Make one 1/16 sd.kdz.234/2 PUMA

[tankme]

Well I just purchased the IS-3 files and I think I've got all the ones on Thingiverse. Now I just need the time to print and build them.

I only received part of the mail, and the rest will arrive in a few days
Fortunately, all the electronic equipment has been sent. I tested it and found no problem

The water transfer sticker I purchased on Taobao used less than 4 euros.

You can see in the picture two sets of linkage steering mechanisms, as well as an unfinished smoke system.

There are still some parts that are not in place yet. I believe I will be able to complete them soon

According to my calculation, the weight of my PUMA fully loaded (including batteries and various electronic systems) is 1.2-1.4KG. In fact, I believe that 1/16 RC tanks should not be too heavy, and lighter weight can ensure lower costs. Moreover, due to the lighter load of the vehicle, reliability will also be greatly improved.

Due to the fact that the virtual position of the metal tie rod is larger than that of the plastic tie rod, and there are some errors in the 3D printed parts, six plastic and copper tie rods are used inside the chassis, while the outer side of the chassis is a pure metal tie rod

This is a really nice project.

I am really impressed with the project. I'd call it a scratch build just with CAD and a printer instead of card and glue.

[Herr Dr. Professor]

Another fine quality of this project is the neatness of the design, the fitments, even the printing.

Looks really very good, excellent work
Would love to see some running videos aswell

Due to the fact that the lower part of the chassis of PUMA is too narrow and the middle part is filled with mechanical structures, it is necessary to create a platform on the chassis for fixing electronic equipment.At the same time, the triangular cutout on the platform can fix the wires. Because in my experience, sorting out the wires inside the model is very troublesome.

I powered on and tested that the suspension and steering parts worked well. However, due to the low voltage, the power of the motor is weak, and the driving speed on flat ground is very slow. Therefore, I purchased a new 3S lithium battery, a new electronic governor, and a step-down module. Since the main board can only use 7.2 volts, I first need to connect the electrical regulator and step-down module responsible for the main motor in parallel. This way, the system responsible for advancing has a voltage of 12V, while the rest of the system is still 7.2V
