# Before you start

Know what you're getting into...

The idea for the HRF Tank project came from an earlier, smaller RC tank I built a few years ago. While driving that vehicle, I managed to overheat and burn out the motors twice. It also struggled on small rocks, the tracks slipped on smooth surfaces, and the hull was made from large single pieces, which made modifications and repairs unnecessarily difficult.

That was when I decided to start from scratch and build a new tracked vehicle that would be more capable, less prone to overheating, and much easier to modify and repair.

I also wanted to use the project as an opportunity to learn new skills, including PCB design and SMD soldering. I wasn’t aiming for a quick “just get it done” build - I wanted to challenge myself and create a platform that could be improved over time.

That is how the HRF Tank was born. It gradually evolved into what I jokingly call **“The Overengineered Tank.”**

As you can probably tell from the photos and specifications, this is not a typical weekend project. However, I have tried to make the platform as modular and modification-friendly as possible. I’m also providing the original **STEP files**, so you can adapt the design or create completely new parts.

I hope building your own version brings you as much enjoyment as developing this project brought me!

### Important notes

Building this project will take some time, effort and money.\
Before you start printing, decide how complex you want your build to be. The HRF Tank can be built as a relatively simple RC vehicle, or expanded with custom electronics, telemetry, lighting, cooling and other features.

For a basic electronics setup, you can use:

* two drive motors,
* two ESCs,
* a standard PWM RC receiver,
* and a suitable power system.

If you want to explore more advanced features, the possibilities are much broader.

Consider the following questions before choosing which parts to print:

* Do you want to build a simple version or include additional features?
* What is your experience level with RC systems and electronics?
* Is this your first RC vehicle?
* Would you like to assemble and use my custom controller PCB for lighting, cooling and temperature monitoring?
* Do you need liquid cooling, or would a simpler air-cooled setup be sufficient?
* Do you want headlights and tail lights, or would you prefer to leave them out?

Once you have decided on your configuration, choose the appropriate **STL files** to print.

If you cannot find a part that fits your needs, use the corresponding **STEP file** to create your own modification. And if you come up with something useful, consider sharing it with the community!

### About the build manual

Some parts in the manual may look as though they have already been used or pre-assembled. This is because I created the manual by disassembling a working version of the HRF Tank.

In **Section III**, you will see how I wired the electronics in my own build. You do not have to reproduce my setup exactly — feel free to adapt it to your own components and requirements.

One final warning: assembling the tracks is a pain in the ass. However, they work surprisingly well once assembled. You have been warned. 😆
