If you like my Giant Lego prints, please support by tipping me. Thanks!
Here are the files for the 5 x scale LEGO Technic motors I designed to make my Giant LEGO Go-Kart radio controlled!
Files are provided as-is.
There are two versions of the motor, the shells of these two motors are the same, but the front mounting plates and motor mount plates differ.:
- Steering motor uses a brushed style motor with planetary gearbox and potentiometer feedback via a T2.5 belt.
- Drive motor uses a brushless SK3 motor with T5 pulley to transfer power to the Lego axles.
Motor parts used:
Warning !! I tried a couple of cheap clones of the Monster Moto Shield by Sparkfun, and they were terrible! One of them had a broken channel, and the other just didn't operate as expected. I have read various warning on-lin with these clones, they heat up much more than the real deal and thus are pretty dangerous.. avoid the clones!!
Parts required to complete the electrical connections in the motors and connector plugs:
The LEGO Antenna has a recess in the base that will take a small
Orange R610V2 receiver, however, I had issues with my receiver and so didn't use it for my tests.. see video.
