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
- Design for Yokomo YD-2 E series /S series
- Active suspension and conventional suspension hybrid.
- Simple and reliable, easy to swap design.
- Fully compatible original suspension geometry
What is contained in this kit?
Nozzle Dia. 0.4 infill rate 30% vertical perimeters 3
What you need without this kit
- SuperScale2k20 SS unit
- Suitable servo *4
- 10A UBEC
- 3M Double Side Tape
Digital servo required
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.
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)
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
Use the screw that Yokomo original Bumperfix used.
The *Front servo holder has 3 screws. The rear servo holder has 2 screws.
Remove the original bumper and replace it with the Servo holder.
About the Rear screw. Use the screw that yokomo originally used.
7, Initial setup of SS unit
8, How to setup SS unit
You need to install Arduino configuration software. Please download from the link below.
You may download Arduino IDE software for your suitable platform. macOS or Win
Firmware needed from SuperScale2k20
*this firmware is pre-installed
First, connect the SS unit to the PC and set the offset to 0.
Next set BALANCE to 50.
The servo‘s neutral PWM value is almost 1500
*you should provide the power for SS Unit cause USB doesn’t provide enough power to move the servo neutral position.
Check all 4 servos in a neutral position, and then Set the servo horn like this.
Adjust The turnbuckle length, and then connect the servo and Strut arm.
Front and Rear Rod Length
All about the physical setup is done, please test the sample setting value.
Yokomo YD-2 sample setup value
This is the start value to set up the active suspension
For more detail, please refer to SS unit manual.
Front Suspension Setting
Rear Suspension Setting
It will be better to change more high viscosity dumper oil.
Body mount kit
Body mount post parts have compatibility with Yokomo Genuine Body mount rod. You can use your suitable third-party body mount. Or make a hole in the body and fix the body using a Body pin.
Do not use this file for commercial purposes without any permission.
This model was made with FDM 3Dprinter, the parts have some additive markings, however, no problem with those parts’ functions.
