X20FWD 21 improves on the very successful X20FWD touring car. The chassis is based on the popular 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. And it uses the all new dual ball bearing DJC shafts and our new Steering hub allows adjustment of Axle height, offset and Roll center.

X20FWD story:
X20FWD 21 is based on the design of the X20 touring car.

The chassis is based on the popular 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 Ackermann 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 X20s grip and feel for whichever track you are on.

Understanding the Eryxs sway bar system then combining with 4X concepts, the all new X20 Low Centre of Gravity (LCG) Anti-roll bar system can 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!

Drive train ratio:
The thought about the X20FWD21 was always for stock racing, but with our new drive train ratio 38/21 its easier to change the gear ratio from 2 to 6.5

Battery mounting system allow different layout for the balance motor weight more move to center, to keep balance for using a shorty battery in all possible conditions.


Suspension arms:
The front and rear suspension arms are from the successful X20 and can be used with or without the optional carbon X stiffeners.


Battery mount options:
You can use 3 different battery layouts in the X20FWD21 car, to create the best weight distribution for each track.


Center battery possition


The side battery possition


Geardiff:
The nicely shaped rear differential features moulded internal gears which makes it super smooth. The compact and light unit holds a good amoun t of oil to deliver consistent performance throughout the run. It is fast and easy to take out and re-mount the differential.


Upperarm mounts:
The suspension brackets are adjustable with our 1pc suspension brackets shims available in 1mm and 2mm.


Bearing blocks:
The proven X20 bearing blocks with tradition Cam type belt adjustment for the ideal belt tension


Bumper and body mounts:
Impact proof bumpers and new body post position specially designed for the X20FWD.


Optional rear flex system:
Rear centre flex adjustment with butterfly style stiffener.


Antiroll bars:
The ultra-low antiroll bars are available in different sizes.


Motor/Servo mount:
Motor & servo mount for complete flex control.
The motor and servo mount are connected to create a new way of flex control.


Main new features

DRIVESHAFTS:
The all new dual ball bearing DJC shafts in the front, and in the rear  the all new ball raced CVD are included as standard. Giving ultra-smooth & silent torque application throughout the suspension and steering travel


STEERING BLOCK:
Keeping with our successful dual pivot ball suspension system, we have created even more adjustment to fine tune the handling characteristics.


Our new Steering hub allows adjustment of Axle height, offset and Roll centre.


Utilizing these options have allowed our team drivers to create more corner speed over the previous model.


Side lipo mount:
Also included in the X20FWD 21 is the side lipo mount.
