The Mission

I allways wanted to own heavy equipment. Excavators, Dozers, Wheel Loaders, and so on. But they were pretty pricy…then I stumbled over Bruder toys…and decided to start with something easy: A huge dozer built as a toy-rc-conversion - then I started a more complicated conversion: This Cat Skid Steer!

The Idea

  • Buy a Bruder Cat Skid Steer
  • Buy cheap remote (I used Fly Sky FS-T6)
  • Buy four (or if you prefer 2WD: two) small cheap servos for driving the wheels (I used Hextronik D-MG16) [1].
  • Buy one small cheap servo for the shovel (try Hextronik D-MG16)
  • Buy one strong standard-size servo for the main lifting arm (I used HD-1501MG)
  • Get some M3 screws and nuts
  • Print the parts listed below
  • Build it :-)
  • Have fun!

The How To

The build-video


  1. Hint: If you use 4WD and have trouble getting the servos in neutral (standing still) all at once - try using a ESC instead of the built-in electronics! But make sure, the ESCs don't have a brake and are running same speed in both directions
