thingiverse

If you appreciate my Giant Building Block prints, please show your support by tipping me. Thanks! Here are the files for the 5x scale Technic motors I designed to make my Giant Building Block 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 Building Block axles. Motor parts used: - SK3 3548-700KV Brushless motor - 80A Brushless ESC for R/C car - 940D Motor with 264:1 planetary Gearbox - Sparkfun Monster Moto Shield - Bourns 6630 Series 5K Potentiometer - Potentiometer timing Belt 58 tooth T2.5 6mm x 145mm or RS part: 474-4990 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 warnings online 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: - Stereo 1/4" jack socket RS part: 208-3849 - Stereo 1/4" jack plug or RS part: 813-8844 - Mono 1/4" jack socket or RS part: 205-5440 - Mono 1/4" jack plug or RS part: 813-8835 The Building Block 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.
