In this post, I will list the electronic system I use and a link to my video showing my super racing machine.
I am using a Hobbywing ESC 60A, a brushless motor, 4370KV, and a 3S LIPO.
Here is the link to order the brushless ESC 60A. This ESC can easily handle 3S LIPO. With a 3S, this ESC can run up to a brushless motor of around 4000KV. Here is the Surpass brushless motor. These ESC and motor are waterproof so they are excellent choices for an off-road car. For the size of the battery holder of DT-02, I use a 3S LIPO of 1500 mah.
To stabilize my super runner, I use wheels of extra width. I chose a set of wheels of 80mm diameter. To connect these wheels, you will need special connectors for the front wheels. With this special connectors, you can insert bearings into the front wheels. For some wheels, you will need to trim the hole of the wheels a little.
The Tamiya special wheel connectors are expensive. You can get the wheel connectors made by GPM which is much cheaper.
