RC Tank Warfare community hobby forum

I decided to build this model after watching a video on YouTube by the user builtbyWikander, whom I cordially greet, and with whom I have not yet had the opportunity to exchange even a word.
I started searching the internet about tanks used by the Polish Army in WWII and came across 7TP. Enchanted by his um... strange silhouette for me, I started looking for photos, sketches, etc.
Then, in DesignSpark Mechanical, I made some sketches and created STL solids for printing on a 3D printer.
The bathtub was made of 3mm ABS boards as it used to be... Obecnie zmieniam wannę na sklejkę 12 mm żeby wszystko było bardziej sztywne i ułatwiało montaż

I see some interesting aspects of this 7TP project: there appears to be a wooden hull pattern and a hexagonal wrench (known in the US as an Allen Wrench), maybe for a sprocket drive axle. I would think that a hexagonal axle from a final drive gear through the hull, fitted through ball bearings could help make a strong drive assembly.

The visible Allen key served as a temporary axle to hold the cart together.
An M8 hexagonal bolt was to be inserted into the drive wheel as an axle and locked on the other side with a CNC clutch. Next to the clutch was the transmission.
I am currently trying to imitate the bolts and reinforcements of the rear fuselage.
0.8mm sheet metal and pointed rivets. I would like to stretch the tracks almost like in the original
