JagdTiger

This section is for builds that are not strictly Tamiya or Heng Long. For instance, replacing the electronics from a WSN or Matorro, or even a scratch-build.

Good health, dear forum participants!

I want to share with you my success in the construction of Jagdtiger. I started this project a long time ago, back in 2015. At the moment the project is not finished yet, since I had to suspend it because of the birth of my son. My son has grown, and now I hope to continue building as free time develops.

The project was started with the purchase of Tamiya King Tiger lower hull and the growl.

Lengthened the lower hull by adding a metal plate

More interesting surprises coming our way, then, K. ? :) One real surprise is to see someone saw a rear of a Tamiya King tiger off :O Now that is bold (and expensive :shifty: ). I sawed the rear of an Asiatam Pz IV hull off for a project, but that was minor league compared with this. We look forward to more ingenious bits of engineering from you.. :thumbup:

Thank you!
I saw your project and was impressed by your attention to detail.

This is an absolutely magnificent build. Keep up the great work. What type of track tensioner is that? It's a very nice design with a much more pronounced way of dialing in your settings.

Then I installed the gearboxes and assembled the running wheels.

If memory serves me right, this is the Henntec tensioner of the early version. I bought it from Dominique rctank.de (not advertising), but now it is not available for sale.

After that, I started experiments with gearbox and motors.
The main idea I pursued was to give the model a high power. To this end, 540 class brushless motors were purchased.
Jagdtiger is a tank with a front-wheel drive. The 540's are heavy. I did not want the front of the tank to be too heavy. To facilitate the front of the tank, the motors were placed in the rear part, and the gearbox drive is realized using cardan mechanisms.

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.

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.

My jaw almost hit the floor, when I saw those drive shafts with inboard and outboard constant velocity joints (Universal couplings) :O That's a drive train I've not seen in a model tank before. 8O 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. :clap:
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.
