RC Tank Warfare community hobby forum

This design proved to be unreliable and very noisy. Cardan gear collapsed because of very high revs. I refused this design. Nevertheless, I got some experience and began to think how to make the design reliable.

Subsequently, the transmission of the tank was completely replaced with a new one using a bevel gear and a planetary gear. The engines remained the same.

Speechless!

The use of brushless motors in rc tanks was not the best choice, because the motors have a weak sensitivity. In the end, I chose brushed motors 540. To manage the motors, a board was purchased Tank Control V3.
Now the model has this transmission.

Engineering masterpiece

From Christian Ludwig ordered a set of uper hull KIT and some accessories

Preliminary fitting of parts

My jaw almost hit the floor, when I saw those drive shafts with inboard and outboard constant velocity joints (Universal couplings) That's a drive train I've not seen in a model tank before. In most WW2 tanks a propellor shaft ran from the engine in the back to the differential at the front. Your arrangement is beginning to hint at that.. Truly knocked out by the level of engineering excellence here.
A question, though, K., will you put a deck above the drive shafts to provide a mounting plate for the MFU and other components?

Thank you all for your interest!

I plan to place the elements as follows: a speaker at the rear of the tank behind the engines; battery in the center between the motors; control board in front of the bevel gears.

Fastened the rear traction loops and installed the rear plate
