amount of oil to deliver consistent performance throughout the run. It is fast and easy to take out and re-mount the differential.
Front spool
The coated aluminium front spool with lightened spring steel outdrives is a bladeless type which ensures superb handling and durability throughout the race. It is fast and easy to take out and re-mount the spool
Transmission
The transmission system consists of large diff and spool pullies and efficient low friction belts. The light build in centre shaft pullies are durable coated aluminium units.
Mid shaft section
The ball raced durable mid shaft design to be 1 piece with 2 pullies as well as the spur in place. The assembly is super easy to build and maintain.
