As always, it took a little too long but I hope it will be worth it.
This time I managed to get my hands on drawings and 3D scans of absolutely all the parts of the original vehicle.
This takes the accuracy and detail of this model to a much higher level compared to my earlier models.
There have been some problems regarding the misuse of my STL for commercial purposes, so I decided that the next release will be a kit and RTR model only.
This gave me more options, as I don't have to worry about making parts that can be printed by anyone and easily.
The model therefore contains a large number of resin parts, some of which I was only able to print on the fifth attempt before I had designed a part that could actually be produced.
In addition to the high detail, resin also provides the advantage that the kit contains a small number of parts.The relatively small number of the parts...
As for the lower hull - it is made in a combination of ABS and Nylon.The entire front axle and all the printed suspension parts are made of Nylon.
To produce such small parts with the required durability, the use of Nylon is essential.
The steering relies on metal tie rods and ball joints.
Its development was quite challenging.There were 8 versions before I reached the desired result.
It could have been simpler, but I wanted the servo steering to have no negative effect on the axle suspension.
Some elements of the front axle are oversized compared to the original, but I kept all the elements and parts of the original axle.
Except for the steering, of course.
I tried to make the steering according to the original mechanism, but it didn't work well.
Maybe it will work for a 1/6th scale model.We'll see.
Space inside was of course limited, so in the end I was forced to program my own control software.
I don't want to talk much about it yet.
It handles 6 channels but probably less will be enough.We'll see.I'll have to order the DumboRC controller, which will probably be part of the production model.
I set some goals which after a long development I finally managed to meet.
- wheels with bearings
- the most accurate replica of the front axle possible
- functional front suspension
- proportional steering through a combination of wheels and tracks
- functional lights
- all electronics hidden under the hood and floor (compact suspension system required)
- active cooling of electronics
- tracks tensioners
- as always, the possibility of removing every important part for servicing and maintenance
Two motors, size 180 - 100rpm.
1.8kg.cm torque/load
9kg.cm (!) torque/stall
So that's a total of 3.6 - 18kg.cm of torque.
The only thing I would like to add is some sound.
Maybe I'll figure it out somehow.

First sample of details.Drivers visor.
Some may find it unnecessary, but it's my way of creating and I wouldn't enjoy it so much without it.
I'm always pushing it further.
Lower hull.I have to raise the suspension by some 2-3mm i guess, but that's also part of the development.
