I guess you know that the Wltoys 12428 steering mechanism has lots of 'not good' traits, like getting stuck in sand or mud, wobbling, and having a low turning angle. Most of my RC cars have bell crank steering, so I decided to upgrade this car too. 

This is the first (3d print-based) version, which is not perfect and has not been tested for durability. 

What you need as an extra

  1. rod linkage (preferably with adjustable length)
  2. two M3 bolts 13mm long from suspension (if you plan to change the stock) or order search on Aliexpress by “M3 12428-0099”, I used this - https://s.click.aliexpress.com/e/_DlK7D6b
  3. two M 2.5 20mm bolts and two nuts. I used from there
    1. bolts - https://s.click.aliexpress.com/e/_DChSrTd 
    2. nuts  - https://s.click.aliexpress.com/e/_DmJzKkT 

Reused part:

  1. all the other rods used in steering are stock

QA

  1. What about stock suspension if I want it to stay
    1. it should fit since the pannel that holds the bellcranks should fit right under the shocks
  2. Is the project done
    1. NO!!! it is just a firs version, not fully tested yet but will be soon, please subscribe to my youtube channel so I'd know that you are interested!!! https://www.youtube.com/channel/UCLE0Gmir5LrE8t9jllJq6vQ?sub_confirmation=1 

 

Ongoing project with vertical shocks
