This kit is a chassis to use the Superscale2020 active suspension unit effectively. It features a compact package that combines torsion bars and active suspension in the size of the Tamiya M chassis (wheelbase 239mm).
This model also uses gripped tires for a more realistic scale appearance. We recommend using a DC motor for the crawler or a multi-pole brushless DC motor to enjoy realistic behavior at very low speeds.
Drivetrain
The drivetrain of this kit is designed to maximize the use of Sakura D5 parts available to everyone. As a result, it is possible to use active suspension at a lower cost than collecting the necessary parts individually.
A steering gyro is not necessarily required, as the tires provide some grip.

Superscale2020
The Superscale2020 “SS” unit is a key component of this chassis and should be purchased here.
1, Servo and torsion bar box assembly
Front. Install 9*17*5ball bearings and secure servo with M3*10 screws. Do the same for the left side.
Torsion bars are printed with PETG. Please check the print settings.
Insert the torsion bar into the suspension arm. Use a rubber hammer or similar tool to gently drive it in; use a Zig to drive in the appropriate amount. Do not install the servo horn at this point.
Install 5*10*4 bearings on the sus arm. fix the servo with M3*10 screw. Do the same for the left side.
Install 9*17*5 bearings and spring bars as for the front side. The spring lever is different from the front side, so be sure to check that it is springlever_R.stl and that the installation orientation matches the diagram.
2,Superscale2k20 “ss”unit Unit initialization
First, use arduinoIDE on your PC to connect to SS unit. Make sure you have the latest version of the firmware. The latest version is Ver1.22 (13 Sep 2022). You can check the version on the serial monitor. Then turn the potentiometer to adjust the offset value to 0, and turn off the power once it is done.
3, Neutral position setting for all servos.
Due to the space limitations of this chassis, it is necessary to connect each servo and SS unit as follows in order to reverse the servo rotation direction.
SSunitRL output>FrontRight servo
SSunitRR output>FrontLeft servo
SSunitFL output >RearRight servo
SSunitFR output >RearLeft servo
After connecting all servos, place the SSunit on a flat surface, turn on the power, and in a few seconds, all servos are in a neutral position and stable. Turn down the power.
Adjust the neutral position and the axle position with reference to the figure. The servo horn is tightly engaged with the servo output shaft when the screw is tightened.
Set up the left side in the same wayNote the mounting orientation of the ball end!Set up the left side in the same wayNote the mounting orientation of the ball end!
4, Frame Assembly
The steering servo is secured with double side tape.
Then connect the front and rear frames.
5, Front axle assembly
Fix the knuckle clamps to the suspension arms using Sakura D5 M3*12 flat screws.5*10*4Ballbearing. axle bolt.
6, Brace installation
Install the battery holder.The front and rear braces are attached with double side tapes.
7, Drivetrain
Use standoffs and gearbox braces to ensure frame plate rigidity.
The gearbox brace is also used as an ESC mount.
Fix standoffs from the back of the rear frame as well.

How to get the STL Data
You can Download this model`s Full STL data from crafthub.io
This is a suspension Conversion kit. To use SuperScale2k20 SS Unit, This kit can use the full potential of the SS unit instantly. And you can get the realistic motion for your Yokomo YD-2E/S chassis.
This is an STL Data kit
You have to print out all parts by yourself. The material you should use is ABS or ColorFab HT, etc. otherwise the parts don’t have enough rigidity.PLA is not recommended
Future
Design for Yokomo YD-2 E series /S series
Active suspension and conventional suspension hybrid.
For Drift Car, Don’t need so much torque. 5-10kg may be enough, However, a metal-geared servo is required.
YD2E/YD2S Both types of data are included.
ServoHolder

1, Installation
Use M3 screw, M3 Nut and gently insert to the M3 Nut position
Use the screw to pull the nut into M3 Nut position
Insert Square nut into the slot.
2, High Torque Servo installs
Only for this part, you have to use M3*6 screw, instead ofM3*10 screw to avoid not interfering with fixing the screw.
3, Remove the bumper
The Bumper fix screw is used to fix a servo Bracket
4, Swap the Strut tower bar(Front)
Front Strut (Remove the original Strut Tower)
Remove the ball end and fix it in the correct position Use a Tamiya Fluorne coated Stabilizer Ball connector set For the front, use this one.
Assemble the front Strut tower by adding M3*15 screws for the front. Do not over-tighten. Check for minimum play and movement.
The assembled strut tower needs a little bit of friction. If this part is too loose, the SS’s multiplier value can’t increase, and serious oscillation will occur and won’t stop. However, regular suspension linkage parts have to always be very smooth.
5, Swap the Strut tower bar (Rear)
For YD2E
For YD2S
Assembling the Rear Strut tower: (Assembled)
Use an M3*12 screw for the Rear. (Do not over-tighten)
Check minimum play (The arms should move easily.)
The assembled strut tower needs a little bit of friction. If this part is too loose, the SS’s multiplier value can’t increase, and serious oscillation will occur and won’t stop. However, regular suspension linkage parts have to always be very smooth. Use a Tamiya Fluorine coated Stabilizer Ball connector set For the Rear, use this one.
6, Mounting the servo holder
Front side
Use the screw that Yokomo original Bumperfix used.
The *Front servo holder has 3 screws. The rear servo holder has 2 screws.
Rear Side
