<b><font color="red">If you like my Giant (Building Block) prints, please support by tipping me. Thanks!</font></b> Here are the files for the 5 x scale (Building Block) Technic motors I designed to make my Giant (Building Block) Go-Kart radio controlled! <b>Files are provided as-is.</b> 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.: <ul> <li>Steering motor uses a brushed style motor with planetary gearbox and potentiometer feedback via a T2.5 belt.</li> <li>Drive motor uses a brushless SK3 motor with T5 pulley to transfer power to the (Building Block) axles.</li> </ul> Motor parts used: <ul> <li><a href="http://amzn.to/2lhOW2Q">SK3 3548-700KV</a> Brushless motor</li> <li><a href="http://amzn.to/2C8bZro">80A Brushless ESC</a> for R/C car</li> <li><a href="http://amzn.to/2BRVnQ9">940D Motor</a> with 264:1 planetary Gearbox</li> <li>Sparkfun <a href="http://amzn.to/2C6n6AS">Monster Moto Shield</a></li> <li>Bourns 6630 Series <a href="https://uk.rs-online.com/web/p/potentiometers/6930733/">5K Potentiometer</a></li> <li>Potentiometer timing Belt <a href="http://amzn.to/2C8lw1l">58 tooth T2.5 6mm x 145mm</a> or RS part: <a href="https://uk.rs-online.com/web/p/timing-belts/4744990/">474-4990</a></li> </ul> <b>Warning !!</b> 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.. <b>avoid the clones!!</b> Parts required to complete the electrical connections in the motors and connector plugs: <ul> <li>Stereo 1/4" jack socket RS part: <a href="https://uk.rs-online.com/web/p/jack-trs-connectors/2083849/">208-3849</a></li> <li><a href="http://amzn.to/2BVa8lD">Stereo 1/4" jack plug</a> or RS part: <a href="https://uk.rs-online.com/web/p/jack-trs-connectors/813-8844/">813-8844</a></li> <li><a href="http://amzn.to/2BQhE0P">Mono 1/4" jack socket</a> or RS part: <a href="https://uk.rs-online.com/web/p/jack-trs-connectors/2055440/">205-5440</a></li> <li><a href="http://amzn.to/2C98YH9">Mono 1/4" jack plug</a> or RS part: <a href="https://uk.rs-online.com/web/p/jack-trs-connectors/8138835/">813-8835</a></li> </ul> The (Building Block) Antenna has a recess in the base that will take a small <a href="http://amzn.to/2lpO4IN">Orange R610V2 receiver</a>, however, I had issues with my receiver and so didn't use it for my tests.. see video.
